I came through the other video, thank you, your reviews are very good, you observe and talk about everything and the best thing is that you disassemble the parts to observe well what it contains, additionally you show and express the part numbers and name to be able to get and buy them
Dude. We both got these yesterday. Post review videos yesterday and you already have it brushless upgraded. Amazing. Great job. You are definitely my favorite basher upgrade master. Well done sir.
Thanks man It's been a pretty busy couple of days. As a matter of fact it's been a pretty busy month. I've put out far more videos than I normally do. It's been a lot of fun though!
@DoRC Same here. Back to back videos this week alone. I do crawlers and bashers. I did the new injora tire upgrade Monday then straight to the LHS Tuesday to film and edit the Grom. I can't find that ARA320753 servo mount anywhere??? Any ideas?
@hyperc5249 Unfortunately it doesn't appear to be available right now. I pre-ordered everything that they had in the option list when it was first released and the entire list disappeared. I'm really not sure how many people even got that adapter. Maybe I'm the only one but I doubt it. At this time though I don't think you can get it.
Wow man. That thing is ballistic on 3s. I like how they set up the suspension arms on this little guy. Super tough looking design. Thanks for sharing the upgrade and performance. 👍
Cool release from Arrma. We’ve been asking for a micro for ages. Hopefully if these sell well, we’ll get a 1/20th outcast brushless with full metal drivetrain. Would love a living room basher that has quick rotational capability for backflips off the little orange ramps
Thank you for the video. I just did the exact same setup on my granite grom, minus the rx and tx. Can’t wait to test it on 2s tomorrow. Hopefully my Arrma all metal diffs hold up.
Awesome 😎 That thing looks great on 2s Lipo and although a little sketchy, and out of control at high speed on 3s, it does look fun at 3s. I think along with the Gorgon, this may be another home run for Arrma. Such low prices on these two new durable, fun bashers, will surely have a ton of these under Christmas trees this year! I really don’t need the Grom since I have the full 4x4 3s granite. But that think looks so cool, and with the parts support of an established company like Arrma, this may make my Christmas list from Santa 🎅🏼 this year 🤩😂 Great informative, educational review. Regular guys like me appreciate people like you who do normal bashing vids that show us what to expect from these cars. Whether under out of box stock bashing conditions, or after kicka$$ hop ups like this Grom. 🤘🏼
Thanks Glad you enjoyed! It's actually pretty controllable on 2S with the brushless system but almost completely uncontrollable on 3S. I'll be bashing on 2S from now on.
Yeah it's surprisingly well tuned out of the box. For how small it is it actually handles better than some of the 114th and 1/16th scale trucks. Sorry about some of the bad camera angles I just got a new camera mount and I'm still getting used to it.
@RCvapor Yeah I think by the raw numbers there are better values out there especially given that this is brushed but I also think this car will have a lot of potential in the long run for upgrades and mods.
Oh wow well thanks for clarifying that. I work in a hobby shop and I've been using that as a selling point for these Groms which are flying out the door! They claim they have metal diffs. So thank you for the clarification. Keep up the good work bro.
Yeah Arrma is really good and making things sound just a little bit better than they are in their descriptions. They don't quite lie but they do carefully worship things.
@@DoRC They advertise it " 4WD transmission with robust metal gears " , that is nearly lying as diff gears are plastic. I dont appreciate when a company takes people for idiots.😡
@@Madprax I completely agree and this is far from the first time they've done something like this. The people who write these listings are very good at implying things that aren't true whille not quite crossing the line to overt false advertising. It's kind of like with the new 8S EXB RTR. If you read the description it appears as though there's all kinds of new updated pieces in the car when the reality is it's just the old EXB roller with electronics in it and slightly updated tires. I have found that they will specifically advertise anything that's good so if it doesn't specifically say something like "metal internal differential gears" You can bet they're probably plastic.
@@VetteWay2Fast Yeah it's not just the differential gears. The output cups on the diffs and the stub axles are also plastic. Arrma as always been good at not quite false advertising like that.
@@DoRC waiting for the parts.Now I have For the Arma Senton 4s upgrade parts in the Big rock.fits great 😃 Soo really happy.Runs really nice And now problem.
Yes they will all be for a specific gear combination. They had them all listed on their site but when they took all of the option parts down they took those down as well. There was a pretty good selection of them though so you should be able to get whatever you need.
It's neat but for me it's not going to replace the HBX 16889a pro as my recommendation for new folks and kids. Parts are everywhere where it's marketed as like 8 different brands and it''s already brushless, quick, and still cheaper.
The 16889 pro is a fantastic truck. Definitely what I would still recommend to most people so far. I'll probably end up sticking with the Grom just because it's going to have a lot of upgrade options and I love upgrading especially when the upgrades are small and cheap :-)
I have snapped two motor shafts on my Granite Grom. Running the Mamba Micro ESC and snapped the Castle motor shaft and a Amazon motor shaft. What am I doing wrong? Pinion gear? Can't be too much power, I ran the same setup on my Losi Mini B, no problems. Mayby the tires are too big? Never had this problem on any RC car before.
Oh man I want one of these! Looks like it would be a perfect candidate for my spare Castle Mamba micro Pro! Had the combo from my old ECX 1/18 Ruckus but it would just destroy the gears. I would love to throw it in one of these and then compare it with my 1/18 HBX brushless monster truck
I don't and it's probably not the ideal battery anyway. I think I just grabbed something I had from my FPV quads. Best thing to do is just measure out the battery tray then jump on Amazon and find something that fits and fits your budget.
I detail it out at the end of the video but it's the keenso 3800 KV motor on Amazon, hobbywing 10 BL60 sensored ESC, the ESC plate adapter from Horizon and receiver of your choice.
I hit 42 on the same set up on 3s and never flipped... you have to take out the 4 spacers out of the shocks and also cut the front springs 1.5 rings shorter
I have a Hyper go P16 race buggy with some upgrades. All metal shocks. Upgraded spur gear, wheelie bar, upgraded steering servo,I greased the gears. Been running 2S brushless stock system. It's great. But I will be honest I think I could build one of these and it would come out better and handle a little better then the Hyper go.. 👀
@Madprax to get the exact same equipment list yes but I will say that my 16889 pro could not handle 3S brushless with just about the same system without immediately breaking. The Grom handled it well so, whereas the drivetrain doesn't quite have the same specifications, it seems to be at least as durable out of the box.
Yeah I think brushless 2S is definitely the way to go. It does handle 3S but it's also pretty uncontrollable. Brushless to us gives it just that extra bit of power that it needs.
Awesome video, i just purchased two of these today. Will definitely be changing to brushless in one of them. How much run time did you get out of the 2s shorty pack.
Not entirely sure. The 2S pack I ran in the video also included the speedruns so that's going to knock down the time a bit. I would say you're going to get 20 to 30 minutes of general bashing out of a pack like that. That being said there's also a lot more room in the tray for something bigger.
@@scottssrrc1900 Yeah I think a 2200 should fit. It's really nice that they made the battery tray an actual decent size. A lot of these small cars are really only designed to hold the battery that comes with them and that's annoying
Unfortunately I don't think it's available. I ordered it along with every other optional part during a very short time when they were up on the horizon website. They were then taken down and I only received this part. They said everything else is on back order and I have no idea when it will be available.
@@DoRC With a quick google search, a rc shop's website edsrc shows in stock so I tried puttin in an order and we will see what happens hah. If nothing else I'll just slap the new esc ontop of the old one for now. Love the videos btw, I recomend finding new spots to bash :).
@adamneff1600 nice! Yeah there aren't too many options around here and I'm not really able to travel very far due to personal reasons. It kind of is what it is. I hope you're able to get the mount. My alternative was probably going to be to gut the ESC and just use it as the mount.
Awesome vid, i went with the cheaper rout using the king val system. Its an absolute rocket with a 4600kv brushless motor combo. It stays cooler even without a heat sink on 2S. But definitely needs a fan or at the very least a heat sink for 3S. Damn thing hits 47mph. Anyone find that this mod creates a lot of heat. And how do you keep it cool. Unfortunately my ecs didn't come with a fan on it nor the motor anyone know of a heatsink for a 24mm motor.
That's hard for me to judge because I have not had a Gorgon. That being said the grom is very small and is going to be limited to bashing in areas that have terrain that is suitably small enough for it. The Gorgon won't have those limitations so I would base my purchase on where you're planning on bashing.
What are the capacitors you’re using? Also, you mentioned in your original video that you would list all of the items you used but where is that parts list in your description?
The capacitors are just the ones that come with the 10 BL60 ESC. I go over the parts I used in detail at the end of the video. Essentially it's just the 10 BL60 ESC, the adapter shown in the video, the motor that I show a screenshot of the Amazon listing for in the video and your receiver of choice. Thanks for watching!
These are not plastic differentials they are metal. You didnt notice when you pulled the center plate? They come filled with grease but you can use diff fluid in them to tune as well. Filled ones are an optional part and aluminum center shaft too.
The ring and pinion are metal but the internal diff gears are plastic. The diff isn't sealed as the split in the middle has no gasket. The upgrade ones are built differently and I'm assuming where the meet the ring gear will have a gasket so they will actually be sealed. No one knows for sure yet but I'm assuming they will also have metal gears inside.
@DoRC I see. I was going off of the exploded view they looked no different than the 3s differentials. But now looking at the upgraded ones I can see the difference now
I forgot 2.3 2.0 different. Tricky with upgrading these little guys sometimes, where to find 2.0 pinion gears ? They all have same tooth counts , I stuffed 380 sized motor in mini t so I can gear high but than room and flexing became a issue
Interesting on the speed on 2S. I put a 16BL30 with a 2440 (so no stock heatsink) 4600KV motor in my Typhon Grom and it's about as fast on 2S as you show the GG on 3S w/3800kv. I haven't put my GNSS on it yet, but 800kv shouldn't be that much faster.
@Jeckler hmm. Who knows could be gearing could be KV difference in how much room we have to run battery etc. I don't really do much speed running so usually I'll take it out hit the throttle and whatever happens happens. I don't spend a lot of time trying to find tune things so I'm sure I rarely get the absolute most speed out of anything that I run
Good that you don't need to swop the steering servo! Really on the fence between buying this or MJX. Our local hobby shop will have MJX parts on stock in the very near future. However an Arrma platform which is ridiculously easy to work on is also a big advantage. And the same hobby shop is also an Arrma dealer. Decisions decisions 😵💫. What do you think?
Speedwise yes it competes now but handling in My opinion at least is way better. The MJX cars that I've used tend to be pretty sloppy and a Grom really has them beat there. It's also much easier to work on but not only matters if it breaks :-) Don't get me wrong The MJX cars are really good and I've been enjoying their little 114th scale monster truck that ripped off the X-Max body mount. Definitely fun and personally I think it's better than The HB 14.
@@DoRC It needs to be it's likely more expensive and from a bigger company with better quality parts but time will tel that the brushless grom can survive a few years...
@@maszkalman3676 Yeah so far the differential outdrive cup seems to be the big weak point. I have the all metal diffs on pre-order so hopefully I'll get them soon
Glad you enjoyed and welcome! I don't normally make videos following quite the incredibly hectic schedule I have for the last month but we usually put out one or two a week :-)
It is! I didn't realize it had that extra space under the drive shaft cover. Thanks for the info! just got 3 new batteries. Two zee amazon specials, and a gens ace. The original is crap hah. Have mine upgraded with a 1:10 sport ready 10BL60 HW Quicrun, and a brushless motor. Just got it programed finally and calibrated properly tonight. Its almost doing standing backflips on 2S LOL. Thanks again@@DoRC !
I managed to order all of the optional parts in apparently the hour that they accidentally had them on their website and they shipped me that single part. Everything else is back ordered and everything else is gone off the site. I asked them about it today and they said they haven't gotten the stuff in and it'll ship when it does come in. Unfortunately that part is just unavailable currently. I haven't seen a single other person say they got it so maybe I'm the only person in the world. Not sure.
The stock ESC which is the thing that powers the motor is only compatible with brushed motors. Because of this you need to also use a brushless ESC. Unfortunately the stock receiver is built into the ESC on this car so the receiver also needs to be replaced.
@DoRC For sure getting the upgraded diffs you featured in your video, and the CVDs. Shocks.? They look good but you can't see them with the body on, so probably not. Unless I break one.
@@robertshelton2605 Yeah the shocks look beautiful and they really are nice but functionally I don't think they're much different from the plastic ones.
I made a community post about being able to 3D print one, some people have modified their existing ESCs to become mounts for the new ESC and someone has one listed on eBay though I'm not sure if it's any good or not. Hope that helps!
I got one! These are so fun. 🔥 keeping it stock for now. More than enough indoors. Seriously, I hope they do more 18th scale stuff. I think they at least have plans with how some parts are listed for this currently. The big question is, can the grom survive me😂
@DoRC I'll probably go brushless next summer along with other upgrades. Then get another brushed version for winter again 😁 my poor outcast build just got put on hold.
I listed all out at the end of the video. It's basically just a 10 BL60 ESC, the adapter plate, the motor I showed a screenshot of from Amazon and receiver of your choice.
I don't normally do linking because links always end up becoming invalid but I think I described the motor in the video so if you just look that up you should be able to find it on Amazon.
It's been a long time since I thought about that car. I think I bought one they first came out in 2010 maybe. Unfortunately it's been long enough now that I don't really remember anything else about it.
I got it on Amazon. I'm actually going to be doing a whole video on it, modifying it to be better and giving one away that I already modified very soon!
@@miguelgomez9325 just go on Amazon and look up no cry electric screwdriver. You'll see the one I use in my videos. I try to avoid doing links because they always end up expiring and then people 6 months from now say that there's a link not working and I have to hunt for it etc :-)
Don't mean to be that guy and correct you but the little truck has metal diffs not plastic ones. May not be the toughest metal, they look similar to the diffs in the latrax Teton but nonetheless they are metal! Overall great video bro! And thank you!
I just pulled one of my differentials apart again to verify and at least on my example the internal differential gears are plastic. The outer ring and pinion gears are metal but not the ones inside. The internal differential gears are a black glass fiber reinforced nylon..
@bennovak4182 the diffs are not metal. The drive train is though. Arrma will have optional metal diffs coming but the ones that come with the truck are plastic.
I would say the ideal brushless motor for this truck is probably the HobbyStar 24x35mm 4500KV on 2S LiPo. 3S is obviously too much and that was on a 3800KV motor.
To be honest with you I'm not sure if there is a more ideal motor than the one that's in mine. It's got plenty of power on 2S and stays nice and cool. The only concern is longevity but I don't think hobbystar would really be any different there
@@DoRC True well HobbyStar tends to be pretty decent. However I came across a Hobbywing system that would be ideal. I thought they only had a tiny 20x30mm motor option but thats under EZRun 1/18th scale. Under QuicRun 1/16th scale there is a 16BL30 combo that includes a 24x35mm 4500KV option. Remember that bad quality amazon motors have such loose tolerances that a smaller brand name motor can easily be more powerful. I think the HW 24x35 SL 4500KV would blow that motor away in acceleration AND top speed especially with that oversized 10BL60 ESC powering it.
@wallacengineering8096 Not sure of 2435 motor would stand a chance against a 2838. 2838 is a lot bigger than 2435. Even if the 2435 were higher quality I still think it would be less powerful just cuz of how much smaller it is.
I just get lucky down here and pick This Grom today .. Quick question where can I find that servo mount pate I tried every where the part number dont show anywhere at all ?
Unfortunately it currently doesn't seem to available. I ordered pretty much every option part during a short window when they were listed on horizon's website. They sent me the adapter plate and nothing else. Since then it's all been removed and I was told everything's on pre-order.
Unfortunately they aren't currently available. I ordered mine when they were first listed on the site and I don't know why I got it but it doesn't seem like very many people did.
@@colerippeon3903 You're welcome. Yeah hopefully they'll have it listed again soon. I asked them and they said they didn't know when they were getting them in.
@@DoRC OK thanks again. That's the pitch LC racing uses can get one from Warren rc. But the more I think about it l will probably just grab a motor with a 2.3 shaft. I have the MJX Hyper Go 14210 it's ok but it has plenty of budget rc qualities. Sloppy steering sloppy axle carriers the hardware is horrible and it is nightmare to work on. Arma are the large scale trucks l run. I love them . So I am going to get the Grom for my backyard basher.
@markschwing3850 Yeah if it's available I would recommend the one from Amazon that I used. I wasn't too sure about it to begin with but I've got several packs through it now and it's holding up great and feels like a very appropriate size and KV for the truck.
Yes and at this time unfortunately it does not appear to be available. I don't know how I was so fortunate to get it but they took all the upgrades back off the site and they said everything is back ordered when I contacted them.
@seanconnolly2179 Yeah given the upgrade parts they have I would not be surprised to see an EXB version of this same vehicle in the future. Pretty much all they have to do is take this car stick all the upgraded parts in it put a brushless system in and it's an EXB.
@@RcPlayer-tt2vwI haven’t gotten the truck yet , but I purchased a castle creation brushless motor and esc funny I purchased upgrades before buying the truck lol i😂
Definitely a fun little car! I run these little guys more often than I do my big cars just because of where you can run them. I can throw one of these in my truck and literally go bash anywhere. Unlike big RCs which can be intimidating to other people these just look like little toys and no one gives you a second glance.
@DoRC I city bash and live in a studio apt so these are perfect for me. Bring my TLR typhon out on 4S later today in hopes I find a semi empty park to use.
I showed a listing of the motor on Amazon at the end of the video, you can get the ESC lots of places as it's been out a long time. Unfortunately the adapter plate that I also showed at the end of the video does not seem to be currently available and Horizon can't give me an answer as to when it will be available.
I just started hunting around on Amazon for something I thought would work. I actually bought it before I even got the car. I think I was kind of lucky that it was the right KV because there weren't very many options with 2.3 mm shafts in that size.
As far as the motor goes, you can get a 0.5 mot pinion to fit a 1/8 shaft. I bought one with a 3mm bore and just hit it with a 1/8 drill bit and it worked perfectly. Avoids shearing the shaft like I’ve seen a lot of people do.
Any mods 0.5 gear will work. The stock motor shaft size is 2.3 mm but if you use a different motor it would need to be whatever size that motor shaft is.
@IronOre33 What exactly are you trying to accomplish? You'll need a different motor mount to run a bigger pinion gear as the motor mounts are gear specific and not adjustable. I don't think other mounts are available at the moment.
How would I have mathematically calculated if a system that I had not installed yet was going to be faster or if it was going to damage the differentials? The specific formula would be helpful :-)
@@DoRCzing! Math guy has no answer because he just wanted to feel superior to someone with mechanical talents. YT comments sections remind me of when I win an argument with my mom, she just stops talking. The end. You win, math loses.
It's a motor, because it's electric. An "engine" involves either steam or internal combustion with related pressure\timing based operation. TLDR: motors simply spin, or spin a shaft, while an engine has a completely different operation based on piston movement, etc...
Can you pop wheelies easier with the upgrade ? Versus the brushed stocked ? I like to pop a lot of wheelies I just want a little mini bashed I have a cheap motor I can swap and esc I want one I also have the actual granite on layaway lol I’m just obsessed with rc at this point I love your videos bro!
@@DoRC thanks for getting back to me ! I ended up doing the conversion except left the sec on as the 2nd esc installed hey it works but I love this truck who would have known a little truck could be so much fun !
Update the upgraded differential is a must ! This thing runs beastly now even on 2s no need for me to experiment anymore and just enjoy enjoy this bad boy just need an upgrade at esc but the cheap one I got will last for however long it decides too lol
Unfortunately I don't think you're going to be able to for a while. I got really lucky and ordered mine when they had the parts listed for a very short period of time on the horizon site. They since took them down and I don't know when they're coming back up again.
The other day I drove an mjx of a friend of mine and it was horrible. Only good for jumping. I couldn't take a single turn without spinning around. Is this a better handling veachle? I don't care much for upgrading. The total cost it will be similar to a 1/10 veachle. Also the built quality of the mjx looked terrible. Tiny screws fell of after a few minutes of play. I know the quality of arrma I have a typhoon 3s, I am looking for a cheaper monster truck for my son so we can bush around together.
I think this is the best handling out of the box Little vehicle that I've had. That being said I'm not sure it's going to be a lot of fun bashing with a typhon just because the Typhon can go places this wouldn't be able to. As long as you keep it to sand gravel concrete and really short sparse grass it should be okay but it is still a very small car and has the limitations of being a very small car.
Turns on what you mean. I'm sure you can make this car go faster or any car go faster with enough power and time. That being said these little cars tend to get pretty squirrely at high speed so I think something like this has a reasonable practical top speed of probably 40.
I would love to see you run this on 2S and 3S with a gyro. I wonder how well that would help keep things under control. For sure going to get one and let my 3 year old drive it in the basement.
I'm sure it would make a big difference. It's not that crazy uncontrollable even on 3S. It's a handful but it's still doable so I would imagine a gyro would make a big difference.
Just as I would expect from an all plastic Arrma… They are tough as nails… 👍🤘 No clue why it didn’t come factory brushless… pretty dumb on their behalf…
I'm going to get two reasons. First one is to save money and keep the price down and the second one is that they're probably going to come out with an EXB brushless version down the road. If you look at the option parts they have available they all kind of come together to make an EXB version.
It is a little interesting to me that they didn't go slightly larger. This is smaller than most of the competition in the same range and whereas it's a lot of fun and actually handles very well for the size I think a little bit bigger would have been better.
I bought it on Horizon. Unfortunately they took all the upgrades off their site shortly after I ordered it and I honestly don't know how many of those they shipped out but it appears as though you can't currently get it.
They just don’t want to ship stuff unless the profits high 😂 wth going on with horizon , talking to LHS they just don’t care because they’re stuck with the program they’re using
The only downside with this is the plastic diff gears (over time). Honestly it's only contender at this size and price point is the HBX 18559a which does have all metal gears and comes brushless. But Arrma likely wins due to part availability and how easy it is to swap...well everything.
Well fortunately they're going to have upgraded diffs available. I actually was able to pre-order a set of them when they were on the horizon web page. They have since been taken down but the description said they were going to be metal and sealed so that should be a sweet upgrade. As far as the plastic differentials are concerned I'm sure they will not last forever at 3S but I think on 2S with a modest system they should be fine.
It wont sell well. People will still get the chineses ones most of the time. A 1/18 scale rc is not a serious rc for inside or outside. Way too small for the suspension to work properly. Maybe a 1/16 with bigger tires would have somewhat worked but 1/18 doesnt do it for me. The only small scale rc i see having its place is mini cralers because of the mini tracks you can make and run on
@@EXTREMERC416 I'd have to disagree with you. I've been running these small scale trucks for many years now and I run them just as much if not more than my bigger trucks. These are great for just throwing in your vehicle and taking literally anywhere. Because It looks like a little toy no one will give you a second glance no matter where you are. You might be surprised about how well they work too This one's very well tuned and the suspension works just fine :-)
I never had any issues with arrma plastic diffs until you use a LWB and 4s or terrible driving on 4s I guess , possibly the quality has gone down a notch and that’s why , my granite had 100s of packs till finally broke gear and that’s wear metal would’ve been done also , but the brcc I went through a couple using a normal amount . The brcc was after horizon so not sure , that truck broke far more overall , rcs funny like that , can have different experiences
Depends on what your goals are. The MJX cars are cool but build quality on this is higher and both upgrades and spare parts are probably going to be easier to get. This also handles out of the box better than any other small vehicle that I've had short of maybe the 14mt but that's a much larger vehicle.
I came through the other video, thank you, your reviews are very good, you observe and talk about everything and the best thing is that you disassemble the parts to observe well what it contains, additionally you show and express the part numbers and name to be able to get and buy them
Glad you enjoy and thanks for watching :-)

Cool release from Arrma. We’ve been asking for a micro for ages. Hopefully if these sell well, we’ll get a 1/20th outcast brushless with full metal drivetrain. Would love a living room basher that has quick rotational capability for backflips off the little orange ramps
Yeah it's definitely sweet!
mini outcast would be cool. or even a tiny infraction
@lyst5946 Yeah I'm looking forward to what they come up with next!
Thank you for the video. I just did the exact same setup on my granite grom, minus the rx and tx. Can’t wait to test it on 2s tomorrow. Hopefully my Arrma all metal diffs hold up.
Yeah the diffs should hold up fine.
Awesome 😎 That thing looks great on 2s Lipo and although a little sketchy, and out of control at high speed on 3s, it does look fun at 3s. I think along with the Gorgon, this may be another home run for Arrma. Such low prices on these two new durable, fun bashers, will surely have a ton of these under Christmas trees this year! I really don’t need the Grom since I have the full 4x4 3s granite.

Le gorgon en 3s c'est juste fantastique 😂😂 et super solide
Very cool, suprised how stable it is, especially on jumps, lands nicely, great video 👌
Yeah it's surprisingly well tuned out of the box. For how small it is it actually handles better than some of the 114th and 1/16th scale trucks.
Sorry about some of the bad camera angles I just got a new camera mount and I'm still getting used to it.
@@DoRC all good 👍only issue here in the uk its almost $160, for me the mjx range works out better value. Still tempted to buy ine though 🤔
@RCvapor Yeah I think by the raw numbers there are better values out there especially given that this is brushed but I also think this car will have a lot of potential in the long run for upgrades and mods.
Oh wow well thanks for clarifying that. I work in a hobby shop and I've been using that as a selling point for these Groms which are flying out the door! They claim they have metal diffs. So thank you for the clarification. Keep up the good work bro.
Yeah Arrma is really good and making things sound just a little bit better than they are in their descriptions. They don't quite lie but they do carefully worship things.
@@DoRC They advertise it " 4WD transmission with robust metal gears " ,
that is nearly lying as diff gears are plastic.
I dont appreciate when a company takes people for idiots.😡
@@Madprax I completely agree and this is far from the first time they've done something like this. The people who write these listings are very good at implying things that aren't true whille not quite crossing the line to overt false advertising. It's kind of like with the new 8S EXB RTR. If you read the description it appears as though there's all kinds of new updated pieces in the car when the reality is it's just the old EXB roller with electronics in it and slightly updated tires.
I have found that they will specifically advertise anything that's good so if it doesn't specifically say something like "metal internal differential gears" You can bet they're probably plastic.
Wow I just looked at the specs and it says full metal, interesting that there is plastic diff gears
@@VetteWay2Fast Yeah it's not just the differential gears. The output cups on the diffs and the stub axles are also plastic. Arrma as always been good at not quite false advertising like that.
Awesome video again dude. I'm excited to throw some Hyper Go electronics in one of these!
Thanks :-) let me know how it goes!

@@DoRC Oyyeee Aluminium Cover And worth to do to the Big Rock 3s V3 converted to 4s.Almoust all Arma parts fit's perfect.
Impressived the plastic diffs handled the brushless
Yeah the plastic output cups are the weak point but they do seem to hold up well to stock power and even a bit of extra power
Great man! Did you have to do full throttle when doing double backflips?
I don't remember. This has since been sold but I don't think I did.
interesting. multiple mounts, so they'll all be fixed size i reckon?
Yes they will all be for a specific gear combination. They had them all listed on their site but when they took all of the option parts down they took those down as well. There was a pretty good selection of them though so you should be able to get whatever you need.
I search other brand of motor of this size with 2.3mm shaft but no one make, I finally order the same motor. Thank you :)
Glad to help. I can't really speak to the longevity of the motor because I'm not familiar with the brand but so far it seems to be working well.
Hey Kenny ,cool vid . I couldn t read the motor can with the glare...I m guessing 4500kv 2435? Thanks
Toward the end of the video I actually show a picture of the exact motor and it specs on Amazon. It's 3,800 KV.
It's neat but for me it's not going to replace the HBX 16889a pro as my recommendation for new folks and kids. Parts are everywhere where it's marketed as like 8 different brands and it''s already brushless, quick, and still cheaper.
The 16889 pro is a fantastic truck. Definitely what I would still recommend to most people so far. I'll probably end up sticking with the Grom just because it's going to have a lot of upgrade options and I love upgrading especially when the upgrades are small and cheap :-)
I have snapped two motor shafts on my Granite Grom. Running the Mamba Micro ESC and snapped the Castle motor shaft and a Amazon motor shaft. What am I doing wrong? Pinion gear? Can't be too much power, I ran the same setup on my Losi Mini B, no problems. Mayby the tires are too big? Never had this problem on any RC car before.
From what I've heard the smaller diameter output shaft on the small micro motors can't handle the stress and end up breaking.
@@DoRC What setup would you recommend? I don't won't to sale my truck or put it on the shelf. Plus I just got a Typhon Grom I want to go brushless.
might just get the Associated 14B
Oh man I want one of these! Looks like it would be a perfect candidate for my spare Castle Mamba micro Pro! Had the combo from my old ECX 1/18 Ruckus but it would just destroy the gears. I would love to throw it in one of these and then compare it with my 1/18 HBX brushless monster truck
Yeah it's a pretty sweet truck!
That thing is so cute on 3s 🤣 he was trying so hard to bash on that power ! But he kept flipping and crashing haha
Yeah it's pretty much uncontrollable on 3S. Fun to mess with but not practical. Thanks for watching :-)
Great video, I learned a lot. Do have link fro the 3S battery? Thanks.
I don't and it's probably not the ideal battery anyway. I think I just grabbed something I had from my FPV quads. Best thing to do is just measure out the battery tray then jump on Amazon and find something that fits and fits your budget.
can we get a full parts list or links to all the parts for this upgrade plz and thanks
I detail it out at the end of the video but it's the keenso 3800 KV motor on Amazon, hobbywing 10 BL60 sensored ESC, the ESC plate adapter from Horizon and receiver of your choice.
I hit 42 on the same set up on 3s and never flipped... you have to take out the 4 spacers out of the shocks and also cut the front springs 1.5 rings shorter
Yeah I'm sure you can definitely go faster than I did. I was just showing what it can do with the out of the box setup. 42 is impressive!
I have a Hyper go P16 race buggy with some upgrades. All metal shocks. Upgraded spur gear, wheelie bar, upgraded steering servo,I greased the gears. Been running 2S brushless stock system. It's great. But I will be honest I think I could build one of these and it would come out better and handle a little better then the Hyper go.. 👀
I think especially once everybody starts making upgrades for these you'll be able to build it better than any of the other little cars available.
Just get an HBX 16889 pro ...100 bucks , no upgrade needed right out of the box .
It ll cost you 300 to get same equiped Grom . ( stupid to me )
@Madprax to get the exact same equipment list yes but I will say that my 16889 pro could not handle 3S brushless with just about the same system without immediately breaking. The Grom handled it well so, whereas the drivetrain doesn't quite have the same specifications, it seems to be at least as durable out of the box.
Awesome little ripper! :D
Yeah I think brushless 2S is definitely the way to go. It does handle 3S but it's also pretty uncontrollable. Brushless to us gives it just that extra bit of power that it needs.
Awesome video, i just purchased two of these today. Will definitely be changing to brushless in one of them. How much run time did you get out of the 2s shorty pack.
Not entirely sure. The 2S pack I ran in the video also included the speedruns so that's going to knock down the time a bit. I would say you're going to get 20 to 30 minutes of general bashing out of a pack like that. That being said there's also a lot more room in the tray for something bigger.
@@DoRC thanks for the fast response, I just ordered a couple ovonic 2s 2200 off Amazon should fit nicely
@@scottssrrc1900 Yeah I think a 2200 should fit. It's really nice that they made the battery tray an actual decent size. A lot of these small cars are really only designed to hold the battery that comes with them and that's annoying
2s definitely seems more appropriate 😆
That footage looks sped up up!
Yeah 2S is definitely the way to go!
@Do RC nice content, what would you choose out of this grom or MJX Hyper-Go 3S H14BM ?
Not sure. I actually am working on a video about that exact thing right now. Stay tuned it'll be out in a couple days :-)
@@DoRC I actually got a guy today wanting to swap my spare hyper go 14210 for his arrma grom which he upgraded to brushless o_0.
@@monkeytrident as long as the Grom is in good condition I'd go for it
Awsome video ya 3s looked crazy for that little truck haha hopefully today I get mine 😄
Yes In my opinion 3S is too much. 2s gives you a nice little extra boost while still being controllable.
@@DoRC heck ya
@@bfam8056 Thanks for watching :-)
@DoRC got mine today so fun in the house made a ramp out of a pizza box haha
@bfam8056 Nice! That's one of the great things about these little cars. You can bash some pretty much anywhere and basically anything is a ramp :-)
where did you get the mount ARA320753? Is it available to purchase anywhere online?
Unfortunately I don't think it's available. I ordered it along with every other optional part during a very short time when they were up on the horizon website. They were then taken down and I only received this part. They said everything else is on back order and I have no idea when it will be available.
@@DoRC With a quick google search, a rc shop's website edsrc shows in stock so I tried puttin in an order and we will see what happens hah. If nothing else I'll just slap the new esc ontop of the old one for now. Love the videos btw, I recomend finding new spots to bash :).
@adamneff1600 nice! Yeah there aren't too many options around here and I'm not really able to travel very far due to personal reasons. It kind of is what it is.
I hope you're able to get the mount. My alternative was probably going to be to gut the ESC and just use it as the mount.
I bought the same motor, do i have to change out the esc or will the stock one work?
You need to change out the ESC. The motor in the video is a brushless motor and the stock ESC is a brushed ESC.
@@DoRC thank you
@@professional_hater885 You're welcome the ESC in the video is a good one to go with as well
Awesome vid, i went with the cheaper rout using the king val system. Its an absolute rocket with a 4600kv brushless motor combo. It stays cooler even without a heat sink on 2S. But definitely needs a fan or at the very least a heat sink for 3S. Damn thing hits 47mph. Anyone find that this mod creates a lot of heat. And how do you keep it cool. Unfortunately my ecs didn't come with a fan on it nor the motor anyone know of a heatsink for a 24mm motor.
I really only run mine on 2S so haven't had much issue with heat. Honestly for me 3S is just too much.
Grom or Gorgon? It's about the same amount of money, which one would you choose?
That's hard for me to judge because I have not had a Gorgon. That being said the grom is very small and is going to be limited to bashing in areas that have terrain that is suitably small enough for it. The Gorgon won't have those limitations so I would base my purchase on where you're planning on bashing.
Great Video!
Glad you enjoyed thanks for watching :-)
What are the capacitors you’re using? Also, you mentioned in your original video that you would list all of the items you used but where is that parts list in your description?
The capacitors are just the ones that come with the 10 BL60 ESC. I go over the parts I used in detail at the end of the video. Essentially it's just the 10 BL60 ESC, the adapter shown in the video, the motor that I show a screenshot of the Amazon listing for in the video and your receiver of choice. Thanks for watching!
These are not plastic differentials they are metal. You didnt notice when you pulled the center plate? They come filled with grease but you can use diff fluid in them to tune as well. Filled ones are an optional part and aluminum center shaft too.
The ring and pinion are metal but the internal diff gears are plastic. The diff isn't sealed as the split in the middle has no gasket.
The upgrade ones are built differently and I'm assuming where the meet the ring gear will have a gasket so they will actually be sealed. No one knows for sure yet but I'm assuming they will also have metal gears inside.
@DoRC I see. I was going off of the exploded view they looked no different than the 3s differentials. But now looking at the upgraded ones I can see the difference now
@ralphhondaman Yeah it would be nice if the stock ones were metal but unfortunately they're not.
Hobbywing have a motor with the shaft 2.3mm and for information to any person. The 2440 brushless motor has 2.3mm, 2435 have 2mm shaft
Nice! I'm sure there are a bunch of options this was just the only one I could find on Amazon and get short notice :-)
I forgot 2.3 2.0 different. Tricky with upgrading these little guys sometimes, where to find 2.0 pinion gears ? They all have same tooth counts , I stuffed 380 sized motor in mini t so I can gear high but than room and flexing became a issue
Maybe Amazon?
Interesting on the speed on 2S. I put a 16BL30 with a 2440 (so no stock heatsink) 4600KV motor in my Typhon Grom and it's about as fast on 2S as you show the GG on 3S w/3800kv. I haven't put my GNSS on it yet, but 800kv shouldn't be that much faster.
How are you checking the speed if you haven't put the GPS on it?
@@DoRC My highly calibrated eyeballs, or course. :) I just went out to check. I got 34MPH out of it.
@Jeckler hmm. Who knows could be gearing could be KV difference in how much room we have to run battery etc. I don't really do much speed running so usually I'll take it out hit the throttle and whatever happens happens. I don't spend a lot of time trying to find tune things so I'm sure I rarely get the absolute most speed out of anything that I run
Good that you don't need to swop the steering servo! Really on the fence between buying this or MJX. Our local hobby shop will have MJX parts on stock in the very near future. However an Arrma platform which is ridiculously easy to work on is also a big advantage. And the same hobby shop is also an Arrma dealer. Decisions decisions 😵💫.
What do you think?
Not sure. I'm actually making a video on an MJX truck right now that aims to answer that very question. Stay tuned!
What size motor did you use?
It's a 380 size motor that I got on Amazon. I have a screenshot of it at the end of the video.
@@DoRCso 28**. I read in the comments 38. Will that be max length?
I found a hobbywing combo for 1/18 1/16 with 30a ESC and 2838 3800kv motor. Would 30a be too little or did you just go overkill on the ESC?
Turned that into a lil ripper for sure!
Yeah it's pretty uncontrollable on 3S but 2S with that brushless system is definitely the sweet spot.
Yes you do G💯
Thanks for watching!
Yes it did get better and now it can compete with the mjx cars and i'm not gonna lie on the sand it looks cool....
Speedwise yes it competes now but handling in My opinion at least is way better. The MJX cars that I've used tend to be pretty sloppy and a Grom really has them beat there. It's also much easier to work on but not only matters if it breaks :-) Don't get me wrong The MJX cars are really good and I've been enjoying their little 114th scale monster truck that ripped off the X-Max body mount. Definitely fun and personally I think it's better than The HB 14.
@@DoRC It needs to be it's likely more expensive and from a bigger company with better quality parts but time will tel that the brushless grom can survive a few years...
@@maszkalman3676 Yeah so far the differential outdrive cup seems to be the big weak point. I have the all metal diffs on pre-order so hopefully I'll get them soon

Sweet I'll be looking forward to them
What kv is that brushless motor?and I can’t find the part number 🤷🏽♂️
3800 KV and unfortunately that adapter is not currently available.
No issues fitting that OvonicFPV in the battery tray?
Not at all. The battery tray is surprisingly generously sized.
It is! I didn't realize it had that extra space under the drive shaft cover. Thanks for the info! just got 3 new batteries. Two zee amazon specials, and a gens ace. The original is crap hah. Have mine upgraded with a 1:10 sport ready 10BL60 HW Quicrun, and a brushless motor. Just got it programed finally and calibrated properly tonight. Its almost doing standing backflips on 2S LOL. Thanks again@@DoRC !
The servo mount isn’t available anywhere. How’d you get it?
I managed to order all of the optional parts in apparently the hour that they accidentally had them on their website and they shipped me that single part. Everything else is back ordered and everything else is gone off the site. I asked them about it today and they said they haven't gotten the stuff in and it'll ship when it does come in. Unfortunately that part is just unavailable currently. I haven't seen a single other person say they got it so maybe I'm the only person in the world. Not sure.
I have a hobbywing 16bl30 in mine it rips
Yeah the 10 BL60 is a little bit of overkill. It's what I had on the shelf :-) stays nice and cool though!
So where is the Gorgon? Cant believe its out of stock through Christmas!
Yeah they've been pretty popular. Maybe check your local hobby shop. They might have some in stock.
@@DoRC Lol like I told you local hobby shops dried up in Queens NY
@@rccarsandmusic2641 oh sorry. I talked to a lot of people so sometimes it's hard to keep track of exactly who said what.
@@DoRC Yeah me from FB messenger
@rccarsandmusic2641 gotcha.
Can I just put that kv brushless motor in there while leaving my existing spectrum transmitter etc..?
The stock ESC which is the thing that powers the motor is only compatible with brushed motors. Because of this you need to also use a brushless ESC. Unfortunately the stock receiver is built into the ESC on this car so the receiver also needs to be replaced.
I’m so glad nobody on my street but me has an Rc car. I would hate for neighbors to hit my White Ford Ranger with their Arrma from.
Don't worry that truck's seen a lot worse than my little RC car :)
I put the Mamba Micro combo in my Grom.... too much power. But if you dail back the power it's cool.
Yeah the combo that's in this one is too much power as well especially on 3S but it sure is fun :-)
@DoRC For sure getting the upgraded diffs you featured in your video, and the CVDs. Shocks.? They look good but you can't see them with the body on, so probably not. Unless I break one.
@@robertshelton2605 Yeah the shocks look beautiful and they really are nice but functionally I don't think they're much different from the plastic ones.
🚨 Hello, good morning, I'm back again, I'm trying to look for the servo mounter and I can't find it anywhere online or in stores, where can I get it?
I made a community post about being able to 3D print one, some people have modified their existing ESCs to become mounts for the new ESC and someone has one listed on eBay though I'm not sure if it's any good or not. Hope that helps!
@@DoRC ok thanks horizon already has it and bought it
@edgardovera6490 Yeah they came back into stock a couple days ago.
I got one! These are so fun. 🔥 keeping it stock for now. More than enough indoors. Seriously, I hope they do more 18th scale stuff. I think they at least have plans with how some parts are listed for this currently. The big question is, can the grom survive me😂
As long as you're keeping it stock I bet it will. I think it'll be pretty much indestructible with stock power
@DoRC I'll probably go brushless next summer along with other upgrades. Then get another brushed version for winter again 😁 my poor outcast build just got put on hold.
@@Macgyver46 I definitely get that feeling. I probably got 15 different projects on hold right now.
Sorry did you had a parts list for this conversion? Cheers
I listed all out at the end of the video. It's basically just a 10 BL60 ESC, the adapter plate, the motor I showed a screenshot of from Amazon and receiver of your choice.
Brilliant thank you 😎👍
@@Shnoofrc71 You're welcome let me know how it goes!
What type of electric screw driver do you have?
Nocry of Amazon. Silly name but really good screwdriver
What brushless motor did you buy? Got a link
I don't normally do linking because links always end up becoming invalid but I think I described the motor in the video so if you just look that up you should be able to find it on Amazon.
Reminds me of the Duratrax Mini Quake
It's been a long time since I thought about that car. I think I bought one they first came out in 2010 maybe. Unfortunately it's been long enough now that I don't really remember anything else about it.
Cool. Just got a new follower. Lol also quick question where did you buy your electric hex tool
I got it on Amazon. I'm actually going to be doing a whole video on it, modifying it to be better and giving one away that I already modified very soon!
@DoRC cool can I have a link to it please. I would like to purchase it loo
@@miguelgomez9325 just go on Amazon and look up no cry electric screwdriver. You'll see the one I use in my videos. I try to avoid doing links because they always end up expiring and then people 6 months from now say that there's a link not working and I have to hunt for it etc :-)
Don't mean to be that guy and correct you but the little truck has metal diffs not plastic ones. May not be the toughest metal, they look similar to the diffs in the latrax Teton but nonetheless they are metal! Overall great video bro! And thank you!
The spider gears are plastic it seems.
I just pulled one of my differentials apart again to verify and at least on my example the internal differential gears are plastic. The outer ring and pinion gears are metal but not the ones inside. The internal differential gears are a black glass fiber reinforced nylon..
@bennovak4182 the diffs are not metal. The drive train is though. Arrma will have optional metal diffs coming but the ones that come with the truck are plastic.
Yeah I just pulled one of mine apart again to verify and they are definitely plastic
Yes after seeing his comment I pulled mine apart again and it's definitely plastic gears inside
I would say the ideal brushless motor for this truck is probably the HobbyStar 24x35mm 4500KV on 2S LiPo. 3S is obviously too much and that was on a 3800KV motor.
To be honest with you I'm not sure if there is a more ideal motor than the one that's in mine. It's got plenty of power on 2S and stays nice and cool. The only concern is longevity but I don't think hobbystar would really be any different there
@@DoRC True well HobbyStar tends to be pretty decent. However I came across a Hobbywing system that would be ideal. I thought they only had a tiny 20x30mm motor option but thats under EZRun 1/18th scale. Under QuicRun 1/16th scale there is a 16BL30 combo that includes a 24x35mm 4500KV option. Remember that bad quality amazon motors have such loose tolerances that a smaller brand name motor can easily be more powerful. I think the HW 24x35 SL 4500KV would blow that motor away in acceleration AND top speed especially with that oversized 10BL60 ESC powering it.
@wallacengineering8096 Not sure of 2435 motor would stand a chance against a 2838. 2838 is a lot bigger than 2435. Even if the 2435 were higher quality I still think it would be less powerful just cuz of how much smaller it is.
@@DoRC Possibly. It would be interesting to see the difference for sure
@@DoRCwhat motor are you running ?
Do you say what the ESC/motor replacement is?
Yes I discuss that at the end of the video.
What's the servo mount?? Been struggling to figure that part out
The part number is shown at the end of the video. I believe they are available online and you can just Google that part number.
I just get lucky down here and pick This Grom today .. Quick question where can I find that servo mount pate I tried every where the part number dont show anywhere at all ?
Unfortunately it currently doesn't seem to available. I ordered pretty much every option part during a short window when they were listed on horizon's website. They sent me the adapter plate and nothing else. Since then it's all been removed and I was told everything's on pre-order.
Did the stock pinion workout in the Long run?
Yup. Still in there!
@@DoRC I've went through three brushed motors on this damn thing. Was using your video as a reference to go brushless.
u think the spektrum 2 in 1 would work well with this?

yeah i also did notice its a more like 280 sized motor more for like a losi mini b.@@DoRC

@@DoRC Ok. Thank you for the info!
@@colerippeon3903 You're welcome. Yeah hopefully they'll have it listed again soon. I asked them and they said they didn't know when they were getting them in.
Hey what is the pinion pitch and how many teeth does the pinion have on this little truck. I want to use a motor with a thicker shaft then 2.3mm.
It's mod 0.5 and I think it's 15 tooth but you can look at the exploded view diagram to verify that.
@@DoRC OK thanks again. That's the pitch LC racing uses can get one from Warren rc. But the more I think about it l will probably just grab a motor with a 2.3 shaft. I have the MJX Hyper Go 14210 it's ok but it has plenty of budget rc qualities. Sloppy steering sloppy axle carriers the hardware is horrible and it is nightmare to work on. Arma are the large scale trucks l run. I love them . So I am going to get the Grom for my backyard basher.
@markschwing3850 Yeah if it's available I would recommend the one from Amazon that I used. I wasn't too sure about it to begin with but I've got several packs through it now and it's holding up great and feels like a very appropriate size and KV for the truck.
@@DoRC what size and kv is the motor. Seems like a very suitable motor you have chosen.
@markschwing3850 It's 3,800.
10bl60? I’ve been using a 16bl30
Time to step up the game :-)
Where is the full list??
I detail what I used at the end of the video:)
Is that a upgrade servo mount specifically for the Grom ?
Yes and at this time unfortunately it does not appear to be available. I don't know how I was so fortunate to get it but they took all the upgrades back off the site and they said everything is back ordered when I contacted them.
@@DoRC that’s good because this tells us they are considering other power options in the future 👍👍
@seanconnolly2179 Yeah given the upgrade parts they have I would not be surprised to see an EXB version of this same vehicle in the future. Pretty much all they have to do is take this car stick all the upgraded parts in it put a brushless system in and it's an EXB.
Where did you get yours ? I thought these were in house only
@@RcPlayer-tt2vwI haven’t gotten the truck yet , but I purchased a castle creation brushless motor and esc funny I purchased upgrades before buying the truck lol i😂
Awesome. I'm definitely getting a few of these. I have no clue how to pay for em but yeah, I want one at least.
Definitely a fun little car! I run these little guys more often than I do my big cars just because of where you can run them. I can throw one of these in my truck and literally go bash anywhere. Unlike big RCs which can be intimidating to other people these just look like little toys and no one gives you a second glance.
@DoRC I city bash and live in a studio apt so these are perfect for me. Bring my TLR typhon out on 4S later today in hopes I find a semi empty park to use.
@Macgyver46 sounds like the perfect truck for it!
@DoRC while waiting for batteries to charge I'm looking at scrap materials to build a mini ramp for the Grom 🤣
@Macgyver46 Yeah for something that's small you don't need much. An old road sign and a block of wood or something like that will work :-)
Will this work on the typhoon grom?
Yep
Where could I get all the things he said?
I showed a listing of the motor on Amazon at the end of the video, you can get the ESC lots of places as it's been out a long time. Unfortunately the adapter plate that I also showed at the end of the video does not seem to be currently available and Horizon can't give me an answer as to when it will be available.
How did you find out about that motor?
I just started hunting around on Amazon for something I thought would work. I actually bought it before I even got the car. I think I was kind of lucky that it was the right KV because there weren't very many options with 2.3 mm shafts in that size.
As far as the motor goes, you can get a 0.5 mot pinion to fit a 1/8 shaft. I bought one with a 3mm bore and just hit it with a 1/8 drill bit and it worked perfectly. Avoids shearing the shaft like I’ve seen a lot of people do.
Good tip!
Can i have a link for a bigger pinion gear for this rc car
Any mods 0.5 gear will work. The stock motor shaft size is 2.3 mm but if you use a different motor it would need to be whatever size that motor shaft is.
@@DoRC im still new to rc so can you just give me any link for one
@IronOre33 What exactly are you trying to accomplish? You'll need a different motor mount to run a bigger pinion gear as the motor mounts are gear specific and not adjustable. I don't think other mounts are available at the moment.
@@DoRC im trying to accomplish higher speed but i am too scared to do what you did
@@DoRC because again, i am new at rc
Where exactly can I find this esc motor combo?
The ESC is a hobbywing 10 BL60 and the motor I got on Amazon. I think I showed a picture of it in the video. It's just a generic motor.

"i have no idea" .... if you knew math.. you would have an idea. 🤣
How would I have mathematically calculated if a system that I had not installed yet was going to be faster or if it was going to damage the differentials? The specific formula would be helpful :-)
Math gives you erectile dysfunction, it's been scientifically proven.
@@DoRCzing! Math guy has no answer because he just wanted to feel superior to someone with mechanical talents.
YT comments sections remind me of when I win an argument with my mom, she just stops talking.
The end. You win, math loses.
What about extra batteries
Not sure exactly what you're asking here.
What engine did you replace it with?
There's a picture of the Amazon listing for the motor at the end of the video it's just a generic motor that I found that would fit the bill.
It's a motor, because it's electric.
An "engine" involves either steam or internal combustion with related pressure\timing based operation.
TLDR: motors simply spin, or spin a shaft, while an engine has a completely different operation based on piston movement, etc...
Can you pop wheelies easier with the upgrade ? Versus the brushed stocked ? I like to pop a lot of wheelies I just want a little mini bashed I have a cheap motor I can swap and esc I want one I also have the actual granite on layaway lol I’m just obsessed with rc at this point I love your videos bro!
Absolutely! This thing pops wheelies like crazy on brushless
@@DoRC thanks for getting back to me ! I ended up doing the conversion except left the sec on as the 2nd esc installed hey it works but I love this truck who would have known a little truck could be so much fun !
Update the upgraded differential is a must ! This thing runs beastly now even on 2s no need for me to experiment anymore and just enjoy enjoy this bad boy just need an upgrade at esc but the cheap one I got will last for however long it decides too lol
@@DoRCthank you for videos bro I need to listen to you more and stop experimenting blindly lol if there’s a member section lemme know I’d love to join
@tonymartinez6974 just be careful I've seen a lot of those cheap Amazon ESC's catch fire.
nice 👌 love it 👌😀😀👍👍
Glad you enjoyed and thanks for watching :-)
Can't find the servo mount yet 😢
Unfortunately I don't think you're going to be able to for a while. I got really lucky and ordered mine when they had the parts listed for a very short period of time on the horizon site. They since took them down and I don't know when they're coming back up again.
@@DoRC thank you for the reply looks like I'll be cutting up my esc/servo mount for now.. Cheers
@wildcanuc Yeah at the moment I think that's the only option. Let me know how it goes
Does Arrma make a 1:18th senton or typhon? that would be awesome.
Not yet but there was a long wheelbase version of the chassis listed accidentally when they first released this so I suspect there will be one coming.
Kool truck ,but sucks you have to put brushless in it. That would be kool if they offered two options ,brushes brushless
Given the list of upgrades that I saw before they took them down I'm guessing that there will be an EXB version coming with brushless.
what motor and esc are you using?
Everything I used is listed at the end of the video:)
@@DoRC thx
will an 2835 motor fit?
I'm honestly not sure. The motor I put in there is pretty snug.
@@DoRC we can find out when my mjx mew4 breaks
The other day I drove an mjx of a friend of mine and it was horrible. Only good for jumping. I couldn't take a single turn without spinning around. Is this a better handling veachle? I don't care much for upgrading. The total cost it will be similar to a 1/10 veachle. Also the built quality of the mjx looked terrible. Tiny screws fell of after a few minutes of play. I know the quality of arrma I have a typhoon 3s, I am looking for a cheaper monster truck for my son so we can bush around together.
I think this is the best handling out of the box Little vehicle that I've had. That being said I'm not sure it's going to be a lot of fun bashing with a typhon just because the Typhon can go places this wouldn't be able to. As long as you keep it to sand gravel concrete and really short sparse grass it should be okay but it is still a very small car and has the limitations of being a very small car.
@@DoRC Thanks mate I really appreciate the answer.
is there anything faster?
Turns on what you mean. I'm sure you can make this car go faster or any car go faster with enough power and time. That being said these little cars tend to get pretty squirrely at high speed so I think something like this has a reasonable practical top speed of probably 40.
Will it pull wheelies on 2s?
Yes.
@DoRC We need a video my man. Lol
I think there's a few wheelies in my latest video on it. Can't remember but I believe there were a few in there
Where are the part numbers?
If you're talking about the ESC and motor I discuss what they are and where I got them from at the end of the video.
I would love to see you run this on 2S and 3S with a gyro. I wonder how well that would help keep things under control. For sure going to get one and let my 3 year old drive it in the basement.
I'm sure it would make a big difference. It's not that crazy uncontrollable even on 3S. It's a handful but it's still doable so I would imagine a gyro would make a big difference.
Just as I would expect from an all plastic Arrma… They are tough as nails… 👍🤘
No clue why it didn’t come factory brushless… pretty dumb on their behalf…
I'm going to get two reasons. First one is to save money and keep the price down and the second one is that they're probably going to come out with an EXB brushless version down the road. If you look at the option parts they have available they all kind of come together to make an EXB version.
Too fast for me sorry on 3s - i prefer the stability and improved handlibility that slower speeds grant me anyway.
I completely agree. I think I mentioned that in the video. 3S is just too much. 2S brushless is perfect.
They should of made it at least 1/16 scale 2s brushless stock
It is a little interesting to me that they didn't go slightly larger. This is smaller than most of the competition in the same range and whereas it's a lot of fun and actually handles very well for the size I think a little bit bigger would have been better.
What's the KV of that motor
3800. The info about it is available at the end of the video.
Were did you get the esc mount
I bought it on Horizon. Unfortunately they took all the upgrades off their site shortly after I ordered it and I honestly don't know how many of those they shipped out but it appears as though you can't currently get it.
They just don’t want to ship stuff unless the profits high 😂 wth going on with horizon , talking to LHS they just don’t care because they’re stuck with the program they’re using
Thanks
@davidrueda1617 You're welcome
It's a little ball of uncontrolled fury on 3s 🤣
Yeah it's fun on 3S but definitely not practical. 2S brushless is the way to go.
Do you know the diameter and length on the Keenso 3800kv motor
Looks like 2838 based on the Amazon listing.
@@DoRC oh ok thank you
@@rc_jamm You're welcome :-)
8s?
That might be a little bit of overkill :-)
The only downside with this is the plastic diff gears (over time). Honestly it's only contender at this size and price point is the HBX 18559a which does have all metal gears and comes brushless. But Arrma likely wins due to part availability and how easy it is to swap...well everything.
Well fortunately they're going to have upgraded diffs available. I actually was able to pre-order a set of them when they were on the horizon web page. They have since been taken down but the description said they were going to be metal and sealed so that should be a sweet upgrade.
As far as the plastic differentials are concerned I'm sure they will not last forever at 3S but I think on 2S with a modest system they should be fine.
It wont sell well. People will still get the chineses ones most of the time. A 1/18 scale rc is not a serious rc for inside or outside. Way too small for the suspension to work properly. Maybe a 1/16 with bigger tires would have somewhat worked but 1/18 doesnt do it for me. The only small scale rc i see having its place is mini cralers because of the mini tracks you can make and run on
@@EXTREMERC416 I'd have to disagree with you. I've been running these small scale trucks for many years now and I run them just as much if not more than my bigger trucks. These are great for just throwing in your vehicle and taking literally anywhere. Because It looks like a little toy no one will give you a second glance no matter where you are.
You might be surprised about how well they work too This one's very well tuned and the suspension works just fine :-)
I never had any issues with arrma plastic diffs until you use a LWB and 4s or terrible driving on 4s I guess , possibly the quality has gone down a notch and that’s why , my granite had 100s of packs till finally broke gear and that’s wear metal would’ve been done also , but the brcc I went through a couple using a normal amount . The brcc was after horizon so not sure , that truck broke far more overall , rcs funny like that , can have different experiences
@@RcPlayer-tt2vw the rear plastic diffs strip quick. The fix i found was the hot racing yokes on 4s. Made it bulletproof
It looks nice, but any MJX would eat it for breakfast 🙂
Depends on what your goals are. The MJX cars are cool but build quality on this is higher and both upgrades and spare parts are probably going to be easier to get. This also handles out of the box better than any other small vehicle that I've had short of maybe the 14mt but that's a much larger vehicle.
