Unfortunately the chassis is 3mm Plate, 7075-T6 Aluminum stamped not machined 👍 another side note the warranty LSD diffs are failing under 6s rather quickly and the metal wheel hexes are stripping the wheel hexes as the metal thickness doesn't match up to the wheels installed. Aside from that the EXB looks nice
Appreciate that my man that why I subscribe to your channel honest content got me thinking about the mojave ⚙️🔋
Brett is definitely one of my idols, gets to mod and play with rcs for a living 😂
I also do that and belive you dont want it. If you do it on daily basis you get bored of it. Where i live we have a saying if you have a hobby make it into a job.... and then find a new hobby.
@@Ev0ltion true that
Love mine and it was a first batch one that stripped the diff first run on 6S. Just put new spider gears and LSD plates in the rear I was back in business.
CONGRATS ON 100K!
Excellent breakdown on the EXB models by Arrma, they have done so many upgrades to it. Love the details on the electronics you picked. SHE IS A BEAST!
Everyone is coming here for the Arrma review, but I think more people are gonna end up buying those connectors
I don’t trust it.
Agh, I was looking at the Kraton 6s, now I want this! This stuff is addicting .
I have the V5 Kraton 6S and dear God is it a beast and its beefed up more than I realized!!!
How hard do you bash? Full send airs get the EXB for sure
@@based_will I don't bash very hard. Haven't gotten much playtime this last year im still learning how to drive the ones i have and do flps. But because im still in the learning stages I do worry about breakages and I have added 2 upgrades to my Kraton
@@newamericatowguy3633 which upgrades?
@@kristinewilson5353 RADICALRCUK 7075 Aluminum bash bar that bolts straight to the chassis, RPM front bumper, and TEKJO diff case gaskets, and my tires are vented just as RICHDUPERBASH has suggested.
Awesome job as always guys 👍
Idk what it is but I could listen to Brett talk for hours 🤳👂
Where have those solderless connectors been all my life?!? And driving into that solid metal box in the grass for the win, LOL!
Darn truck was supposed to jump that!
-Brett
So glad you guy's posted this. I have the same setup in my exb and have been bashing on it for almost a year now with no issues.
Are you still using the 12T pinion? If not, what did you change it to?
-Brett
@@AMain_Hobbies no im using a 19t on mine. Seems to keep the temps good.
@@joshherrman3201 Great, thanks Josh.
-Brett
@@AMain_Hobbies i hear 21t is a good combination to i have not tried it out yet tho. You guys rock Brett!
Some of the best driving I’ve ever seen right there 😳
Nice Combo and the Arrma jumping in the Gras like a Rabbit :)
Ok, I didn't know those battery connectors exist, it peaked my interest. High amp, solder less? Say less.
Not for $60usd!
I'll stick with ec5. I only use 3s batteries anyways so I'm not worried about them.
Even at $30 I'd still cringe, but at that price I would get them. Not no 60 bucks to outfit 1 car and 2 batteries. No. thank. you.
The diffs are undersized!
And def need to be shimmed!
I saw a few of these at my local hobby shop and it's so funny to me how absolutely massive they are. I wish I had a place to run something like this! By the way those sick whips you were pulling on those jumps were very satisfying and impressive.
Cant believe that the hobby manufacturers aren't supplying these machines with decent belted tires. Yes I know that some 8 year old grown-ups love the ballooning tires effect, but they're inefficient and unbalance the vehicle! I bought some Belted Proline Trenchers for my Team Associated MT10 and it's so much more controllable now!
I have kraton 6s rtr then bought some exb parts.. I'm not yet content so I might go for M2C parts.. I'm glad I bought kraton as my first hobby grade
hey, love your reviews. I am just completing my build. Went with HW 1650 can. I just removed temporaily the side guard, to install motor, then replace after. I did have to trim esc mount plate as the Max6 esc is a little too big.
I can see that ESC plate needing trimming; we almost had to also. Have fun with your truck! It will be an absolute beast!
-Brett
8S Outdrive Snapper!.. Powered up to the EXTREME! *I've seen that break happening on box stock Kraton V5 also... so the that part might have a new metal defect or weakness. Something to keep an eye on. Great Video.. congrats on 100K!
Good to know Netcruzer! Wasn't sure if that was the 8S or not. And thanks on that 100K!
-Brett
That Whip was the trick of the vid!
I am also running this setup ( Spektrum 1250KV and 160A ESC combo ) - 20t Pinion on 6s yields near the same performance as a stock Kraton 2050+150A(15t) but has more torque.
Temps are low-low-low which is a huge plus for Texas summer !
I normally run everything on as much as it will take - and even I hesitate to run this on 8s full time as it is nearly unmanageable and my wallet will hate me.
Great review - you are amazingly under geared and I suspect you could twist rebar with that much toque going through the drivetrain ! :)
Lower KV on 8s is muh more efficient. More power, longer run times and cooler temps. 1250kv on 6s is very inefficient with such a big truck. I run mine with a 520kv and 10s 4500mah, I get 45 minutes of bashing and temps never exceed 118f.
My only complaint with this truck is the diff's. They need to be shimmed right out of the box. if you don't you might end up with some shredded gears. Other than that I believe this is the best 6s version of the Kraton yet!
My Kraton 6s v5 will be delivered tomorrow. :)
Nice
Mine too!
@@zerotobeesixty7050 you’ll love it
@@zerotobeesixty7050 check differentials

Love the plugs I've gotta get some for my planes No soldering is nice and neat very simple The EXB is definitely one of my all time favorite RCs 🔥👍
I run a 22t with no issue on 6s.
8s is just uncontrollable.
That sound is from being way under geared.
Yeah I'd like to see that truck with some taller gears. It just looked like it had SO much torque and it was lacking top end. I wonder if that's why the out-drive broke?
@@Dartheomus definitely. IDK what they were thinking with that gearing. I wouldn't gear a 2500kv motor that low.
Same setup but 20t - are you running a heatsink and fan combo ? Any issue with temps at 22t ? ( I'm at 20t and tempted to give it a shot )
@@veryconfusing No temp issue in the winter with it below 50deg. Summer time I back it down to 18t.
@@tommys.9606 Thanks ! - I'll give 22 a go now that it's freezing out ! ;)
I was literally think about this same build a few hours ago haha 😂 I need it !
I personally am not sold on the arrmas but HH has amazing customer support!
Have had bad luck with the one we bought. Amain has been awesome with support on it.
Love the kraton 💓
Woah that thing's got some power!
I bought this truck when it came out, the rear differential failed on the 2nd run. Since the truck came out I am still waiting for a replacement rear differential. I also can’t buy it locally because it’s not in stock. Absolute terrible part support and waste of money. Thanks for the vid, makes me wish I could take mine out.
My esc went out and they had one on my doorstep in 2 days.
Thanks for the video. Nice honest review.
Besides the diff issues they need to fix those huge tires with such a small hex that moves like crazy. Even my V5 seems loose when the wheels are completely tight. For $600 plus a battery....come on Arrma.
It's a beast, Just make it what you want. I'll stick with the RTR's. Much easier for my old hands.
Like the solderless connectors
I LOVE MINE. ITS A FREAKING BEAST THAT ALMOST DOESN'T NEED ANY UPGRADES OUT THE BOX!
@@williamperri3437 there's no need to do that. The new batch of Exbs have fixed diffs already. They are even well shimmed and 4 extra shim rings come with the kit.
It’s crazy. Those diffs broke before the jump, you can hear when it breaks going up that grass hill
You're right. I went back and watched/listened at 7:55 , it for sure broke on the jump, before air.
@@indyjones3287 there was probably a small hole on the ramp he was going up and going full throttle the diff went out
I have the Spektrum 2050kv system in mine, on 6s, and it's a handful. I cant imagine 8s power.
I’ve just put in the same in my exb but not ran it yet, what size pinion you using
I did the same with mine. 12 tooth Damien comes with it 👍
@@jordansrc8483 heard 12t is under geared?
@@Scoodee17 it may be slightly for the 8s system but I haven’t had any issues with the 2050kv system and the 12 tooth pinion (yet) lol 😂 👍
@@Scoodee17 Mine is stock pinion. I bought the esc programmer box, and set it to start level 3. Seems to have tamed it a little.
Good video. Love my EXB, it’s a BEAST!!!
I think I’ll buy this EXB, or a used Kraton chassis and rebuild. I plan to do a bunch of m2c upgrades so a used chassis makes the most sense possibly.
Wow! I need to looks into those solderless plugs. Sounds super convenient......My EXB must have been a first batch truck cause I stripped the rear diff on the first run. Opened it up and found that Arrma didn’t put enough shims within the diff. It was a nightmare to get ahold of a new diff. They eventually sent me an lsd to put in the rear....it took nearly 4 months to get it though
4 months! Wow, i'm sorry to hear that. I had no idea people were waiting that long for parts. Hopefully the truck is running at 100% now without issue.
-Brett
@@AMain_Hobbies yeah I do have the new lsd diff for the rear now but I was pretty disappointed in how slow horizon was with getting me a replacement. It’s all fixed up though so it’s all good now!
Please do a review of the Typhon 6s V5!
arrma drunk watches your vids his a big fan of yours arrma tuff
I can't believe the kraton 6s can take 8S power.
It took me a while to drive that thing on 6s
Tomorrow is the first day since two years that I own it to drive it on 6s🤣
This car is ultamite, better than most other 1/8 models out there
i run the 22T on this combo with 6s, works great ;D Awsome video :)) Tanx
Using a sensored setup on a big truck is just the best.....
Alex Chinchilla
Great video I think I'm sold on this model for my 1st purchase of a RC like this, I'm excited to do a build and get into this world!
Thanks for video. More on this exact setup please
gear box looks crazyyyy!!!
Best R/C I have purchased, oh and it came from AMain!
Arrma needs to come out with a line of 1/8th scale trucks that are plastic chassis and the rest of it except for the stuff that needs to be metal like drivetrain shocks etc. with a team of amazing people like arrma they can really create something crazy tough. They just need to accept that metal is never going to be as tough and cheap to replace as plastic when it comes to these smaller models
Love the kraton👍🏼
Exactly what I have in mine sans the connectors I run ic5s and run it on 6s 👍
8s awesome bro I really want one of these
Those solderless connectors, that design has been around for ages ( like, since the '50's) for wire nuts used in homes. Super tough.
Curious about the slot in the chassis that exposes the spur gear. That doesn't exposed that gear to trouble? I could see grass or something getting sucked up in there.
Every once in a while, when the stars align just right, a rock gets stuck and locks up the system. With nitro cars, there is a similar slot for the flywheel and a good rock will stop you in your tracks, but it's pretty rare.
-Brett
the easiest way to make these bomb proof is to tube chassis it . rc4wd just came out with a monster truck 1/8 tube chassis for $150 . i cut the 4link section off so it was flat then welded 8 tabs to it then bolted it to the exb . im gonna just build a tube frame of my own so that the flat cassis can get tossed . if armma did this they would be lightyears ahead of traxxas !
Weird choice for the motor, you guys sell exculusively the MMX8S / 1520 sensored 1650kv brushless motor which the ultimate combo for this specific car!
That thing needs a 16t and it would be perfect. Wheel speed is crucial
It's a Bruuuuute
Can arrma come out with a outcast EXB already
My Dream bro 💯👌 very nice
Good combo " all the best bro
M2c makes way stronger tool steel diff outdrives. I would also put a larger pinion on to give it a little less torque
Congratulations for 100k subs
So, I live in a cold spot, First run on 6s and one or two small jumps on packed surface and front right diff cup snapped. temp above 0° centigrade. Is there a beefier diff cup I can swap for?
Not that i'm aware of. I've heard the cups used on the truck assembly are weaker than the retail packages. Maybe there was a running change perhaps but (some) trucks still have the bad outdrive. Once we changed ours, we had not more issues with any driveshaft/diff parts.
-Brett
Thanks! I just started ordering almost everything from Amain now. fyi
congrats on 100k subs
Very Nice i want one
Strange how Arrma included a small 12t pinion, I’ve seen most people have been using 15t to 20t pinions depending on motor KV & Lipo voltage.
Are you going to try a larger pinion for the fun of it? I think at least a 16t pinion is in order! 😎👍🏻
Can you you do a video on just them connecters
Yes new video!!!!!
100k sub silver play button is cooommmee
🎉
Did Arrma removed some EXB stuff for the current EXB RTR? it has more plastic now looks like.
Brett I had another question for you as you know I am looking into building out a 1/8 EXB myself from all my million other questions I have asked you so far LOL.
How is it you wire up the batteries to the ESC when you end up using 2 packs? Since I know if you are able to run a single pack i.e. 6S, 4S, etc it is easy since you just have the 2 wires from the ESC with the single connector on it.
But if you are running 6S or 8S and have to use multiple packs to how it is you connect the two batteries to the ESC if there is only a single connector there?
I am have not seen a setup in person where I could just look and see how it is done. Only thing I picked up is in those instances there is a loopback adapter you need to use when you only use one battery instead of two. And I cannot get a good enough look when I pause your video to see how it is wired up on your rig here.
Off the ESC is one negative and one positive wire. To have two connectors, we add a jumper wire. So on the ESC, the positive wire will go into connector 1 and this will be the + for this connector. Now take the negative wire and put that into a second connector and that will be - in this 2nd connector. Now add a piece of wire going from connector 1 - to connector 2 + and you're done. Here's a picture of the jumper wire in use: www.amainhobbies.com/arrma-blx185-brushless-6s-esc-ara390211/p-quact2kqgm2xactz
You can see the two wires coming off the ESC and then the extra jumper wire going from connector to connector.
Hope that helps
-Brett
@@AMain_Hobbies Brett thanks for that I do appreciate it and the link. So is it pretty much like wiring it up in series then? So it would essentially be like me using the Traxxas Series harness on my daughters 1/16 E-Revo (www.amainhobbies.com/traxxas-series-battery-wire-harness-nimh-only-tra3063x/p-qeaktawq6zqxactz)?
Careful with those protek lipos. I bought 6 of the same ones. They all puffed in the first 10 runs. protek servos are nice though.
Thanks for the info! Our packs look great so far, but we'll keep an eye on that.
-Brett
I've been running mine in the Xmaxx with a MAX6. They can get warm but don't puff. XT90 connectors.
Take a shot every time he says "EXB".. ok, call the ambulance.
Hey Brett, did you ever work out what the whine was, when i got my exb if you pushed it it made a clicking noise from the diffs, after taking a good look at it, the diffs are in backwards, the curve on the crown wheel and pinion teeth cause the click/ noise, plus flipping them made the motor run correct direction, this may be part of the diff blow out issue. ran it today with the flipped diffs and boy what a combo that 1717 monster x is, even on 6s with a 19 tooth pinion its crazy.
Interesting. I'm surprised they would be in backwards but good on your for finding it out. I think our whine sound was from our motor but I'll have to look into this. Thanks for the info!
-Brett
Those are 4s diffs if I've ever seen them
🤣🤣🤣🤣 fuqrys
My 1717 sounds just like that one.. unlike my 1515 with the same pinion/spur.
it performs same with good 6s combo. think 8s is too much for these diffs imho
Great video guys, but I’m wondering what electronics to use in the 1/5 kraton exb?
Hmm. You have some good options from Castle, Hobbywing and Spektrum Firma gear. All good options.
-Brett
This is a darling. If I won the lottery the misses would lose it with what I would buy
All you had to do to get the motor in was remove the side guard, then put it back on after the motor was in place. No need to cut it.
I put in the hobby wing 1650 and I never even thought of cutting it. I flipped it over and removed the screws, seemed easier than chopping it.
Lots of people are having issues with this truck buyer beware. Even tho i have 0 issueslots of people have differential issues along with under sized wheel hex.
It was a quality control issue with early batches. Its been fixed
@@bingcringing it has not been fixed i have seen a ton of issues and not much has been addressed. It could be user error who knows. I do know qc has been down from everyone because demand is so high so hopefully that changes soon.
Y’all should get an xmaxx
I'm gonna order one for my 50th Birthday question about how long does it take to install the electronics to get her up & running
Great birthday present Jon! Happy early birthday. For the electronics, they install in an hour or so. Setting them up might take another hour. You'll want to calibrate the speed controller to your transmitter, center the server and set the servo endpoints so it doesn't try to throw further than the mechanical steering system in the truck. We have a video on ends point adjustments (EPA) here: ua-cam.com/video/ha84jFODSCg/v-deo.html
UA-cam probably has a video on ESC calibration too, depending on what model ESC you get, but it's pretty easy if not.
-Brett
12T pinion is way undergeared for a 1717? Sounds about right. I am running a 55:34 gear ratio on my EXB with a castle 2028. Also, 1st break on the AMain Honey Badger was the same as on my EXB.
Thanks for the gearing tip. Did you break any more outdrives after replacing it?
-Brett
@@AMain_Hobbies I haven't had any further breaks at the outdrives. Arrma built the EXB to tackle some heavy 6S action, but when people (like us) step it up to some serious power beyond what it was designed to take, parts will break. If you still have outdrives breaking, take a look at upgrading to the M2C hardened steel outdrives. For that matter, check out M2C for replacement parts if you are looking at strategically upgrading parts instead straight replacing them (rear towers, etc.).
good luck affording either of them
This stuff gets expensive . I am happy with a modified Kraton that I keep in top shape otherwise I would run out room for all these rigs.
You need a 23 tooth pinion on 8s
how much is the pinion on 6s
@@tynho8502 I would do 24 t pinion and smaller spur on 6s
for a brute it sure seemed to break quick. bummer dealio !
Seems to be the perfect setup for the RC. If I build one, I'm gonna go with that exact setup. I'd like to know how it's handled more than one run though as I've never had a breakage (aside from a Losi DB Pro) on the first, second, or third run. Once everything loses the factory new fitment between parts is when things start to become compromised and break.
i wanna get one of these to send it to the moon lol my xmaxx can only fly so high
I want to see you take this thing (as is) out on Silver Dollar or your carpet track XD I would also like to see a pro take it out on Silver Dollar.
I had the same issue with the back left dogbone coming out and breaking the outdrive cup. It happened 3 times in a row. I removed the rubber insert and put a small plastic washer on the wheel hub never happened again.
Washer on the inside of the hub? Like to push the bone deeper into the outdrive? I don't understand.
-Brett
@@AMain_Hobbies yes exactly to push the dogbone into the outdrive cup. I tried replacing the dogbone, the arm and still the dog bone kept popping out for no reason and destroying the outdrive cup until I put a small washer to push the dog bone further into the outdrive cup. Diff is shimmed and doesn't not move so it wasn't that either. The camber is exactly the same as the other side too. I have no idea why it only happen to that side like yours did.
... slightly confused... Is this a 6s exb built for 8s?.. it seems too small for the typical 8s kraton
its meant to be 6s
You can run it on 8s who cares
@@bingcringing i mean you can but the diffs and stuff are made for 6s so your just gonna kill it
Brett how you doing? Hope you had a wonderful 4th of July weekend. I had a question what are your thoughts on the stock bulkheads on the Kraton EXB? Do you think that is a part that is worth upgrading or needs to be upgraded?
Thanks Donnie. Hope you had a good 4th too! We've never broken a bulkhead so it hasn't been an issue for us. But if it breaks on you, it may be worth looking into some upgrades. Did you break one? Did you get your truck yet? You must have by now...
-Brett
@@AMain_Hobbies Brett yeah I got the truck. Been sitting in pieces for the past 3 weeks as I try to figure out how to build it and waiting form Amain to send me some of my orders still.
Couple quick questions
1. How do you attach the ESC to the EXB? Is the ESC double sided sticky tape or am I just not seeing how it screws and secures in (I am running the same ESC and Motor you guys choose MM8S and 1717).
2. For the servo what servo horn did you use? The Spektrum one that came with it I Don't think works or I can't figure out how to get it to work. So I need to get a new servo horn.
3. Do you use blue locktite on the screws for the sliding motor mount and motor or do I just use bare screws?
@@DonnieKluck Hey Donnie!
1) Yeah, double sided tape is the ticket. Protek has these two tapes: www.amainhobbies.com/search?s=PROTEK+DOUBLE+SIDED+TAPE
The grey stuff is very flat and not my preference, the other stuff though is like a jelly tape with some movement, so it is shock absorbent in a way. It's the only double sided tape I use for r/c, but it's a pain in the butt to work with sometimes. But rubbing both surfaces with rubbing alcohol, nitro spray or brake cleaner first, and using an xacto knife to raise the backing helps. With this, the tape should never come off.
2) I think we used the servo horn that's included with the 370tbl servo if I remember right.
3) Definitely the two screws on the top that secure the motor mount, but don't loctite the two screws that hold the motor. For whatever reason, you don't loctite motors in, just the other areas where a metal screw threads into a metal piece.
Hope you get those parts soon Donnie!
-Brett
@@AMain_Hobbies Brett thanks for the information appreciate it as always. Really I would have thought that the motor would be loctitte as well so that is so like all against all odds and what not. Weird I would have lost that bet for sure. Yeah I have most the parts I need waiting for a couple others though.
Can you make a video of how you put the servo
You reach 100k
What is the best Truggy in this size? Looking for something that's durable so I don't have to fix something everytime I drive it.
Tekno Eb48
Couldn't you have just removed the side trim to install the motor instead of grinding off the mounting point? 🤔
Yes, you could just remove that piece instead.
-Brett
