Yes, plenty of power for flips now. I have the HRB 2200mah Graphene 2S pack I mainly use and also the HRB 2200mah Lipo 3S pack. Yoowoo and some other brands make the same spec battery, may well come from the same factory. I tested them against a CNHL battery and noticed no difference between them.

2S www.amazon.com/gp/product/B0C65BZH2W

3S www.amazon.com/gp/product/B0C7Z1XGN9

I haven't found the HRB in 3S and Graphene, but I have heard that these work really well and are made by the same company www.amazon.com/Graphene-Parkzone-Airplane-Quadcopter-Helicopter/dp/B08QDFGKRW

Arrma is out currently, but a lot of local shops have them or if you hunt by part number you can usually find some online in stock still. ARA311193 This place has them as of this post www.gallimods.com/shop/c/p/118-HD-Differential-30T-08Mod-3000cSt-Oil-2pcs--GROM-x79192113.htm

Thanks! 1) The ESC mounting 'feet' are from the Hot Racing kit hot-racing.com/?partnumber=GRM2401;c=1909 2a) It is the Arrma mount set www.arrma-rc.com/en/product/motor-mount-set-8pcs/ARA320744.html 2b) Pinions are various tooth counts from LC Racing, I bought several from www.hobby-addicts.com/products/lc-racing-l6032-motor-pinion-gear-set-17t-18t-19t-for-3-175mm-shaft?_pos=1&_sid=d8fc1550b&_ss=r 3) Motor screws I have a large spares box I keep. I think the new motor needs M3 screws, if you don't have any handy you can get a starter kit of spare screws from Amazon (or Jenny's for the larger scale RC's)

Thank you VERY much for what you’re doing for our RC community and for such a fast reply! Very helpful! Another question… do you know what motor temps you were getting on 2s?

@@ringo101079 yeah I don't get the gatekeeping some do, it makes no sense. I haven't used my temp gun so I don't have an exact to number give you but it doesn't get warm/hot unless I'm pushing it on 3s. Even then it's still within the limits. Off road may run a little warmer, I will be doing some more videos soon hopefully

Thank you!! What length M3’s did you use??

@@ringo101079 either 8mm or 10mm, best to check depth in the motor to make sure they don't go too deep

I go over it in more details in my other videos but XERun 2848 4600kv + 10BL60 ESC . Perfect bashing 2S and speedrun 3S setup, and will outrun a lot of other 3S setups on just 2S.

Thanks for the tip! That is kind of the same conclusion I was coming to. I'd like to stick with stock tires for now but going to play with diff and suspension to see what can be improved

@@Killer_of_RCs thanks much 👍

@@Killer_of_RCsah, you got the 4600k? Which esc? I think I might go your route.

@@AnthonyBencomo yes, 4600kv. 10BL60 ESC

I have seen a few fit (or working on fitting) the Castle Micro X2 into these. That can also do 4S! I can't even get full throttle on 3S with this setup though so maybe with a tamer motor. With a few upgrades these are really great.

@@Killer_of_RCs Man, I am so out of the loop in rc, I thought the Tekin mini rage was the top dawg. I have 3 of thes esc, apparently they are rare, I had a few castle setups in mini t pros back in 2004. Castle makes great stuff.

Yeah this setup is really meant for 2S, 3S is just for speedruns because it is too much. I would get a nice 2838 or 2845 size motor, 3500-4000kv. Should get you 40-45mph on the stock pinion on 3S. Still recommend the 10BL60 over the 16BL30. Definitely don't try the no-name ESC combos from Amazon. They are all junk.

@@Killer_of_RCs Thanks man, that’s great info. I’m not lookin for crazy foam tire speed runs, just more speed and fun….and some back flips😜😝🤪

This is the new XERun 4600kv sensored motor. With the adjusted timing it behaves more like a ~5600kv motor up top. A normal unsensored 4600kv motor with the same pinion would probably be around ~43mph on 2S

Yes, I made some radio adjustments and it has helped. Working on some other fixes as well, should be back and hopefully hitting 70+ soon!

Out of the box the only thing it needs to make it reliable would be the diffs. Hardly $300. I don't know any RC that you can literally triple the power and not expect to break things. Once you want to go that fast, of course you need more upgrades to keep it reliable, and that is going to cost money. Show me on the doll where HH hurt you

@@Killer_of_RCs yeah right a crappy brushed system suitable for a 12 year old kid. You may be on that level. I am not. My Grom has sat on the shelf for months because HH hobby has everything on backorder. How about HH putting out a truck that already has all the upgrades. Oh wait Then you wouldn't be able to continue to line there pockets with money. HH hobby sucks . There costumer service is horrible and there website is horrible as well. Diffs on the Grom junk driveshafts junk shocks junk tires junk Bell crank junk. Brushed system junk. Do the math after all those upgrade replacements around 300$ .

As you write that, diffs are in stock now (again) and I've had no problem getting 4 sets. Just have to pay attention. They obviously either underestimated demand or overestimated the stock diff strength. Maybe they'll learn from it or maybe they won't. Either way I'll be enjoying my Groms and other Arrmas.

How about the shocks and the upgraded axles ? Stick up for HH all you want. They suck to me.

​@@Killer_of_RCswell said.

Should, but that is a pretty high kv motor. I know some people have used them in the regular granite. Not sure how stout the combo ESC is in that

Yea its only 20 watts continuous 40 peak

@@davidpunches237 yeah I don't think that will cut it then. Maybe if they offer something closer to 3500kv. I think the brushed ESC is 25a

@@Killer_of_RCs thank you in your video what gyro did you have.

​@@benwilson2420 it's an RF6G radiolink receiver, has it built in. You can also get a standalone one that goes between the servo and receiver but that is more wiring and space needed

Not needed but definitely helps, especially with the small scale stuff like the Grom. I'm really close to 70, will be posting another video when I crack it!

@@Killer_of_RCs I am fairly new to rc, and the grom is my first small car. I didn't see or hear you say where the gyro is and what kind you used? is it seperate from the rest or part of the esc? I like the gyro on speed runs.

@@MrGonzoify so normally the gyro is built into your receiver, but you can get them separately. However with the space constraints, it makes sense to get it all in one unit. An example would be a Spektrum sr6100a paired with a dx3/dx5c/dx6c radio. Or in my Typhon I am using a radiolink rf6g paired with the RC6GS radio.

@@Killer_of_RCs Thanks for taking the time to answer. I did some research on the web, and ended up ordering a radiolink combo with the built in gyro. I also picked up a brushless set up that should fit in the space. Thanks again for all the help, cheers.

Would have to go in front of the motor/heatsink on that center stack. It is possible but then it messes with battery clearance and battery install/removal as it is overhanging or blocking (for tall batteries) the tray.

That may be an option, but it's not a standard body post since it is a clipless body. If you had a plastic rod you could probably just make it work with a dremel or file and then just space up the rear with some washers.

Yes I had to on my 6S Typhon as well! Same idea just different implementation
