read a thread on that and was trying to do something that takes less modification

Would the integrated brushless motor/ESC from the mini-b and mini-t lineup work?

I actually ran that setup before going full psycho Castle system with mine. It’s definitely a huge step up from stock.

what castle system did you use

*some modification required lol

Gonna be honest, it’s totally mental. You can’t use anywhere near full throttle without a violent wheelie at any speed, and packaging this setup in this truck is very tight.

Thats insanity, how does the drivetrain hold up with all that power?

So far it’s been fine. I have the heavy duty diffs on the way. Should be here Wednesday.

 

[Goldendrakester]

Thats suprising, with all that power you would think the diffs would give out in seconds.

I take it really easy on it on takeoff, and I don’t punch it very much. But, my new diffs came in today, so we will see how well they’ll hold up.

Because like everyone else, I just cant leave anything stock Since all my other rigs have Castle ESC's, most likely going with the Mamba X Micro for this little beast. So many different motor options to choose from, but what are y'all's thoughts on the Castle 1/18 motors? 4100KV or 5300KV? Hobbywing Quickrun? 4500KV/6500? I think both motors are solid options, and am guessing the 4000-4500 KV range is about right for these Groms... without going full ludicrous? The above mentioned Firma motor/esc it tempting as well to keep things compact and nice and tidy. Oh, what to do, what to do....

This is a cheap 2845 3200kv from amazon and a 10bl60 ESC. Cheaper combo than the castle. Works pretty well too.

XJeepguy and FredW90, definitely been following your threads, very clean and tidy builds for sure. That is impressive speed Fred, why am I thinking of a mosquito hopped up on coffee and Red Bull??

Its tough to keep the front wheels down or control it at all for that matter. I’m debating aluminum parts just to increase the weight and maybe make it a little more stable.

I have the fluid filled diffs on the way. Haven’t had an issue with the stock diffs yet but I have only been zooming back and forth across the parking lot.
