BG184854924 Unless you change the pinion gear which requires some modification of the bottom motor mesh screw slot. I carefully drilled away some of the aluminum and now I have a 17T pinion in one Cheetah and a 19T pinion in another. 15T is the stock pinion. I'll be hitting 70+mph on 4s now.

BG184854924 The 120A esc that comes with this truck is rated for 4s. Look up the hobbywing SC8 specs. it says 2-4s lipo on the side of the esc itself! I've been running it 4s and it is sweet!. it's difficult to get it past half throttle 😂

BG184854924 Yes it can, I changed the deans connector to xt90. Just incase it were to melt and short out on 4s. It's unlikely, but 4s is pushing a deans 2pin to the limit.

BG184854924 the servo works great in this truck
