I would do the MMM 2200 combo on 6s... literally; I have a GTP with RCM mount and Castle 2200 motor and some 6s batts, all I need is another ESC to get it going (could steal one from another rig I suppose). Still need to paint the body too.
Here is what I have so far.Its a freakin monster.I am running 3s with a Neu 1515.5y 4400kv.This car is only 9.5 lbs so it never overheats and its a blast to drive.Really fast and ya gotta run foam tires.The rubber tires arent balanced as well.Get the hardened steel ring gears for the front and rear diffs.Have fun
