You definitely better upgraide that truck! I'm recycling drive train parts pretty frequently with the CV-R in my MT1. All stock drive train. I've bent about 3 drive shafts and destroyed a rear diff. Also spun a hex in a wheel and the rear axle stub slots are started to open up from the dog bones tweaking them. Luckily I have a big stash of MT replacement parts. I'll be upgrading to the 18ss kit here soon and just selling off the hpi 18ss motor.
