All I could wish for is redcat to come out with stronger dog bones and drive cups. I have bent and dmg a few dog bones. And I am noticing the drive cups for the drive shaft mostly the rear drive shaft is getting grooves worn into it. The drive cups for the axel don’t seem to be doing that. I am assuming the rear drive shaft takes most of the torque from the engine which is decreased through the gears bye the time it gets to the wheels.
