stock everything except front and rear diffs are the nitride ones, got a inovative chassis. all stock otherwise...
the motor was pretty hot after running it geared the way it is...will undergearing cause heat issues like overgearing would? I'll use the calculator and see what that says.
High motor temps would be under gearing (did you record the temps), high esc temps would be over gearing and some sort binding or strain through the drive train...
lets see all the numbers when you're done with calculator...
