Craig disagree with your theory only cus even with faster motors the slipper still performs great for me ..
Don't know why you can't drive the truck with the slipper .
Maybe you just did not adjust or had glaze pads ?
Maybe overheating everything with mass power ?
The motor I use is slower than most , but my lap times are not ....
I don't need more HP believe me .....
My temps are always under 130, ESC comes in even cooler than the motor....
I know how hot things can get with some of the motors available and have avoided them for efficiency instead...
