yep over and under gearing can cause heat probs... what gear are you running?? speedo settings etc...

im only running a basic set up .....
12-1 brushed motor and a Podium 8t speedo
the speedo set up is set for middle rising time ...
im running a 19 pinion on a 87 spur ...tried it with a 21 pinion ...but dont seem to matter ...always gets hot
