Hi i have a Peak Racing Hellfire 27t motor and every time i use my 3600 nimh battery pack the motor gets really hot after a few minutes of run time, could this be cause from wrong gearing? Any advice will be very helpfull.

Agree to trying lower gearing. But what kind of shape is the motor in? The comm where the brushes ride, is it a nice shiny copper color or is it kinda black looking? Might be time for a comm cut and new brushes.

Just had a look at the motor the comm is shiny

Probably gearing then. What vehicle, (the Yokomo?) and what do you have it geared at?
