anyway it seemed like it was running great for about 20 minutes until we realized the power cutting a bit from a dead stop. after we pulled it in i could tell the motor was smoking hot! check the temp and it was 270 degrees!!!!

i checked if my pinion was to tight on my spur gear and it wasn't. i waited for it to cool down and put a 14t pinion on . it stuttered on starts again and i had my son run it around our very small indoor track 2 laps brought it back in and the temp was already up to 220 degrees.

speed controlled never got hot.

i'll call associated tomorrow to see if they can help me out to as why this is happening. does anyone know what the problem might be? this is definitely not what you want to happen after you install a $260 part in your rc...
