A hot motor usually means it is undergeared. If it was overgeared, it makes no sense that the ESC wasn't hot as well.

Also, running the motor to those temperatures might have reduced the magnetic capability of the magnets (intense heat does that), so you might be dumping more power into the motor than you would need with a good motor. Not saying the motor is for sure bad, just a possibility.

Brian thanks for the quick response and insight. I must say the reason for my gear ratio was to try to over come the cogging issue. I figured larger pinions (which if i read your response correctly, would help reduce heat from the motor) would make it cog worse since it required more torque to turn the driveline

Well, you are right. If geared too high, the motor doesn't turn enough from a stop so the ESC can get feedback pulses from the motor. However, you have it geared low enough that it ends up spinning too fast at high speed. IMO, it sounds like the motor doesn't have the start torque it needs (and cogs) but then spins too fast once it gets going. You could have weakened the magnet with the heat which would also affect both cogging and heat.
