All of the above assumes* that the motor has enough power to move the truck at the desired speed and handle the load. For example a vxl motor will not get an emaxx to do 50mph without getting hot. It may produce enough power to do the job, but will be operating past its ability to disapate the heat it it making due to the fact it is ocverlaoded by the weight/gearing. Correctly sizing the motor will allow you to then apply the info listed on cold/hot motors and escs.

Plus battery type and capability are a huge factor in keeping the heat down in a system. If the voltage does not sag the amp draw will be lower for the same output - watts = volts x amps.

So without more knowledge, checking temps does not really give you an insight into why the system is making too much heat.

I will say that I have setup alot of rc cars with brushless, and have never had an issue with heat produced from undergearing... I always geared for 40mph and used what appeared to be a correctly sized motor. I think cheapo 2 pole motors may have more issues than good quality 4 pole motors.
