Something must be wrong with your motors...

I just ran one of our Chiaphua motors under no load for 10 minutes at 12.5 Volts.

The motor was luke warm.

Our motor was only drawing between 1-2 Amps. That works out to under 25 Watts of electrical power. At the size these motors are, I would not expect the motors to get much hotter than they got in the 10 minutes.

I think something must be wrong with your motors OR you had built up a lot of heat in your earlier test and it took that long for the heat to conduct through the case.

In any case, I don't think teams should panic about overheating Chiaphua's just yet.
