If the controller overheats, I think there is a thing you have to do to reset it. I believe is holding the brakes and turn on the controller.

"Temperature monitor:
The temperature monitor switches off the motor. You can reset the unit using the "autoarm" function (throttle stick to stop for about 2 sec.) If the motor windings are shortcircuited the temperature monitor reacts too slowly to prevent damage. Switch the motor off immediately to avoid permanent damage to the speed controller."

That happened to my 32.40 and I did the autoarm function and it is working good now.
