150 degrees Fahrenheit is too hot? That is about 65C Celsius.Unfortunately it's getting about 150 degrees give or take using a temp gun and Horizon says that's too hot. That is a velocity stack/rock guard
Look at what Hobbywing writes about there 3665 motor:

I would not be worried about 65 degrees C, if it would be 85-90 degrees C, is a different story, but don't battle 65C/150F.
