motor hot battery warm

Hey guys, I just took out my backslash converion, within 5 minutes the motor was really hot, I have it on a zippy 3-s 5000mah mamba max and vxl motor geared 15-90 with 1/8 size buggy wheels.

the motor was really hot. I am guessing 180-200 or so within 5 minutes. the battery was warm. not hot by any means just warm and the speed controlles was also just warm. i though having it geared this low would be safe to start testing and not get to hot, where is the heat being generated from? undergeared??


also on the mamba max, does it matter how i connect the three wires to the motor as long as it is turning the wheels forward?

and what do I need to set to keep it from slamming in reverse when I am flying and hot the brake.
