It's probably because its a feigao motor. Has this been the problem throughout the life of the motor? I've noticed that feigao motors get worse the more you run them. I could be the rotor demagnetizing. I recommend you get a neu motor, and your problems will be solved. The novak motors solved my feigao problems. The hv4.5 geared 10/46 im my 8ght btw is slightly faster with less torque than my 8xl was geared 20/51 in my mbx r2. The 8xl seems to have more torque the higher I geared it, but no matter how i geared it, it still heated up the same amount.
