I have a hb 2835 brushless motor and a 450 clone. I had a motor problem (I grinded shaft to much to adj. teeth). So i Bought the 2835 brand new. All 3 wires coming off motor were all black. And needed me to put ends on wires. I read somewhere that it don't matter which wire goes to which. But when I plug it in and give it throttle the motor just shakes. The shaft won't spin. On the motor currently I have it setup with heat shrink colors, 2 outside wires black and red, and middle wire blue. I tried swapping the two outside wires and had same result. Any ideas?
