Having a little trouble, I'm using a sphere comp speedo, and a lrp x-11 13.5 turn motor. Once I set up the speed control, sometimes it spins the motor, and sometimes, the motor just makes a faint whining noise and won't run. If you give the spur a little bump, it works fine. When it doesn't go on it's own, and you hold throttle, the mode lights alternate blinking red and yellow. Does anyone have any ideas?

I have tried two other motors and sensor wires, same result with all.
