I'm installing an ESC and brushless motor in my car. I got the ESC + motor used so I was trying to test them.

What I'm seeing now is that the motor will start and run if the shaft is at certain angles, and it won't start if it's at others.

The shaft appears to have 6 difference positions it can sit in in one rotation. If the motor is in 2/6 of the positions, it won't run when I tap the trigger. If it's in the other 4/6 it will run.

The ESC is a Novak Kinetic 2S. I did the Hall effect sensor test and the lights seem to change correctly as I rotate the shaft.

The motor is an LRP X20 13.5T brushless.

Does this sound familiar to anyone? Any ideas? Or should I just resolder all my connections?

Thanks,
Ben
