You wouldn't notice anything running the motor off another battery because it's getting a constant DC voltage. Unless the Victor is running at 100%, the voltage will be jumping between 0V and 12V. If your PWM is running alongside the power leads for long enough, it could be slightly coupled with the leads, and will pick up some of those 0V to 12V jumps. Especially because the FPs can draw large currents.

Try running a temporary PWM completely detached from your chassis and away from all other wiring and see if that fixes the problem.

1. Our camera TILT servo motor *always* gets the jitters when we have the RC disabled (with the dongle).

2. It *almost always* get the jitters while we are downloading code to the RC.

It has always behaved this way, even before it was mounted on the robot.

Anyone else seen this behavior?
