Default Help! Motor twitches/stutters when servos move
Hello, I just came into an issue with an Xnova motor and Castle Edge ESC. Once everything boots up and motor arms, everytime I move the collective sticks and servos move, the motor would twitch and move the head a bit. Scary! This happens with the motor switch off and throttle hold on. It is like if moving the servos is introducing noise into the ESC signal line. All electronics are connected to a Vbar Neo with Hercules BEC at 8.2V and Ultraguard. If anyone has any idea of why this is happening, I would appreciate any responses.

Thanks.

Case closed. It was the Vbar Neo acting up. Back emf from servos sending junk through the ESC line making the motor spin. Just FYI for those that might run into this issue one day. Something to look for.
