Soo I have recently had a problem relating a qav250 clone build I did a couple months ago. When I plug in the battery and hit the throttle, all four motors spin normally. Every 30 seconds or so flying it will twitch to the front right motor although it is not enough to bring it down. It will also tend to lean to that side as soon as a hover is disabled. When I put a yaw right input, the front right motor will almost completely cut out but not fully causing the drone to crash. I have ruled out the battery option as I used a brand new battery to check, I have tried reprogramming it with openpilot and I have checked all connections to the power distribution board as well as from the esc to motor. I would love to know what is going on if anyone has an idea… Thanks!
