I am running a dji flame wheel f450 equipped with a 3DR Pixhawk autopilot system. The problem is that no matter how low I set the pid values the copter sill oscillates. I have replaced the board once already and saw the exact same thing happen with the second board. I ran a test of the sensors on the second board to find that all the sensors are working correctly. The esc's are wired correctly, and the motors are spinning the correct way. I need to know if there's a problem with the board or if a bad motor/esc could be to blame.
