My phantom 3 is turning left slowly all the time. During straight flight and during hover.  Compass callibration doesnt help and IMU also . Does any one has a solution? Thanks

Can you retry a IMU calibration on a perfectly flat surface and the compass calibration outside free from any interference.
Then try a RC calibration.
