Hi! I have a phantom 3 Advanced with two problems ( Only sometimes, 2 or 4 times per flight and that's bad) - First problem: It doesn't fly straight, twisted to the left ( Not always). - Second problem: The gimbal horizon is not straight. ( I think this is caused by the first problem since it only occurs when the phantom doesn't fly straight) I experience this from the firmware 1.3.2, and I have never damaged my phantom or crashed. I now use, firmware 1.5.30 y Rc 1.5.70 y app 2.4.2 y uso iPad mini 4. I have made calibrations IMU (cold), gimbal, compass, stick Rc many times and solves nothing.) That's horrible and very sad Thank you!
