So I have been having problems with my gimbal roll and gps/imu since the firmware update. I did a proper cold IMU calibration, and compass calibration. As it is sitting on the table right in front of me it said it had a horizontal speed of .2 mph and the distance was increasing slowly. I recalibrated my IMU again, and while now it says there is no horizontal speed, The distance still kept increasing by .1-.2 every second, with pauses. After about a minute it was around 14 feet I think. I'm scared to fly it, because I think thats a sign something is messed up. What could it possibly be? Could a small crash have knocked something around in my compass or IMU? Could I check that myself? Is it likely the firmware? Should I try flying it and record it to see what happens?
