I am new to this. Had my P3A for about 2 months. I did a IMU calibration after fw update and now when I yaw while in a hover there is a slight drift, when I first got it, it would yaw on a dime. I have now done another IMU calibration ( using a sheet of glass over motor and level), but same results. I have searched the forums for solutions and all the threads I came up with were for the p2. In those threads they suggest doing a calibration with it shimmed to one side or the other, making it in unlevel for calibration. I did not find any threads on the subject about the P3. So I'm wondering if I should try this unlevel imu thing or not ? Any advice would be appreciated. Thanks !!
