Steve, try to do this way, worked for me making my gimbal better. Take a flat small square surface (wood or plastic are good), lay the table somewhere and level it paying attention to be leveled horizontally, vertically and diagonally. Then put the phantom in the fridge, wait 30 minutes and bring it outside on the level table you prepared before. Switch it on and perform immediately an imu calibration. When imu finished make signs with a pen where the phantoms legs are (on the corner is ok). Take the phantom and perform a compass calibration (thats why i advise to do it outside, houses are full of interferences). After done compass calibration put back the phantom on the table in the exact position where it was when performed imu calibration. Switch it on and check the mod value, it should be 1500. If it is, with the bird always on the table in the same position, perform gimbal autocalibration. Before to perform gimbal autocalibration be sure that your gimbal offset in dji go is set to zero.
