What should I do when Roll axis has a drift during the flight?
You should refer to CANLINK for this issue. If you already installed Canlink but it still drifts, let’s take a look at your gimbal’s IMU. Firstly, do Gyro calibration, then use the red button to turn ON the motors without remote controller (remote receiver disconnected). If the roll level is off in this case, you should do Accelerometer calibration again, make sure the Tilt and Roll axes are in perfect level during calibration. In general, this solution will solve your problem and you can come to do CANLINK setting again. Otherwise, please call us via our skype (gremsy.support) , we will work with you for advanced support.
