I have not flown for about 5 months and the bird is on FW 1.4.10, the RC on FW 1.3.20 and the GO app on android is on 2.3.0. Never had an issue before with this combo and planning to go calibrate my compass as it has de-calibrated (value shows about 2000 thats not good) but not planning to calibrate IMU. Is this ok to fly once i re-calibrate the compas only? By the way what are the best IMU values? I know for the compass the value should be around 1500. Should i upgrade the FW of the bird and the RC? If yes Can i jump from the FWs i am on to the latest once via the auto update on the DJI go app? App is asking me to upgrade.
