I normally try to fly every Saturday. I normally fly out 8 batteries and sometimes I recharge and fly more but usually not less. For some reason unknown to me my Mavic2Pro has started wanting an IMU calibration every time I fly it. I ignore it for the first flight, sometimes 2 and usually it doesn't come back that day. Then once back home I will recalibrate it and it says everything is fine until the next time I fly it. Then we start all over again. Any idea why it keeps needing calibrated. No crashes, no hard landings, no loaning it to friends.
