Hi,
Yesterday I did a couple of flights with my Inspire, testing it out a little bit. The first few flights went well, and the Inspire behaved as expected. I always calibrate the compass before every flight.
But then on one flight, the Inspire started drifting north. I tried to get it back but I had to struggle with it a bit to get it home. Yeah you can see the result here:
After I got it on the ground I checked the IMU, which all of a sudden needed calibration. I turned off the machine for 5 minutes, turned it on again, and then it said that the IMU did not need calibration. I calibrated it anyway of course. After the IMU calibration I calibrated my compass and took another test flight with the machine and it performed just as it should again.
Scary!
