I was going to fly a photo waypoint mission yesterday on Litchi, but when I took off, the bird started to drift a lot more than I'm used to in P-GPS, both sideways and up/down. I decided against flying since most of the mission is above water (it's actually to show the owner of a small island close to my cabin how much I have cut of the top of the trees to make my view better). Anyway, today I drove to a big, open area and tested a litle bit. It still drifted a lot in P-GPS, and it still had a lot of drift up and down. Flying fast back and forth made it sink lower and lower for each turn, much more than I've seen before on warm-up flights. I tried to replace two of the propellers (I have only replaced two before, on maybe 50 missions) to see if that could be the problem. Then, when I was going to start up again it just didn't run the propellers when I moved the joysticks down and out. Litchi didn't say anything was wrong, and after a few minutes of testing (power cycling both the drone, the remote and the Acer 8" tablet I use to fly with) I finally tried DJI Go. And there I saw the message about "IMU is initializing" and I had to wait until it had finished. Of course it never dit. After ten minutes or so I gave up and drove home. I'm guessing that it will work again next time I try it, if not I'll just leave it out for an hour in the evening. Since it's still early spring that means about the same temperature as the frides I read about people using for this IMU thing.
But I'm wondering if the two problems can be related. Is that possible?
