Hello, my plane is having this issue that calculated attitude begins to drift from real attitude, so if flying in an stabilized mode it can crash the plane.
My flight controller is a Matek F405 Wing
Video of the crash
I didn’t have time to switch to manual mode, had to switch but with the sticks all deflected I just crashed.
In this log you can see in the moment of the crash I am commanding the control system a 20 degree pitch, and the plane thinks it is already in that position so it can’t pull up more.
This has been a problem in my flights because it appears randomly, other times I had more luck and did not crash. I also have noticed that sometimes attitude will drift when sitting on the ground. I also think that this might have something to do with the EKF because when there is no gps I have never seen this behaviour appear but might be also due to vibrations or something I don’t know.
Thanks for sharing your thoughts any advice is apprediated .
