Hi,
Tried to search a solution for this issue, but couldn't find it. If I assign pitch trim to one of the axes of my controller, altitude hold stops working. This is very close to another issue I had. Controlling pitch trim with axis is convenient, but often it is hard to find the right setting, always overshoot. Then, I tried to assign pitch trim up and down functions to two more buttons on the controller. So, I wanted to change trim with axis and then fine-tune it with buttons. But it didn't work. When buttons are pressed, trim is changed, but then is reset back to the original value, which is read from the axis. I solved this issue simply by reducing sensitivity of the axis.
I think the problem, I have now is very related. Autopilot tries to increase or decrease pitch trim (same effect as buttons), but the control axis set it back. If I disable pitch trim axis in flight, the plane starts to hold altitude. When reassign it again, it goes crazy again. It would be good if there was a function to block pitch trim axis when Altitude hold is selected - the same as throttle and X axes are disabled.
Any solution??
Cheers,
