Just did a flight in Northern California and took note of a few issues:
1) When more than two buttons/controllers are assigned to one command you can't see it in the controller setup menu. Only when you delete one of the assigned buttons the other assigned button shows.
2) There is no warning if you assign a controller button or keyboard command that is already in use.
I found out about the above issues when I had assigned two joystick buttons for elevator trim. To my surprise the flaps would go up and down each time I tried to trim the elevators. It was almost impossible to find out what cause it...
3) Elevator trim moves too much for each keyboard/joystick press. It needs to move less for each button press to be precise.
4) Lots of autogen trees in fields and towns in Sacramento Valley (Observed doing a flight to Yuba City).
