Doing an orbit mode you need to hold both sticks in one position for as long as 30 seconds. Is there any way to hold that sticks using some ... I do not know... some stick between stick and controller?
Genius!
If you hold the controls in the same spot for too long, it will execute RTH, at least in my case, I fly the FC40 & P1.
Or you could cut off the top of a cereal box and put a hole in the cardboard.
Slip the hole over the control stick and hold it down (it might take 2 fingers and a thumb to hold it in position). Hold the cardboard firmly to the controller to maintain the desired control input.
