Exactly. Helicopters and jet planes are a lot easier to control with analog sticks than with a mouse. Besides, the option is already in ARMA 3, so apparently they chose to add it. Now my motto is: if you do something, you gotta do it right, therefore this ticket.

This might be related to <a href="http://feedback.arma3.com/view.php?id=10352">10352</a> , however that issue has already been resolved and fixed (maybe it isn't?) in 0.74.108.135.

You can set cyclic forward (helicopter controls) to MOUSE UP and cyclic backward to MOUSE DOWN. (You will have to drag these to the command list, see here: <a href="http://www.youtube.com/watch?v=QZWPvkkJyqw#t=0m48s"> </a> ). There you have it, inverted Y-axis for flight.
