Yeah, currently using a Xbox 360 wireless controller . Everything works great . Had to adjust dead zones ( +18 ) and also reduced sensitivity ( - 30 on both sticks ) . Takes a bit of trial and error to find the sweet spot .
The constant pitching up and down sounds like the sensitivity on the left stick . I also mapped the trim to the up / down arrows on the key board . Easier to dab these to level the plane , than to use the Y + hat button on the controller .
