Anyone know why when I use the F2 key to reverse thrust it cycles on and off. Does it on all my aircraft. I have a Saitek X52 joystick set up.

Reverse thrust is cancelled if your throttle changes above idle. Check and make sure you are not getting power "wigglies" looking at the throttle in in the Win Gaming Device Calibration in the Control Panel.

 

In the axis sensitivity in FS assignments there should be some null to take care of any throttle noise in that axis.

 

I use a joystick button for the reverse function and it is set to repeat while I hold the button down since each click increase reverse thrust incrementally. I then give a burst of throttle to cancel it.

That fixed it! Thanks!
