Hi, I can't get reverse thrust to work properly. Engaging it is easy but when I want to go back to idle the aircraft makes a violent jump forward. RT is mapped to a joystick button with FSUIPC (decrease throttle, repeat). Any ideas how to correct that? Thanks in advance...

Closing the throttle (F1) should result in a smooth transition from reverse to normal, don't add torque until the engines have settle down (about 20 sec). Maybe decrease throttle is not the right way to go from reverse to normal.
