I installed an addon plane and would like to get rid of it, but there is no uninstall routine in Control panel. What can I do?
Assuming you are reasonably experienced with Windows, go to C:\Program files\Microsoft Games\Flight Simulator 9\Aircraft, identify the folder containing the plane you don’t want, highlight it and delete it. The first few times you do this, it is well worth creating a backup of the folder in case you nail the wrong one.
