Open the aircraft.cfg file with notepad. These 3 lines -
prop_reverse_available = 1 //jdl, minimum_on_ground_beta = 1 // jdl and
minimum_reverse_beta = -14 // jdl are already there, you are replacing them. Delete them and copy/paste these 4 lines in their place. Save the file. (aircraft.cfg.) That's it - voila! - F2 stops the plane !
prop_reverse_available = 1 //jdl
minimum_on_ground_beta = 1 // jdl
minimum_reverse_beta = -14 // jdl
rotation = 1 // jdl
