But then remember to copy/move your renamed plane back to your PLNPILE folder in flight3. Then when you restart FU3, your old plane and the new-named plane will both be available.

Ah, methods, methods...I have a backup folder in my plnpile folder and copy the original there FIRST! Then I can freely play with my 'live' copy as it saves a heap of time with updating and checking ;)I agree that with models, I check them out with Modelviewer or similar first, to avoid CTDs.With aircraft, CTDs are a way of life, and 10 iterations of a flight model isn't unusual in one evening :-rollPS Hi Rob :-waveRegards,Jon Point
