Flaps initialization

If i resynch a flightmodel.cfg
with flaps, then if i delete all flaps in the AE, they still remain exisiting.
If i go back to main menu and reload a plane without flaps, they still remain
exisiting. Re-launching the game is needed to completely delete these
remaining flaps.

You need to click the Sync and Resync. This saves then resyncs the source
files to the project files. You do this anytime you make a change in the AE.
If you make a change in the cfg files directly only use the Sync.
