I have seen on a few of the screens (aircraft data screen - particularly the SPAD), that wingfold can be done using button 5 (num pad). Is that button also linked to wing fold for the Navy Phantom, the Intruder, the Navy A-7 (Corsair), the Crusader and the Viggie?
It's too bad that there are only ten animation slots available for a modeled aircraft - if there were twice that many, can you imagine all of the neat stuff we could add to new airplanes? The mind boggles...
All the YAP planes that have the mod, have the animations already assigned. The key assignment is on the given aircraft hangar screen, or you can look in the given aircraft dataini.
