Reason why i said you'd spend perkies to get a 30 sec repair.
Combat damage to the wings, such as bullet holes, structural weakness from taking fire, etc would not be repaired.
Only thing that would be repaired is things like, elevator/aileron replacement, and patched up fuel tank/oil leak.
PW's would not be treatable through this service.
Perks spent or not, recovering or replacing control surfaces such as elevators, rudders and ailerons are fabric covered (since there would be a need for a ridiculous amount of counterweight if they were metal clad) and are not the easiest thing to replace in a jiffy. Recovering fabric surfaces is not a quick thing to do and more then likely if a control surface is damaged or missing, the related control cables, etc will also be destroyed as well, meaning that they are too short to reattach and would require fishing new cables, etc throughout the structure which is time consuming to say the least once the wings, etc are skinned.
Making it possible to spend perks to repair planes quickly would just be a concession for those requiring instant gratification and would be a giant step towards making this game more "arcade-ish" and not requiring players to learn more ACM or plan their engagements more carefully. In addition, it would only benefit those looking to "get their name in lights", pad their score or rack up lots of kills without worrying whether or not they are flying prudently enough to keep their plane intact. Since the planes are already free, the score hounds are the only ones that would benefit.
An easier thing to do would be to make sure your plane is not tore up when and if you rearm.
