This my be impossible to model I don't know. I was thinking of spending my perk points on some well known field modifications to my plane. For example the P-47 that was described in the post a few days ago with the over boost, the ground down rivets, and the polishing. You close trick out your P-47 and surprise a few people.

It's just an idea I've been toying with. It's probably not possible to model it. Would be kinda fun though.
