I take my wing off every once in a while when I want to take more than two planes to the field, but I try to keep mine together as much as possible. Once the components have had a few flights and the parts that are going to vibrate loose do so, then there is very little that will change inside the plane. This is a very simple airplane and there's not much to go wrong. Either way, I'd say mine gets a good interior inspection every couple of weeks which is more than enough for this plane. It's just so darn easy to take it out in one piece, fly, clean, and take it home in one piece. I love my Ultimate!
