Nice Cave! You sound like my dad and I. We have about 9 built but unflyable models. With the completion of the man cave, we will have no reason not to get them flying. The unflyable airplane that we have that i really want to get flying again is our 1/3 scale Flybaby Bipe from Balsa USA. It needs recovering. Dang covering is so expensive though! We also have about 9 or 10 flyable models. And two 1.20 size Extra 300s's that are need to be built.
