Don't store them in the rafters of the garage or attic. The heat will destroy the airframes. Seen it happen. Guy puts a perfectly good airframe in the rafters of his garage. Comes back 2yrs later to sell the airframe. Pulls it out of the rafters and it just about falls apart in his hands. Covering was so dry and brittle, it was like really thin glass. Touch it and you'd poke a hole in it. All the wood was dried out to powder and sticks.
This is the ceiling of my master bedroom. Yes, I'm married.
