You are afflicted with the same problem as many other modelers. I have a two car garage but very little of it is used for shelves and storage. Half of it is my model shop so one car sits outside. I use the walls of the entire garage. I hang glow aircraft, engine up, and the electrics, motor down, on hooks made to fit. The planes are flat against the wall and take up little room. Now if you will tell me how to store three sailboats, without unrigging them, we'll be even.
