I just bought a Speedster. I am keeping at the local airport until I'm proficient enough to land next to my barn.

The local FBO has enough hangar space for me if I keep the wings folded. Problem is, with gas in the tanks and the wings folded back, fuel leaks out of the filler caps.

I thought I could solve the problem if I had a device that would lift the tail wheel up so the longitudinal axis is parallel with the ground before folding the wings. Then I could wheel the airplane into the hangar by the same device.

Does such a contraption exist?
