RC dolly for small planes (e.g. 3Dlabprint 1:12 warbirds)

It was always difficult for me to hand launch small low wing planes, like the warbirds found at 3Dlabprint (small Spitfire, ME 109, Mustang, etc.)

On the other hand a fixed landing gear looks silly on these planes and so I always asked someone on our flying field to help me with launching.
But this also means, that I could not fly my birds, when I was alone.

A dolly would have been the solution. I didn’t want a huge one designed to launch big gliders, but a small one, which is dismountabl
