Wow! Great film! I watched the whole thing.
I did a complete ground-up restoration and recover of a 1943 Taylorcraft L-2M, almost identical and designed by the same person as the Cub. This really takes me back and reminds me why it took six years to do the job single handed. My T-Craft had Cub wheels and brakes, those gawd-awful expanding-shoe things (shown in the film) that barely would hold the plane in place for engine runup.
The "model airplane" connection that makes this thread legit is that my years of model plane building came in handy doing the woodwork and covering the 37-foot wing, just like doping a model wing, but bigger. And with rib stitching.
