Id love to have seen that Evan Fly . I think It is a good demonstration that lack of speed in an aircraft has its uses in operations the same as speed does. It must have been about as close as you could get to VTOL with the knowledge available at the time.
I have never seen one fly. I would love to take one out and fly it around. It is slow but I think it would be beautiful and fun to just joyride and cruise around in.
There's a kit plane 3/4 size of a real one. If I didn't hate doing dope and fabric work I would consider buying one. It stalls at 28 mph if I remember right.
Here's the link, several companies do a storch replica, oh I was wrong about the stall speed, the Australian one stalls at 21 mph, Carlson Aircraft has one that stalls at 19 mph!
