This project took a long time. It started a year ago when David
asked me if I could build a Fly-O-Plane. I was interested because
the mechanism was new to me. We both built several versions and
exchanged ideas until it was simple enough.
To my knowledge there are only 2 working Fly-O-Planes left in the world.
I would like to thank Lee Masons, the owner of the travelling one,
for his help and photos.
