Well congratulations vh2 and glad to see you have had some success with the project and hope there is much more.
I do completely understand the desire to work through some of the challanges of projects sometimes like these even if they may not be the most practical. That makes the successes so much better
Thought you would get a kick out of this picture made in the late sixties at my fathers house and with an airplane I flew in the same way with the same engine, a bottle carb OS Pet 099 it was just a simple thing I made up and use to toss it off a walk bridge over a gully at his place in the desert when I visited him. It to had no landing gear and was flown with just ailerons and elevator, I just wired the throttle open.
