I flew Jerry's original one at a fly-in in Kentucky several years back, and it has to be the most pure "fun" 80 inch plane I'd flown. His original had 5" ailerons instead of the 3 or 4 inch options (I think those numbers are correct) offered in the kit. For power, he had a Webra 120 with a mouse-can pipe of sorts,.. it was 3 large cans (like harispray) put together with an outlet made from a small butane cylinder. With this setup, power was NOT a problem.
