Has anyone done one of these with a gas engine? I have an SPE 26cc engine in mine and man is it nose heavy. It's taking about 3 pounds 2 ounces to get the balance correct using a Great Planes C.G. Machine, according to the instructions (5 1/2" back from LE of lower wing) . That's with the weight behing the tail wheel, so I imagine I'd have to mount it just inside the tail cone. I'm worried that much weight at the tail would cause problems for the tail wheel retract. Moving the batteries would hep some, but I don't think it would help a lot.

Any thoughts?
