Very cool. Sounds like I might be on the right track then. I was thinking about the CF rods and 2 aileron servos in the middle of the surfaces, which I would make about 3/4 span. I was also thinking about 1" square alum tube for the fuse. I love the large spinner idea! Also, I was thinking that an OS 50SX heli engine with a RPM range up to 20k would kick ass!

Oh, and of course being made of coro, the hinge lines would automatically be sealed. I was looking at the hardware store last night at a 48"x1/2"x1/8" aluminum strip that looks like it should make a good solid spar. Suprising light for the strength it would give.
