I was just comparing the 1/4 Scale Sig Space Walker to the Great Planes Tiger Moth (I know its an ARF but just size comparing). The SW uses a 90-120 with an 84" span, 11-13lbs, and the Moth uses a 61-91 with a 71" span, 10-1/4 lbs and two wings. Both have similar dihedral. I'm betting the moth actually glides better.

Yeah okay, so I was tossing the idea of getting one around myself[sm=lol.gif]
