One more thing. I ended up opting for thin-walled tubing with 1/8 music wire rather than the thickwalled tubing with thinner wire because I concerned with strengh. I don't think the gear ends up being too heavy and the plane does balance nicely (actually almost perfectly at this point). In the mock up I was using 1/4 inch thinkwalled alum tubing but decided this didn't look scale so opted for 3/16 tubing instead. The main leg LOOKS thicker in photos because of the wooden fair that was attached.
