I was glad to see some replies. Thank you.

What I'm doing is trying to build something similar to an old rubber powered design called the "Cruiser" by Charles Hollinger. Wing area will be around 320 sqin. Aspect ratio 5 to 1. No dihedral in the wing. I do intend to build in ailerons, however.

I have an O.S. OMA-3820-1200 electric motor for power, although I am starting to think this motor will be a bit much.
