Agreed. I read through all the posts in the biplane incidence thread and came to the conclusion that there were many ways to go. I even saw one design that used washout but only on the top wing. My current Biplane, a Circus Hobbies Reed Falcon has both wings set to zero as well as the stab but has 2 degrees up thrust. It flies great without any changes other then CG and a downline mix. The Goldberg and Dave Patrick Ultimates run zero on the wings as well but 2 degrees positive incidence on the stab.From where I sit I think my best plan of attack on this one is to make the bottom wing fixed and have adjusters on the top wing and stabs. Using a Hacker C50 motor with the 6.7:1 gearbox will also make thrust line changes quick and easy with the mount design I have planned.
