Forward swept wing?
B Mathews,
Your revision has cured most of the difficulties with the original. Yet, it still has plenty of novelty. I think it still may require plenty of lead in the nose and the landing gear mass so far out on the wings will still make it a bit sluggish in yaw and roll. The reflexed airfoil won't have a very high coefficient of lift so the high aspect ratio won't have much benefit. Reducing the length of the center panels about 30 to 50% would reduce the roll and yaw moments of inertia, improving roll and yaw response and make it easier to achieve balance too.
