There is nothing on this plane that needs to be improved, or changed. Dual aileron servos are really not needed, as this is not a 3D plane. The Super Kaos is a time tested design that has zero bad habits. It will land at a walking pace, and do just about anything you ask of it. I have built and flown probably 6 to 10 of them over the past 30 years, with no modifications, I see no need to fully sheet the wing, but it can't hurt. Keep it light and provide good power and it will reward you with many years of enjoynment.

Congrats
