The only side by side fully aerobatic (+6, -4)*Biplane! Carries 40 gallons and 80 lbs of baggage.*The fuselage creates 20% of the lift. Ailerons all droop as flaps (flaperons). New wings in 2006. Enlarged the ailerons (40%)*and the rudder (50%). I also own the (SNS 7) design along with Marc Winnig.
