I am planning to make a biplane with wingspan 90 cm. Since I have to maximize the payload to be lifted so I am using S1223 airfoil in both wings.
But the pitching moment is coming to be highly negative. Suggest some measures of how to increase the pitching moment of whole plane.
What about using the reflex airfoil in horizontal stablizer.
