Helping redesign a wing for a Helioplane. He wants to make the A/C an S.T.O.L type. Has a 230 S.I. wing and a 6 inch chord, using 09 glow power and weight looks to be about 12 OZ when finished. Ailerons are 9 S.I. each and way out at tip. No indication or outline on plans of size for real flaps.

We are hoping the A/C will take off vertically with the fuselage remaining horizontal.

However, what size in S.I. should the flaps be, and how much should they droop?
