Swede,
When we first started flying SSC we all thought that the planes needed to be built right to the minimum wing area. When built to 400 square inches and 2-1/2lbs the planes do not fly well. They climb sluggishly and fall out of repeated turns. We thought we had a bad set of specifications.
Then a fellow showed up with a plane that had over 600 square inches. He could outclimb, out turn and just flat out run us all. His plane was flying on the wing at zero ange of attack. Ours were trimmed up so the engine could help the wing hold the plane in the air.
It is now routine to see 600 square inches up to 780 in a competitive SSC plane. The Cobras that I fly probably have too little wing area and they are at about 580 square inches.
Good luck and let us know how SSC goes up your way. There is more SSC info on
