RE: Crashed the Seagull Spacewalker II 120 and thinking of rebuilding
It would seem that there is more to this issue of getting out of a flat spin then just the wing... The two things that come to my mind are the CG location and control throw. If the CG is to far aft it would make it very difficult to come out of a spin. Secondary issue is the rudder control throw not enough (or for that matter surface area of the rudder) to counter the spin... I was always taught to point the nose down, neutralize the controls, cut the throttle and then full rudder in the opposite direction of the spin... If that didn't work then the CG was too far aft..
Just my two cents worth and always open to learning something new and different...
