I agree with your logic, but have to say that a SSE has such an efficient wing that the need for flaps in any circumstance is near to zero. When landing it's such a floater that the problem is getting the thing to leave the sky!

I also reckon increasing the wing loading to the extent that it will tip stall will create a situation where it will have the aerodynamics of a brick! I have never had a model that exhibits such a lack of tip stalling or snapping when you don't want it to.

Anyhow, whatever you do it would be interesting to hear from you when you fly the model.

Please keep us informed!
