Years ago we used to put stall strips on the leading of some pattern designs to make the wing stall and snap better. The strips were traingular shaped wood pieces glued to the leading edge to give it a sharp shape instead of blunt.
If you don't get the airfoils the same or close to the same it will have definate effect. I really thought this was going to be the problem, but within my ability to measure the leading edge and airfoils, they are the same.
I still believe my problem and those who have had the snapping problem have warped wings. I am going to twist some washout into my right wing.
Yes the nose weight should not be there. I was chasing the wrong cat with that one and that is why the problem remains with the additional weight.. Normally, this nose heavy, a plane would be so elevator insensitive all landings would be carrier landings. ie, no flaring ability. Mine still snaps with all that nose weight and less than 3/4" total elevator travel. And every landing is a controlled crash. I just have to have the snap at the point of contact with the ground,on every landing, you can see it start to break as it touches down.
I can't get this Edge past the snapping to get into 3D or High Alpha. It has to be the wing.
