I increased my stub wing 11 inches on each side. My main reasons for doing this were to increase my flap area and effectiveness and to increase wing area due to the weight of my engine. I increased the number of vertical pieces between the spar caps and then completed it per plans. I then added 1/4" plywood to the rear of the main stub spar that extends just beyond the edges of the Diehl gear attach brackets. These brackets have been moved outside the diameter of the prop for drag reasons so the additional plywood is almost full length of the spar. Outer wings are stock and will be the Diehl skins. Realize you are talking about the main structural component of the aircraft so any change to this should really be thought about. I don't think a 1' extension is extreme but since I am not yet flying you might want to do a search of the archives and see what others have done. Good luck, Stephen [email protected]

If so how much was added to total length? I would like to add a total of 12".. Is this possible? I would also be leaving the outer spars their length.
