Yes it is a kit with a foam wing core and balsa sheeted wings. Is carbine fiber better than plain ole glass or would glass work? Depending on the price and availability of the fiber I may or may not be able to get it. Would it go on the foam or on the sheeting and would I use the Zpoxy that I sheet the wings with or regular epoxy? I've never heard of carbine fiber. All I've used is different thickness of glass. As for the triangle stock, I agree, that would probably be a good idea. As I stated in my least message I plan on doing allot of overkill on the plane just for my flying style. All the rods will be 440 and like I said pull/pull on the rudder with cables.

As for the dual servo locations, should they be in the middle of the wing chord (chord-new word I learned recently :-p) about 1/3 from the end or nearest the root? They are full length ailerons on the stinger. I too am curious as to why the middle of the span is worst, I hadn't heard that before... Also, why no zbends? I would think they would be as good or better than a ball joint that can pop out of place?
Thanks all,
Rick
