How much carbon fiber is enough? I built a 6 inch extension to my tail surface the way that Mark describe below. ?When I attach the new addition to the airplane I will t88 glue it to the tail and cover in carbon fiber. I want o overlap the old and new with carbon fiber. ?How far do I want to overlap? ?Do I recover the entire horizontal stab to compensate for the additional stress created by the additional surface? ?
^^^:Mark wrote:That will help, but the same material further aft on the ends of the stabilizer (leaving the elevator the same size) would be more effective, and easier to build, since it's simply an extension of the existing airfoil, and the existing h/s would act as your sanding template. I'd make it out of foam sanded to shape and covered in two layers of carbon fiber, personally.? It would be out of the prop stream and in smoother air, if that's even a consideration.^^ Joe Nunley?CW2 US Army RetiredBaker JROTC Instructor?Baker Florida?
