Joe,A number of years ago a very good friend of mine called the extensions "hooky". But after getting over it I still wanted the extensions for the better climb and glide beifits that should come from the extended tips. I did modify the building method a bit to make them less hooky.First I glued a piece of foam to the end of the outter spar and sanded it to the same surface as the spar face. Then layed up 2 layers of bid carbon fiber. Flip the spar over and sand the other side the same way and again layup the 2 layers of bid carbon fiber. I lapped the carbon fiber about 6" on to the sapr face on each side. Also over sized the layup in each of the other direction to cut and sand to size and shape with the wing shapping. after the wing was shapped and ready for the large lay ups to cover the wings and the carbon spar extensions were also shaped I then cut a v groove into the foam on the back edge of each face of the carbon fiber (4 places about a 1/4" each). I mixed up a flox mix and filled the grooves to the final surface and shaped to prep for final covering. This should make the entire wing tip a composite structure. Hope this is clear and really not a whole lot of work fo the results.Good luckJoe Horton Coopersburg, Pa ---------- Forwarded Message ---------- From: "cruzj12 at frontiernet.net" <cruzj12 at frontiernet.net> To: "krnet at list.krnet.org" <krnet at list.krnet.org> Subject: KR> spar extensions on KR2s wings List-Post: krnet@list.krnet.org Date: Mon, 7 Oct 2013 13:51:30 -0700 (PDT)
Has everyone building the 2s wings built the 12"extensions to plans or is there another method to get��equal or better results?
