Now you are asking to mix two different materials in a structural location. From what I have heard, that is a bad idea. Why not just use the Dr. Dean hinge method, detailed on Mark Langford's site, and make life easy and safe. This is one area that has been explored a great deal, and I believe that way too much time is wasted thinking of any new ideas. Incorporating these new ideas, while having merit, and making the builder look smart, will ultimately take a great deal of extra time, because now "Captain Kirk" you are going where no man has gone before!
I have a flying KR2 that has been taken down for an engine change that was supposed to take 3 months. This April will be one year. All changes take extra time. Weigh the advantages: you still only get 20 degrees up and 10 degrees down deflection; It will be with more resistance, as I have spoken to builders who have had a 601 with the aileron skin, and converted to hinge for better control harmony; and it will take longer because you will be making the blue print. My humble opinion is to find something else on the plane to express your individuality... Colin Rainey brokerpilot9...@earthlink.net EarthLink Revolves Around You.
