When I built my Horizontal, Elevator, Vertical and Rudder, I purchased leading and trailing edges from Rider Hobby, which is a hobby store that specializes in very large scale radio control aircraft. The material of the edges is basswood, and surprizingly the shape of the edges were a near perfect match to the airfoil shape spelled out in the RR plans and drawings. It made my tail feather construction go so much easier and the results are fantastic (quality wise). This was after 2 previous attempts to get straight leading and trailing edges to the foam. Since my KR is a tail dragger, I covered the leading edges and aft 3 inches with kevlar to help protect the tail feather from pebbles and dirt kicked up during takeoff and landing. I had a minor accident while hanging a 500 watt halogen light in my shop. A metal cover from the lamp separated from the lamp while I was hanging it. The cover plate fell from 12 feet, and struck the leading edge of the right horizontal stabilizer. When I got down from the ladder, I expected the worse, but was pleasantly surprized to find zero damage to the horizontal at all, I never could find even a mark on it. Whew, lust lucky I guess, but I can't help but think that the kevlar had something to do with it.
Does anyone out there in NET land, know how to make an aileron straight and keep it straight? When I finished glassing the aileron, it was quite straight, now it is slightly bowed and wavy on the trailing edge. What is the secret?
