I used 3/4" diameter thin-wall 4130 tubing (because it's heavy), filled with lead. I went by the tire store and got a box of tire weights, melted some down in an old pot on a hot plate, and filled the tube up with lead.. I then epoxied the tube to the forward most edge of the aileron, running it through the nose ribs and reinforced on the ends with carbon fiber. They run almost full length, except for maybe 8 inches or so. They weigh in the neighborhood of 4 pounds each, but the ailerons are perfectly balanced, evenly distributed, and there's no extra drag incurred. > I was thinking that would be better aerodynamically that having something hanging down in the slipstream.< Yep, that's why I did it that way, and that's a big reason why I went with Frise ailerons, although now I have hinges hanging down about a half in inch.
