Ailerons to match
Denny, I haven't tossed any original ribs, but they are all pretty rough. I'll see if I need any of them and if not I'll pass them along to someone else. As for my wings. I will be running 17 foot spars with a squared off tip, the flap starts approximately 5" from the side of the fuselage and is 141" long, that leaves about 58" of wing remaining for the aileron. My plan is to use a shortened Cessna 150 flap as a frise style aileron, it has a 19.5 chord x 58" span, giving me 1131 in^2 of aileron surface. A standard cub aileron is 102" long with a chord of 13.5" for an area of 1377 in^2. The difference in area will be compensated for by my aileron being further out on the wing and thereby providing more leverage/force. The center of the stock cub aileron is 119" from the side of the fuselage, the center of mine is 174". A little rough math shows that my aileron should have about 1.2 times the leverage of a stock cub aileron. This is very rough physics, I'm not going to figure it out to the Nth degree, sorry that just isn't how I work. By my measurements my set up should actually have slightly more force than a Cessna 206 (which has very good aileron control), just considering aileron area and position on the span. The wing/aileron pics are of a 206 frise style aileron. To transform the 150 flap to an aileron it will have the forward flap track arm trimmed off and a pivot location aft of the leading edge will be drilled (conveniently there is already a rivet right where the pivot hole will be, drill it out and insert a bolt.) I will be making my own aileron hangers, similar to my flap hanger design to encompass the rear spar, not sure it the aileron force will need to be passed forward to the front spar like with the flaps, I'll look more at that as the project progresses. Thanks for the interest and comments. Joel
