LISPRO Draw a line thru the center of the front of the 3/4" leading edge from side to side. Now slot your holes for CA hinges into the line & thru the 3/4" leading edge & into your 1/4" backup wood. Now either sand from the top of the aileron to the center line you previously drew & flip it over & do the same from the bottom of the aileron. Or use a knife to shave off the same from both sides & finish sand in your bevel. You'll find you will have plenty of aileron throw. Try it on a scrap piece first if you want.......Gene
