So is it tested and understood that the farther out on the wing, the less of this "cusp or tuck" the better, as far as on the aileron goes? Has this been proven on other airfoils? Would you fill in the tuck, keeping the cord the same? Steve McGee Endeavor Wi. USA Building a KR2S widened. lmc...@maqs.net
