Here is another batch...Sig Cubs are really labor intensive. To add to that, I decided to do scale Frise ailerons. They really work much better than the stock "boards" and really cut down on adverse yaw. On a stock Sig Cub, when you apply aileron, the nose swings the opposite way of the turn and requires a lot of rudder to keep it coordinated. With the Frise ailerons, air is drawn up through the pocket created by the airfoil shaped ailerons and the trailing edge of the wing...it's aerodynamically more efficient lessening the adverse yaw and the amount of rudder needed.
