Build a Wing Washout Jig

Originally by Fly RC Staff for Fly RC Magazine

When building any model airplane, it is important that the wings have a bit of washout; and if the plane is going to fly properly, the wings should be washed out equally on both sides. During scale model builds, lift struts are used to support the wings of most high wing monoplanes. When building the lift struts, it’s much easier to get a good setup if the wings can be physically supported in the correct position to ensure a proper setup. Building larger models with substantial structures, incidence meters can be used to compare the angle of attack from root to tip. On lightweight park flyers, incidence meters are usually too heavy and cumbersome to work effectively. For that reason, the washout jigging device described here was developed.
