Boomerang

InstructionsWill work best if scaled to between 20 x 20 and 30 x 30 centimeters and a thickness of about 3.5 to 4.5 millimeters.Mine has a wingspan of 215 mm and is 3.5 mm thick.You can enhance wind stability, spin retention, and distance by taping a small weight (coins or washers will work well) to the first arm as shown in the photo.Boomerangs are quite finicky regarding warping and bending. If your boomerang is not perfectly flat, try to flatten it by heating with a hairdryer or heat gun, and then clamping it to a flat surface.
