![]() The best choice is to find a position in which the boomerang wings tips are up. The traditional Australian boomerang has positive dihedral (an angle formed by two plane faces).Note that you only have to shape one face of the plywood. The quarter-round shape generally extends about 1/4″ (6 mm) from the edge, while the trailing edge extends about 1″ (2.5 cm) to 1 1/2″ (3.8 cm) into the material.Mark in on the top the distance that the contour retreats back from the boomerang’s edge to its top surface. A marking gauge can be used for this (or the old trick of holding a finger against the edge). The use of the asymmetrical design allows the Boomerang to fly faster and farther than the Baron using smaller engines, and seating the same number of occupants. Step 1: Keep the A4 sheet of paper in portrait orientation before folding the paper into half Fold the paper into half and UNFOLD it back. ![]() Lay out the leading and trailing edges of the wings based on which hand will do the throwing. The Boomerang was designed around the specifications of the Beechcraft Baron 58, one of the best known and most numerous twin-engine civilian aircraft.The bottom face of the wing is completely flat. Mark the two leading edges and the two trailing edges so you do not file them incorrectly. The leading edge is a quarter-round shape and the trailing edge tapers off the top of the boomerang like the cross-section of a typical airplane wing. As with airplane wings, the airfoils on a boomerang have a leading and a trailing edge. The direction the airfoil faces depends on the hand with which you throw. NASA has unveiled a boomerang-shaped spacecraft that could be the first to take flight on Mars to look for potential landing sites for future manned mission. Use ether a sanding block (and a lot of elbow grease), a belt sander, or an orbital sander to give each side of the boomerang an airfoil shape.
