Wilhelm Bretfeld was one of Germany's most creative boomerang designers. As a young boy, he set an official world record in small gliders by launching one that went 37 kilometers with a flight that exceeded 3 hours. Wilhelm became interested in boomerangs at an early age and developed his own models. Most of the early models were very large. Wilhelm was the first to discover that the secret to long boomerang flights was to have the lift arm longer than the dingle arm. In the 1970s, when the ret of the boomerang world was struggling to reach 20 seconds, Wilhelm was achieving 30-35 seconds using his early prototype MTAs. These early MTAs were very large and had no dihedral or angle of attack. Instead, they had lots of lead weights pounded into the blade tips and the undersides were scooped out to add plenty of camber. These MTAs did not climb very high. Instead, they had long duration flights because the airfoils were very efficient and the large heavily weighted blades had plenty of inertia to overcome aerodynamic drag losses. You can read more about Wilhelm Bretfeld on his Memorial web page.

This Bretfeld Sport Omega was made out of Aircraft Birch plywood and painted with enamel paint n both sides. A lead weight is embdded in the elbow and on both tips. Signed on the elbow underside and with the following message, written to Brother Brian Thomas: "dedicted by Wilhelm Bretfeld to the boomerang friends down under in July 1998". I have not test thrown this boomerang, but it feels well balanced and probably has a range exceeding 50 metres. Bretfeld boomerangs are very rare and every one I have thrown has been a superb flyer.
