March 11, 2010 — We don’t know much about Afghan welder Mohammed Asef Nabizada, but we do know he built a twin propeller-driven ultralight in Afghanistan and flew it. Nabizada, 25, test-flew the craft in the Karakh district; which is in western part of the country. The test flight ended sooner than planned due to stability problems. EAA Senior Aviation Specialist Tim Bogenhagen, remarked, “Looks like the spirit of aviation and the desire to design, build and fly one’s own flying machine is alive in one of the most desolate and war-torn countries of the world.”
Dan Grunloh edits EAA’s Light Plane World e-newsletter and flies a trike. He observed that most pusher aircraft don’t allow for the tail boom and the engine to be mounted in the same area. Usually one is mounted above the other or designers go for the twin-boom configuration. Grunloh surmises that Mr. Nabizada employed a twin propeller design, thus allowing the rear fuselage section to extend directly out the back. Dan also observed that the engine uses a single shaft that translates power to the propellers via belts, which may cause reliability issues. One final thought from Dan: The aircraft “needs some trim stripes, but all in-all, an imaginative effort!” See more pictures and discuss at Oshkosh365.
