Construction began on November 3, 2008, in my basement where the airframe and fabric work occupied me during the long Upper Michigan winter. Then I moved to my hangar in May 2009 for painting, final assembly and engine break-in.
On September 1, 2009, it passed inspection and was ready for the maiden flight, which took place without a hitch. What an exhilarating feeling, that first rotation in a craft built with your own hands. The Challenger flies like a dream. Sporting a Rotax 582 powerplant, it has plenty of power for winter flying on skis, and amphibious float flying for the summer. Thanks to Dave Vandenburg, my EAA tech counselor, for his guidance, and especially my wife, Barb, for her assistance and unconditional support during this project.
