When I put my breezy on the market in the spring of 2013, I wanted it to go to someone who would enjoy it for what it was and continue to give rides to all comers. In the 22 years I owned N7BK, I gave an estimated 500 rides. Carl Unger, who was one of the Breezy's designers, gave thousands of free rides over the years at the Experimental Aircraft Association's annual celebration of flight at Oshkosh. That prototype is now in the EAA Air Venture Museum. Unger and his co-designers, Charles Roloff and Robert Liposky, obviously wanted to create an airplane that was as simple as could be devised and still get off the ground-and safely back. Their creation was a naked, high-wing, tricycle-gear pusher with a pilot's seat mounted forward and a passenger seat behind that. The builder has to weld up the frame, and then put wings, gear, and a tail from an existing aircraft on it, shortening the build time considerably. N7BK was built by Bernard Kreifels in Sioux Falls, Nebraska. He used the wings of a Champ 7EC; generic Champ gear, tail, and stick; and a Lycoming O-290-D2 engine capable of 140 horsepower at 2,800 rpm for five minutes and 135 horsepower continuous at 2,600 rpm.
