[1][2] After Haufe's earlier Buzzer was deemed less than successful, due to the insufficiently reliable Nelson Aircraft engine, Haufe retired that design and designed a new aircraft, which became the Buzzer 2.
The landing gear is a fixed monowheel and two wing-mounted outrigger wheels that support the wing during taxiing.
The engine is a Curtiss snowmobile engine that turns at a maximum rpm of 6000, powering the propeller through an oil-immersed 2:1 chain reduction drive, giving a propeller speed of 3000 rpm.
[1][2][4] Haufe reported that the aircraft uses 600 ft (183 m) to take-off and climbs at about 500 feet per minute (2.5 m/s).
The aircraft was still on the US Federal Aviation Administration registry in July 2011, registered in the Experimental - Amateur-built category.
