Mong MS1 Sport
The Mong MS1 Sport is a 1950s American homebuilt biplane design with over 400 sets of plans for the aircraft have been sold. Design and development. The first Mong Sport was built as a personal aircraft by the designer Ralph Mong, Jr, and plans for homebuilding were provided afterward, due to demand. The original biplane was built around a Continental A65 engine. The biplane has the unique feature of lift struts placed between the lower fuselage frame and the upper wing I strut attachment. The biplane did not require expensive, drag producing support wires, using steel tubing  instead. The fuselage is steel tube with aircraft fabric covering. Operational history. In the mid 1960s, a biplane class was added to the Reno Air Races. The Mong Sport met the basic qualifications, and has been extensively modified over the years by builders to be used as a biplane racer. In 1965, Bill Boland won with his ""Boland Mong"" at 148 mph and again in 1967 and 1970 with speeds of 151 mph and 177 mph respectively. The "Mongster" won the 1968 Biplane class of the Reno National Championship. "Long Gone Mong" won in 1987 and 1989. A highly modified  Mong "Phantom" with carbon fiber wings won in 2006 with a speed of 251.958 mph, and has recently raised the record to 284.454mph. Aircraft on display.
