The Mong MS1 Sport is an early original homebuilt biplane design from the 1950s. Over 400 sets of plans for the aircraft have been sold.[1]
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.[3]
The original biplane was built around a Continental A65 65 hp (48 kW) engine. The biplane has the unique feature of a single lift strut placed directly forward of the pilot at a sacrifice of forward visibility. The biplane did not require expensive, drag producing support wires, using steel tubing instead.[4] The fuselage is steel tube with aircraft fabric covering.[3]
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.[5] The Mongster won the 1968 Biplane class of the Reno National Championship.[6] 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,[7] and has recently raised the record to 284.454mph.
