The Griffon Lionheart is an American single-engined, six-seat biplane designed and produced in kit form for home building by Griffon Aerospace of Harvest, Alabama.
The Lionheart is based on the Beechcraft Staggerwing biplane of the 1930s; [1] but unlike the steel tube, wood and fabric construction of the Staggerwing it has a composite structure. [2] The Staggerwing has strut-braced wings but the Lionheart has cantilever wings with a total area about 20% less than the wings of the Staggerwing. [1] It is powered by a 450 hp (336 kW) Pratt & Whitney R-985 Wasp Junior radial engine with a three-bladed propeller. It has a retractable conventional landing gear with a tailwheel. [2] The enclosed cabin is slightly longer than the Staggerwing's cabin to allow room for the pilot and five passengers, and it has a split airstair access door on the port side. [2] [3]
The Lionheart first flew on 27 July 1997 and was first displayed in public at EAA AirVenture Oshkosh a few days later. [1] [4] Five kits were sold by April 1998, and two of the kits were completed by 2001, with another almost complete. [1] [2] [3] As of August 2011, three Lionhearts are registered in the United States, with another example on display in an aviation museum at Tullahoma Regional Airport in Tullahoma, Tennessee. [5] [6] Kits are no longer being produced. [1]

General characteristics
Performance
The Beechcraft Model 17 Staggerwing is an American biplane with an atypical negative wing stagger. It first flew in 1932.
The Pratt & Whitney R-985 Wasp Junior is a series of nine-cylinder, air-cooled, radial aircraft engines built by the Pratt & Whitney Aircraft Company from the 1930s to the 1950s. These engines have a displacement of 985 in3 (16 L); initial versions produced 300 hp (220 kW), while the most widely used versions produce 450 hp (340 kW).
The Howard DGA-8, DGA-9, DGA-11, and DGA-12 were a family of four-place, single-engine, high-wing light monoplanes built by the Howard Aircraft Corporation, Chicago, Illinois from 1936.
The Curtiss P-6 Hawk is an American single-engine biplane fighter introduced into service in the late 1920s with the United States Army Air Corps and operated until the late 1930s prior to the outbreak of World War II.
The Vultee XA-41 was originally ordered as a dive bomber. After combat experience led the Army Air Corps to believe dive-bombers were too vulnerable to enemy fighters, the contract was amended to change the role to low-level ground attack. Although the XA-41 was a potent weapons system, the design was overtaken by more advanced technology, and never entered production.
Griffon Aerospace is an aerospace company located in Madison, Alabama with additional offices located in Fort Bliss, TX. Griffon designs, develops, and operates aerospace systems including manned and unmanned aircraft, UAV ground support systems, and advanced composite structures. Griffon has produced over 6000 unmanned air vehicles for a variety of customers from US DoD, Foreign Military Sales, Commercial Businesses, and University research labs.
The Gregor FDB-1 was a Canadian biplane fighter, designed in 1938 by Michael Gregor and manufactured by Canadian Car and Foundry. Despite having some advanced design features such as flush rivetted all-metal construction and a retractable undercarriage, the final generation of biplane fighters was being supplanted by monoplanes and the Gregor FDB-1 was obsolete before it flew. Despite the Royal Canadian Air Force's desperation for modern fighters, the sole example remained unsold and was eventually lost in a fire in 1945. The Gregor FDB-1's model designation stood for Fighter Dive Bomber indicating its intended roles.
The Great Lakes BG was an American carrier-based dive bomber of the 1930s. Designed and built by the Great Lakes Aircraft Company of Cleveland, Ohio, 61 were used by the United States Navy and United States Marine Corps from 1934 to 1940.
The SIAI-Marchetti SM.102 was a 1940s Italian light transport cabin monoplane designed and built by SIAI-Marchetti.
The Weatherly Model 201 is a 1960s American agricultural monoplane designed and built by the Weatherly Aviation Company of Hollister, California.
The Hall XFH was an American fighter aircraft built by the Hall Aluminum Company. It was the first fighter with a semi-monocoque metal fuselage.
The Bach Air Yacht was a trimotor airliner produced in the United States in the 1920s. Typical of its day, it was a high-wing braced monoplane, with fixed tailwheel undercarriage. Unusual for airliners of the late 1920s, the Air Yachts were constructed almost entirely of wood with steel fittings, undercarriage, and struts. Different models were powered by varying combinations of Wright, Ryan-Siemens, Kinner, Comet, and Pratt & Whitney engines, a large engine in the nose of the aircraft, and two smaller "helpers" under the wings in nacelles supported by struts. As with so many aircraft companies of the late 1920s, the Bach Aircraft Company succumbed to the Great Depression, thus further development of the Air Yacht was abandoned after the 3-CT-9.
The Boeing Model 6D, a.k.a. Boeing Model 6E, Boeing B-1D and Boeing B-1E, was an American pusher biplane flying-boat built by Boeing between 1928 and 1929.
The McDonnell XHJH Whirlaway, aka McDonnell Model 37, is a 1940s American experimental transverse-rotor helicopter designed and built by McDonnell Aircraft Corporation for the United States Navy and was the largest helicopter at the time, as well as the first successful twin-engined twin-rotor helicopter in the world.
The Waco E series is a small family of American-built cabin biplanes built between 1939 and 1942, which differed primarily by engine installation.
The Bird Wing or later, Bird Wing Imperial was a light sport biplane of the 1920s and 1930s.
The Lamson Air Tractor was a prototype American single-engined biplane agricultural aircraft of the 1950s. Two examples were built, with the first flying in December 1953, but the type did not enter into production.
The Zenith Z-6 is a single engine biplane U.S. airliner built in the late 1920s. Its cabin, in the fuselage immediately behind its radial engine, holds five or six passengers depending on engine power. It is flown from an open cockpit further aft. Nine were completed and one has been restored to flight.
The Pitts Samson was an aerobatic biplane designed by Curtis Pitts in 1948.
The Waco D Series was a series of military biplanes created between 1934 and 1937 by the Waco Aircraft Company for export to countries other than the United States. The three letter designation indicated the engine, airframe, and series. Armed versions had a -A suffix.
