Hobby Craft Plastic Model Kit North American F-82 Twin Mustang — 1:72

Manufacturer

Hobbycraft was a Canadian model-kit company known for producing a broad selection of aircraft kits, particularly subjects from the Second World War and early Cold War period. The HC1321 F-82 is part of the company's long-running 1:72 Twin Mustang tooling.

The history of this particular tooling is interesting. It is not the same tooling as the Monogram F-82. A detailed review of the Hobbycraft kit identifies it as descended from an Idea Model kit from South Korea released in 1985. Hobbycraft subsequently marketed its own version as HC1321, with the kit appearing in several editions during the 1980s–2000s.
Kit contents

The HC1321 represents the distinctive twin-fuselage F-82 in 1:72 scale.

The kit contains the major components required to build the aircraft, including:

Two complete fuselages

Two cockpits

Two pilot positions

Instrument panels

Twin engine nacelles

Main centre wing

Outer wing sections

Twin tail assemblies

Horizontal stabiliser

Landing gear

Propellers

Engine components

Centre-wing gun pack

External stores

Clear canopy components

Decals

Assembly instructions

A contemporary build review notes that the kit provides two separate cockpits and pilots, with different instrument panels and pilot poses. The centre wing includes a gun pack and a door that can be posed open.

The tooling is an older one and has raised rather than recessed panel lines, with some flash reported by builders. The original decals are also known to be showing their age on some examples.
The full-size North American F-82 Twin Mustang

The North American F-82 Twin Mustang was an unusual American long-range fighter developed during the final stages of the Second World War.

Rather than simply joining two existing P-51s together, North American developed an entirely new aircraft incorporating two Mustang-derived fuselages joined by a large common wing and tailplane.

The concept was driven by the need for a fighter capable of accompanying bombers over extremely long distances. A single pilot could not comfortably perform such missions for many hours, so the Twin Mustang had two crew positions, allowing the pilot and second crew member to share flying duties and reduce fatigue. NASA describes this long-range escort requirement as one of the fundamental reasons for the aircraft's development.
Development

Development began in 1943 while the Pacific War was still being fought.

North American's design became the XP-82, with two prototype aircraft constructed. The first prototype flew in June 1945, shortly after the end of the war in Europe.

The aircraft was therefore too late to perform the long-range bomber-escort mission for which it had originally been conceived during the Second World War.

Instead, it became an important aircraft during the transition from piston-engine fighters to jet fighters in the immediate post-war period.
Why two fuselages?

The twin-fuselage arrangement gave the F-82 several advantages.

The aircraft could carry a substantial fuel load while providing space for two crew members. On very long missions, the second crew member could take over flying duties or assist with navigation and other tasks.

The arrangement also provided a large central wing section that could carry weapons.

Although visually reminiscent of two P-51 Mustangs joined together, the F-82 was a purpose-designed aircraft rather than a simple modification of existing Mustangs.
F-82B

The early production F-82B was powered by two Allison V-1710 engines.

One particularly famous F-82B was aircraft 44-65168, named “Betty Jo.”

In February 1947, Betty Jo made a remarkable non-stop flight from Hawaii to New York, demonstrating the exceptional range of the Twin Mustang. The aircraft covered approximately 5,000 miles and remains preserved today at the National Museum of the United States Air Force.
F-82E

The F-82E was the principal long-range escort version.

By the time it entered service, however, the strategic situation had changed dramatically. Jet fighters were rapidly becoming the future of military aviation.

The F-82E consequently had a relatively short career as a bomber escort before being replaced by jet-powered aircraft such as the Republic F-84 Thunderjet.
Night fighter versions

The Twin Mustang found a more important role as a night and all-weather fighter.

The F-82F and F-82G versions incorporated radar and other equipment for night interception. These aircraft were particularly important because early post-war jet fighters did not always possess the endurance or equipment required for long-range night defence.

The F-82 therefore remained useful even as conventional daylight piston fighters were rapidly becoming obsolete.
Korean War service

The F-82 became especially significant at the beginning of the Korean War.

F-82Gs operated from Japan and were used for long-range missions over Korea. The type achieved the distinction of scoring the first U.S. air-to-air victory of the Korean War on 27 June 1950, when an F-82 crew shot down a North Korean La-7 near Kimpo. NASA specifically identifies the F-82 as scoring the first U.S. air-to-air victory of the conflict.

The aircraft was also used for:

Night interception

Long-range escort

Reconnaissance

Ground-support missions

Air defence

Rescue-support missions

The radar-equipped versions could patrol large areas and were particularly valuable during the early months of the Korean conflict.
Armament

The Twin Mustang could carry a substantial weapons load.

The central wing section incorporated a six-gun battery of .50-calibre machine guns on applicable fighter configurations. External hardpoints could also carry bombs, rockets and other stores.

The concentration of six .50-calibre guns in the centre of the aircraft provided a powerful forward-firing armament.

Radar-equipped F-82s could additionally carry equipment for the night-interception mission.
Performance

Representative F-82 specifications include:

Crew: 2

Engines: 2 × Allison V-1710-series piston engines

Power: approximately 1,600 hp per engine for the F-82G configuration

Maximum speed: approximately 743 km/h

Service ceiling: approximately 11,857 m

Range: approximately 3,606 km

Wingspan: approximately 15.62 m

Length: approximately 12.93 m

Maximum take-off weight: approximately 11,608 kg

Armament: up to 6 × .50-calibre machine guns plus external weapons

Specifications vary between F-82 variants, so these figures should be regarded as representative rather than applicable to every Twin Mustang configuration.
Alaska and cold-weather operations

The F-82 also had an important post-war career in Alaska.

Winterised F-82Hs operated in the severe Alaskan environment, where the aircraft provided long-range air-defence capability.

Maintenance became increasingly difficult as the aircraft aged and spare parts became scarce. By 1953 only a small number remained operational, with aircraft being cannibalised for parts to keep others flying. The last operational Twin Mustang was retired in November 1953.
NASA research aircraft

The F-82 also had an important scientific afterlife.

The National Advisory Committee for Aeronautics (NACA) acquired several Twin Mustangs for research. One XF-82 was used by NACA's Cleveland laboratory for ramjet research, with experimental ramjet-powered missiles launched from the aircraft.

NASA records that this research programme operated from 1948 to 1953.
Surviving aircraft

Several Twin Mustangs survive today.

Two particularly important examples are preserved at the National Museum of the United States Air Force:

F-82B 44-65162, displayed in the museum's Korean War Gallery in F-82G-style markings.

F-82B 44-65168 “Betty Jo”, displayed in the Cold War Gallery in the markings associated with its historic Hawaii-to-New York flight.

NASA also returned an XF-82 to flight after a lengthy restoration, making the Twin Mustang one of the more unusual surviving American piston-engine fighter types.
Historical significance

The F-82 occupies a unique position in American aviation history.

It was:

The last propeller-driven fighter acquired in quantity by the U.S. Air Force.

Designed primarily for exceptionally long-range fighter escort.

Adapted into an important radar-equipped night fighter.

Responsible for the first U.S. air-to-air victory of the Korean War.

Used for pioneering post-war aviation research.

One of the most visually distinctive piston-engine fighters ever produced.

Only 273 Twin Mustangs were built, making the aircraft relatively uncommon compared with the thousands of P-51 Mustangs produced.
