First Look


When the US Army issued the requirement for an Advanced Aerial Fire Support System, Lockheed won the contract with an advanced design - the AH-56A Cheyenne. The Cheyenne was a rigid rotor aircraft that employed fixed wings to augment lift in forward flight and a pusher propeller that further augmented forward thrust. The combination was to give the aircraft a 212 knot dash capability with an impressive array of range and firepower.

A fatal crash of one of the prototypes, delays in the development schedule, and the general political climate of the day led to the cancellation of the production contract, followed shortly thereafter with the cancellation of the overall program. The Army regrouped and issued requirements for a more conventional attack helicopter, and that competition led to the current AH-64 Apache.

The Cheyenne was indeed an advanced design. Its main rotor could still function like any other helicopter, but it didn't require the aircraft pitch changes to accelerate and decelerate, thanks to the pusher propeller. The pusher had full pitch control so it could adjusted for different levels of forward thrust, reverse thrust (for rapid deceleration) and in beta for normal deceleration, all without moving the nose off target. The aircraft was armed with a 20mm cannon in a ventral turret, additional firepower in the nose turret, an array of rockets, missiles, and external fuel tanks under its wings. Unlike many attack helicopters, the Cheyenne also featured retractable landing gear to further reduce drag.

Atlantis Models acquired the Aurora molds for their 1/72 AH-56 kit, currently the only production styrene kit produced in any scale to date. Molded in green styrene, this kit was designed as a quick build which was ideal for younger modelers. As you can see in the photos to the right, the kit is simple in layout. Anigrand did produce this kit in this same scale in resin, but I found that kit unbuildable.

After spending some time with this kit, I found that the Aurora and Anigrand kits have some interesting similarities and differences. Here is the summary:

  • It appears that the molds for the Anigrand kit were based upon the Aurora kit. There are a few differences to allow for casting in resin versus injection molding
  • The fuselages are essentially the same dimensions and shape except for the main rotor fairing - the Aurora kit's fairing is wider - and the Aurora kit has the ventral antenna housing that is missing on the Anigrand kit
  • Both kits have engine intakes that are too small
  • Both kits have the same squared-off exhaust duct found on the early configuration Cheyenne where the later configuration had the slight sugar scoop fairing
  • Neither kit have fuselage detailing for the APU or avionics bay ventilation
  • Both kits have the same integral wings and sponsons, which unfortunately means that both kits have the stub wings attached at too shallow of an angle incidence
  • The Anigrand main rotor head seems to replicate the later configuration where the Aurora rotor head is configured with the early system. The Anigrand rotor head was sectioned and integral with the rotor blades where the Aurora rotor head is molded separately from the blades making the Aurora rotor head easier to build and much less fragile
  • The Anigrand canopy in my sample had a fatal air bubble in the windscreen section where the Aurora canopy has ejector pin marks in that spot as well as on the rear of the canopy

The kit provides markings for the prototype aircraft 66-8828.

So if you're wondering if the Aurora kit was more accurate than the Anigrand offering, it is probably a safe bet that the Anigrand kit is based upon an Aurora kit. Can you accurize either kit? You bet. The Aurora kit will be easier to modify as a styrene kit, but a skilled modeler could also apply the same updates to the Anigrand kit. If you do elect to modify the Anigrand kit, the best thing to do is create several vacuformed canopies out of an Aurora/Atlantis canopy and go from there.

For me, this kit will be a fun project and I'm glad to see it back in production.
