|on this page 3... the ANIGRAND KIT of the Bell X-22 A VTOL|
The Bell X-22A was an experimental VTOL/STOL aircraft designed in the nineteen fifties. The US NAVY was interested in a VTOL concept, and Bell responded with the X-22. Later, Airforce and Marine corps were also interested so a "true Tri-service" project emerged. The X-22 had four rotating propellers in ducted fans driven by four turboshaft engines via a series of gearboxes. Two aircraft were built, the first flying March 1966. It had a number of problems and one proto crashed. Test program was stopped in 1974.
* Crew: 2
* Length: 39 ft 6 in (12.04 m)
* Span: 39 ft 3 in (11.97 m)
* Maximum takeoff: 16,755 lb (7,800 kg)
* Powerplant: 4x General Electric YT-58-GE-8D ducted turboshafts, 1,250 hp (932 kW) each
* Maximum speed: 255 mph (408 km/h)
Assembly is otherwise rather straigthforward.
I used superglue for the smaller parts and two-component glue for the fuselage.
The ducted fans take quite some effort to clean up and in some areas I
had to fill very tiny holes in the resin with a drop of superglue and baker's
salt. I used metal rods and drilled holes to get a rotatable strong joint
of the ducts to the fuselage.
I replaced the undercarriage legs
with pieces of metal rod made from paperclips. I also added what I think
is a fueldump pipe at the rear of the fuselage. The pitot tube was made
of a piece of rod. Otherwise, the kit needed no modifications.
For the aluminium I used Alcad II " highly polished " aluminium. It was applied over a acrylic black coating as stated in the Alclad instructions.
The provided decals are OK, but will
need a long time in water before they can be applied.
