Nicely done kit for it's time. Features movable main rotors, moving elevators and rudders, opening rear taches, good cockpit detail, crew of two, optional position boarding stair/door and more. The kit has never been started. Internal factory sealed bag including decals and instructions. The Rotodyne first flew in 1957. The purpose was to create the first true vertical take-off airliner that could operate from an area no larger than two tennis courts with a full load. The Rotodyne flew at up to 191 MPH with a range of 450 miles and a payload of 48 passengers or 5 tons of freight. Despite the excellent performance and a larger design in the works, the RAF never placed an order and BEA never placed a firm order. The project was discontinued in 1962.
