Another deflected slipstream type, similar in principle to the Ryan VZ 3, the Fairchild M 224 achieved less success. It was a two seat high-wing monoplane with a single 1,024 hp General Electric YT58 GE 2 turboshaft engine driving four propellers each of 8 ft 5 in diameter. The wing had 50 per cent chord flaps and endplates. For vertical take off, it was intended to operate at a ground angle of 30 degrees. Control in the hover was by means of small tail fans above the T tailplane for pitch and yaw, and by differential pitch on the outer propellers for roll.
Tethered trials with the VZ 5 (56 6940) began on November 18th, 1959, but no free flights were made.
