Fairchild VZ-5
Turning propeller thrust through large angles proved a tempting idea to achieve VTOL flight, or at least STOL or super-STOL flight. Both Ryan and Fairchild built prototypes. The Fairchild VZ-5 was a similar layout except that a single T58 drove four propellers. The wing had 50% chord, full-span articulated flaps turning the flow 60 ° . The remaining 30 ° required for vertical takeoff was provided by rotating the air,:raft to that ground attitude. Both aircraft demonstrated the feasibility' of this approach but it had narrow operating margins which could be made worse by poor piloting technique.
