Tests were made to determine effects of single- and dual-rotation propellers, tilting propeller thrust axis down 5 deg, raising horizontal tail, and combining tilt and raised tail. Results show that the propeller may be used as a speed control. Disadvantages are significant changes of stability and control characteristics, which, however, can be held within limits of safe operation if a negative propeller thrust is restricted by limitation of power output of the engine. Other undesirable effects may be minimized by proper design of airplane.
