Universal Hovercraft TW-1 Tandem Wing Hovercraft, Hoverwing, ground effect, WISE, WIG, SEV

Fight characteristics: Advancing the throttle above 2,000 RPM with bring the craft up on cushion and begin a slow acceleration. This rpm is used to depart the landing zone. Advancing the throttle to full (3,600 rpm) will rapidly accelerate the craft. On a calm day the craft will achieve 50 mph in just 6 seconds or 350 feet. After the craft is airborne it flies similarly to a small airplane. Moving the joystick left causes a slight bank and shallow turn. Because the craft is not fitted with ailerons it skids thru the turns much like a hovercraft. At cruise speed (45 to 50 mph) the craft rides very smooth. You can pass over waves without feeling any effect. Scale modeling: Nearly 25 scale models were constructed before the first tandem wing craft assembly began. This is the way we test most of our craft. It is much easier to make corrections in a styrofoam model than in a full size prototype. We tested wing angles, surface areas, 2,3 and 4 wing models, propeller angle, single propeller and dua
