Fight characteristics: Advancing the throttle above 2000 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 (3600 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 dual propeller, weight and balance issues, control combinations and many different wing tip styles. Terrain capability: Most people are surprised to see this craft drive from the water to the land much like a typical hovercraft. This was a very important consideration while developing the craft. It had to be self launching (land to water) and able to transition under its own power from the water back up onto the land. This is made easy by the positioning of the propellers. They are slanted …
