| Using Underbelly Cone with Slots Facing Up On a | | | | of the underbelly cone will actually be the shape of a |

| the helicopters C.G. (Center of gravity). This | | | | angle of attack in the wing configuration will also be |
| continues as the helicopter lifts up.It will cost us | | | | adjustable. During rapid decent the inherent |
| about $10,000 to build a prototype of this concept. | | | | manufactured material will also be somewhat folded |
| Using a RC helicopter like one of these. Which will be | | | | so the wings will curl down and will mimic wing tips of |
| a smaller model of an existing helicopter. We also plan | | | | a "Swift" bird for high-speed dives. The swift can |
| to use some of the most recent micro helicopter | | | | dive at up to 217 mph.Now then as it comes in for |
| technology as practice versions. We figure a micro | | | | landing the wing is used as a barrier to trap air |
| version will cost us about $15,000 or less to perfect. | | | | underneath for an air cushion, for trouble free |
| RC Type Prototype platform to start tests prior to | | | | landings.The micro helicopter could be enough to |

| starting point: Cone Wing Shape: the aircraft is off | | | | six-inch rotor blades and six-inch wing when |
| the ground, which requires a lot of thrust, the cone | | | | extended. We are currently making pictures, artist |
| unhooks itself and spreads out into the shape of a | | | | renderings and a design. There are many uses for |
| wing similar shape to a bat. To show you the shape | | | | this micro helicopter concept for MAV style |
| of the wing. Do this: Take a piece of paper and | | | | surveillance and nano or insect size MAVs.On the |
| make a circle on it, six inches in diameter. Now cut | | | | larger model helicopters and actual full size human |
| that circle out. Then pick the center and make a dot, | | | | version units, the cusp of the cones slats will act like |
| then make one cut into the center. Now fold the | | | | slots or slats do on Short Take Off and Landing |
| circle into itself to make a Yarmulke. Now fold it into | | | | STOL Aircraft. This concept makes a lot of sense for |
| a cone. This is the cone we will use. Now unfold it to | | | | many reasons, we still are working through the types |
| the original circle. Now make another cut to the | | | | of materials to be used, strengths and manufactured |
| center exactly opposite of the first cut. But do not | | | | material concepts to provide for rigid shape while |
| cut it all the way thru, leave half and inch to keep | | | | flying, but bendable for cone structure yet, strong |
| the circle from becoming two halves. Now fold the | | | | enough to support the weight of the helicopter. |
| circle the other way but keep it flat, this is the shape | | | | Luckily the vertical strength of the cone can be |
