Concept Aircraft
Page Two

These aircraft were conceived because of different ideas that came up. For example, the Hoppy was designed because a friend of mine was wanting to build a two-place airplane. He needed an airplane that was safe, inexpensive and easy to build. Out of my conversations with him, the Hoppy was conceived. Will these airplanes ever be built? I have no idea but the drawings are here for you to see.

Moon Shadow

I like the idea of keeping the lines of an airplane very aerodynamic and clean. The pusher prop on this airplane allows the fuselage to have a natural laminar flow, increasing speed and giving very high performance. The only problem with the pusher configuration is keeping the propeller from hitting the ground on takeoff and landing. This is a four-place, roomy, fast airplane. It should be built of carbon fiber with wet wings. The wings have a high aspect ratio.The aircraft utilizes retractable landing gear and gull wing doors.

UnNamed Jet

I have been amazed at the radio controlled airplanes that are using real turbine (jet) engines. I believe, working with the designers of some of these small turbine powerplants, we can design an efficient, inexpensive and safe turbine for a homebuilt aircraft. The idea of fixed gear appeals to me on this design and top, cantilever wing gives great views to the pilot and passengers. I really think jet propulsion is the wave of the future for the homebuilt arena. Here, again, is a wide-body aircraft (fuselage width is 5.68 ft) with an aisle between the seats for the four passengers. There is also room on the panel for a laptop computer to hook up to your GPS for exact navigation. The airplane is built from carbon fiber with a wet wing. The wing has no dihedral but the horizontal stabilizer does to keep it out of the jet's exhaust.

Wingspan 36.76 ft  
Wing Chord 73 inches root, 35.08 inches tip  
Length 24.17 ft  
Height 10.52 ft  
Power Jet Turbine  
Gross Weight 3000 lbs
