In February of 2008 Laurent Fabre of France submitted his design for a two-place tandem-seated vehicle,
able to fly, as well as travel on the road. His plan called for easy conversion from one use to the other, with only five or six
bolts to put in place and tighten - two for each wing and one or two for the elevator. The process was designed to take less
than 5 minutes! By May of 2008 he completed considerable experimentation on the basic design and now offers several
improvements. Here, in part, is his letter.
"Here is the latest version of my two-seater roadable aircraft. The tail is now tied to the frame, instead
of the wing, in order to lower the centre of gravity. A 1/10 scale model of this improved design has a 20.8 inch wingspan
and is 18 inches in length, when configured as an airplane. It is 15.7 inches long and 7 inches wide, when used as a car.
It is 6.9 inches high with the wings folded."
"You can see that at full scale, it would be the size of a small car! "
" I have obtained good gliding performance with this model, but it is sensitive to cross winds. For the tests,
its weight was 5.6 oz, without engine and propeller. Its wing area is 116 sq inches, and its wing loading is 7 ounces per sqare
foot. This wing is slightly auto-stable. I also tested this model with flaps and the lift was really improved, so it seems possible
to be able to fly with this sort of machine."
"And dont forget: Always 2 minutes to change from a car to a plane and vice versa!"
Thank you
Best regards Laurent FABRE
