I will as soon as I figure out a configuration that works. The ones I
have conceived so far might have power-output problems, even for one-
seat aircraft. There is a lot of math, with cyclic dependendies that
has to be worked out.

Personally I think what you're really needing is anti-grav drive.
There was a German guy working on the theory of it. Burkhard Heim was
his name. He died, though, before completing his work. But here's a
start:

Now you have to be able to read German and most physicists don't
really grasp his mathematics and system of physics, but you'd probably
make pretty good progress once you had the anti-grav drive part down
pat. The rest should be a piece of cake.

Anyway the American Institute of Aeronautics and Astronautics awarded
a prize for a paper on the concept:

Hmmm...never seen that before.

New Scientist mentions Sandia Labs and the US Military looking into it
though, so you may simply be too late (alas!).

Still, there may be a homebuilt market for similar technology, so your
efforts might not be entirely wasted.

My still-in-thought idea is far less exotic. Everything is based
Newtonian physics.
