I agree with the direction of your questions. And I still do not have
answers to most of them.

The direction of my thinking is to:
1- tweak the fuselage design of V2.2 so it is more aerodynamic and looks
better,
2- do the engineering work to define the required strength of the various
parts of the fuselage, both for airplane and car with the goal of having a
fuselage that weighs 900 pounds (without engine & wings)
3- decide of the engine,
4- size the wings and canard.

Thanks for your thoughts.
