Normal-----

A normal F16?
A normal Cessna 172?
A normal Flying Flea?
The application really defines the setup -
I just did two nice .40 powered kits for an article - very basic sport designs - CG's aprox 25%of MAC
very easy to fly . Not normal models for my own interest.
A given definition of "normal"-can be a bit of a canard also.
It is certainly interesting to see the various ideas as to what will an will not fly-- especially when the "proof " is referrenced to some text book.
Some formulas should read, "open book and close mind".
