WOW! that is just so wow.
Ready for me to prove you wrong?

1, if the plane is too light the CG still does matter. If you had a plane that wieghed 2 oz. and all the weight was in the tail, or the nose, it wouldn't fly coreectly, and pssibly not at all. Getting the CG right not only will make the plane fly better, it will make it fly more effiecently. Just because its flying doesn't mean its doing well. I guess if I throw a paper ball out the window, its flying for a little bit?
So CG matters if you want the plane to fly correctly and to the best of its ability.

2 if the plane is too heavy? No such thing. Just add enough power and the right wing and it will fly. After all thats how you are claiming that the cg doesn't matter, just add enough power and it will fly, you are contradicting yourself.

3 <see #2

4 Not enough power? well then the CG does matter, and so does the wing design. Again you contradict yourself.


If a plane weighed zero lololololol. Please please show me a plane that weighs zero MR.wizard.
Wing design is based on wings, that wiegh. Flying through air, in gravity. Its all part of the formula. Any other scnerio is not flying in the sense that these formulas are created.

Just because you sing, doesn't mean that you are in tune,
Just because you are flying, doesn't mean your doing it as best you can.


I am not an aeronautical engineer, but with common sense can point out that your theorys are flawed.
I think you need to re-word what your trying to say.
