Yes I disagree. You realize that you can't throw this out without getting a reply. It's like saying all a dentist does is make cavities with his pick so he can put stuff in them.

------------- Any plane you design will almost certainly fly (within reason). -------------------

That is like saying that I can do dental work with a pickaxe. It is a foolish statement to say about anything much less about airplanes and (implied) the science of aerodynamics. Any airplane that is worth paying for or looking at doesn't fit the catagory of "within reason". Adequate airplanes fly extremely well, great airplanes ..............

It's simply a matter of how stably it flies (or, if you're seeking maneuverability, how unstably it flies). -----------

Stability and maneuverability are not necessarily mutually exclusive. Stability is a function of the difference between the Neutral Point and the CG of the machine. Airplanes of the model kind without stability augmentation cannot be flown in an unstable condition unless reflexes and eyesight are of awesome things to comprehend.

------------- As long as you provide enough thrust to create adequate lift, and as long as that lift is applied at the center of gravity of the plane, you're in business-----------

Well the thrust and lift thing is true but we in the aerodynamics field tend to call it a ---> rocket.

------------- If I understand flight correctly, you want the plane to fly with the fuselage nearly horizontal (pitched ever so slightly upward). That means, when you balance the plane with your fingertips under the center of the wings, just in-front of the halfway point of the wing chord, the plane should balance pitched slightly upwards. That's the center of gravity. Where your fingertips are represents approximately where the lift is (even though every square inch of the underside of the plane, fuselage, and stabilizer generates SOME lift.

It isn't the fuselage that needs to be nearly horizontal, the wing needs to be at the angle of attack which at the present airspeed will create the lift. Fuselage angle has nothing to do with it.

Where the airplane balances is where the center of mass, center of gravity as it is called, is located, and it is found better when the airplane is level when it is balanced. The fuselage tilt thing does not locate the CG itself. Simple Physics.

For a stable airplane the center of lift, or more precisely the Neutral Point, is located at some place froward of the CG. It is indeed a function of the wing, body, tail, etc aerodynamics.

I am not normally this mean spirited, but, before you try to make things seem too simple it would be best for you to read some material in order to have enough understanding to know what you are talking about.
