I have a good college textbook on aerodynamics, and it says the lift created can be attributed to several factors, all of which contribute some degree of lift.
If you have been to a model airplane field and watched someone fly a plane with a totally flat wing with no curvature at all, then you realize that it will work.
When you watch someone hovering a model airplane 3 feet off the ground vertically, then you can see that the plane can fly perfectly with no wing at all (the wing actually becomes the propeller).
Stunt model airplanes have a symmetrical wing shape, and they fly perfectly right side up or upside down.
What it really boils down to is efficiency. If you are trying to lift say 100,000 lbs., and use a minimum amount of fuel doing that, then what should the wing shape look like? That my friend is the $100 million dollar question.
Any wing shape will fly, but how much power does it take to drag it through the air and maintain the lift that you want/need is the real question.
I love this circuit diagram. It is like many that I see on the internet, and actually makes more sense than most that I see.

Thank you UNIcastings, that makes perfect sense and also puts all the other explanations into perspective. They are ALL correct, only the efficiency differs. :bow:
And I also like the circuit diagram. I note that, in accordance with standard design practice, the circuit is protected from lightning and EMP by the "most expensive chip available". These chips are also employed to protect the fast-acting fuse in the output circuit of some systems. :big:

Hi All
When I was flying model airplane that question came up a lot. Flying small airplanes that used a piece of 1/8" flat balsa for the wing. I would tell them that I could make a barn door fly if I used enough power.
