The mixed up mess above, is just going to confuse a lot of people, as it says just enough to cause confusion, not enough to clear ANYTHING up. If it were presented properly... it would take about 600 k of ASCII text. (2 k is one double-spaced typewritten page)

The normal simplified explaination of how a wing produces lift is adequate for a basic understanding of flight. We present the simplified Bernouli explaination for the purpose of explaining that you need AIRSPEED to have the wing "create" lift. Inadequate airspeed and/or excess angle of attack means the plane falls out of the sky. (when the wing stalls)

The extra details, which are not needed to give a basic explaination of how a wing works, are ignored when using a flat bottom, high lift airfoil as the introductory example of how a wing holds a plane in the air. This common practice is not an intentional deception... its just an attempt to not overload a beginning R/C pilot with unnecessary information.

The full description of how a wing works takes the average Aeronautical Engineering student a couple of years to get right...
