The best explanation by far on how the flight controls on an aircraft
work was written by Maximilian Foster in OUTING Magazine May 1909.

Republished in the book "Early Flight from Ballons Tp Biplanes"
Published in 1987 by Castle ISBN 1-55521-227-1

I was very impressed when I read this 11 page article with pictures
of the Wright brother and Glen Curtiss flying.

I have searched for this book on Google so apparently it is very rare
book. I found a copy in the $5 book store in Semi Valley California.

If I get some interest I will scan part of  it and OCR convert it to
text.

"As to Frise aileron - Frise's design is a very specific geometry to
achieve a protrusion of the aileron's lower edge below the wing to
add drag when the aileron is up, and minimize adverse yaw."

It works extremely well on my C182.

Basically it reduces the need for a rudder during turns. The rudder
control was basic to the Wright invention.

Paul,

Thanks

There is another article in there by the same author. He has an amazing ability to
explain highly technical subjects like the center of pressure in easy to understand terms.
It is almost like you are reading a novel.

This one is tittled "The Highway Of The Air" Page 225
