Thanks for all of the replies so far!
One servo per control surface PERIOD. ( in your type plane). Servos have a limited rotation that is typically 60 degrees. They do not rotate 360 Ever!. NEVER do contrpl surfaces require servos to rotate anywhere close to 90 degrees.
You need to find somebody with a plane to SHOW you how these things operate. The forum cannot explain it nearly as well as SEEING an airplane.
