RC Glossary...

Understanding the Terminology of RC

RC glossary terminology will help you to become familiar with and better understand the world of remote control airplanes:

Adverse yaw: When an airplane is turned using only the ailerons, drag from the lowered aileron is more than that of the raised aileron. The extra drag makes the airplane yaw in the opposite direction of where the pilot intended to fly.

Aileron: Rolls the airplane right or left.

Angle of attack (AOA): The angle measured between the chord of an airfoil and a line representing the undisturbed relative airflow.

ARF (Almost-Ready-To-Fly): An airplane model that comes almost completely assembled and finished.

Buddy Box - When two transmitters are wired together using a trainer cord. This procedure is good when learning to fly, because if you get into trouble while flying, the instructor can fly the plane using his controls.

CA (cyanoacrylate): An adhesive that will cure rapidly. Used mainly for kit modeling.

Center of Gravity (CG): The model's balance point.

Control linkage: Servo movement is transmitted through this linkage to the control surface.

Control surface - Movable surfaces like the rudder, aileron and elevator.

Conventional Landing Gear - Tail dragger configuration. Airplane has two main gears up front and one gear in the.

Dihedral - When viewing the model from the front, you will notice an upward sweep of the wings. It is this upward sweep that gives the airplane its added stability.

Drag - The opposing force placed on an object as it moves through the air.

Elevator - That part of an airplane that controls up and down movement.

Elevon - A control surface on an airplane that combines the functions of an elevator and an aileron.

Electronic Speed Control (ESC) - Controls the motor RPM.

Servo - Used to move the control surfaces.

Stall - A point at which airflow over a wing is disrupted, resulting in loss of lift, and causing the airplane to drop

Tricycle Landing Gear - Landing gear that has a single nose gear and two main landing gear.
