Glossary
NiCad. This abbreviation stands for Nickel Cadmium, the
chemical compound used in rechargeable batteries.
Nitro. Short for nitromethane, a fuel additive that improves an
airplane's high-speed performance. Check your engine's
instructions to determine the ideal nitro content for your engine.
Nose Gear. The part of the landing gear that is attached to the
nose of the fuselage. The nose gear is usually connected to the
rudder servo to help you steer the airplane on the ground.
Pitch Axis. The horizontal plane on which the airplane's nose
is raised or lowered. By adjusting the elevator, you can raise the
airplane's nose above the pitch axis (climb) or lower it below the
pitch axis (dive).
Pushrod. The rigid mechanism that transfers movement from
the servo to the control surface.
Receiver (Rx). The receiver unit in the airplane receives your
signals from the ground transmitter and passes the instructions
along to the airplane's servos.
Roll Axis. The horizontal plane on which the airplane's wings
are raised or lowered. By adjusting the ailerons, you can drop a
wing tip below the roll axis and cause the airplane to bank or
roll.
Rudder. The hinged control surface on the vertical stabilizer
that controls the airplane's yaw. Moving the rudder to the left
causes the airplane to yaw left; moving the rudder to the right
causes it to yaw right.
Servo. The servo transforms your ground commands into
physical adjustments of the airplane while it's in the air.
Servo Output Arm. A removable arm or wheel that connects
the servo to the pushrod. Also called servo horn.
Spinner. Term describing the nose cone that covers the
propeller hub.
Switch Harness. This switch is commonly located on the
fuselage and governs the on/off mechanism for the flight pace.
Tachometer. A device the measures the engine's RPM
(rotations per minute) by counting light impulses that pass
through the spinning propeller.
Thread Locker. A liquid that solidifies; used to prevent
screws from loosening due to vibration.
Torque Rods. Inserted into ailerons, these rigid wire rods run
along the wings' trailing edge, then bend downward and connect
to the pushrods.
Trainer Airplane. Designed to fly with high stability at low
speeds, a trainer model airplane allows new users some extra
reaction time as they learn to control the airplane's movements.
Transmitter (Tx). The device used on the ground to transmit
instructions to the airplane. Three transmitter modes are used in
model airplanes. The most common is Mode II, where the left
stick controls the throttle and rudder and the right stick controls
the elevator and aileron.
Vertical Stabilizer. The vertical surface of the tail gives the
airplane stability while in flight.
Wheel Collar. The round retaining piece that anchors wheels
in place on the axle.
Wing. Because wings provide the primary lift force on an
airplane, adjustments to the wings affect the airplane's
movements while in flight.
Yaw Axis. The vertical plane through which the airplane's
nose passes as it yaws to the left or to the right. The rudder
controls the yaw axis.
Z-Bend. The wire ends of pushrods have Z-shaped bends,
which attach to the servo.
