Glossary
The following defines the symbols and terms used in this instruction manual.
Aileron (AIL)
Control surface on the left and right sides of the
main wing of an aircraft. It usually controls
banking of the aircraft.
Channel
Represents the number of control functions. It
can also represent the number of servos that
are operated.
Down
Means "down" elevator. It is the direction in
which the trailing edge of the elevator moves.
Dual Rate (D/R)
Reduces the servo travel by flipping a switch.
Elevator (ELV)
Control surface that moves up and down on the
horizontal stabilizer of an aircraft. It usually
controls up and down. (Altitude)
Linkage
Mechanism that connects the servos and the
fuselage or wing control surfaces.
Modulation Method
Two modulation methods are used with radio
control: AM (Amplitude Modulation) and FM
(Frequency Modulation). Radio sets for aircraft
mainly use FM. Another method that encodes
and transmits the modulated signals is called
"PCM".
Neutral
Means the neutral position. It is the state in
which a transmitter stick returns to the center
when not operated.
Normal (NOR)
For the servo reversing function, it is the normal
side. The opposite side is the reverse side.
Rudder (RUD)
Tail control surface that controls the direction of
the aircraft.
Reverse (REV)
With the servo reversing function, this refers to
the reverse side. The opposite side of reverse is
the normal side.
Rod
A wire that connects the servos and the control
surfaces.
Servo horn
A part that is installed to the shaft of a servo
which changes the rotating motion of the servo
to linear motion and transmits the linear motion
to a rod. Servo horns come in various shapes.
Servo mount
Base for installing a servo in the aircraft.
Stick
Control for operating the transmitter.
Throttle (TH)
Part that controls the air mixture at the engine
intake. When opened (throttle high position), a
large air mixture is sucked in and the engine
speed increases. When closed (throttle low
position), the engine speed decreases.
Trim
A device that fine adjusts the neutral point of
each servo for safe flying. It is a mechanism
that corrects unbalanced tendencies of the
aircraft.
Up
Means "up" elevator. It is the direction in which
the trailing edge of the elevator moves.
