REFERENCE

GLOSSARY

The following defines the symbols and terms used in this instruction manual.

Aileron (AIL.)

Control surface at the left and right sides of

the main wing of an aircraft. It usually con-

trols turning of the aircraft.

Channel

Represents the number of control systems.

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 is

pointing down.

Elevator (ELE.)

Control surface that moves up and down on

the horizontal stabilizer of an aircraft. It usu-

ally controls up and down.

Linkage

Mechanism that connects the servos and the

fuselage control surfaces.

Modulation method

Two modulation methods are used with ra-

dio control: AM (Amplitude Modulation) and

FM (Frequency Modulation). Radio sets for

aircraft mainly use FM. Another method that

encodes and transmits the modulated sig-

nals 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 nor-

mal side. The opposite side is the reverse

side.

Proportional

Because today's radio control sets control

servos in proportion to stick operation, radio

control equipment is called proportional.

Rudder (RUD.)

Tail control surface that controls the direc-

tion of the aircraft.

Reverse (REV.)

With the servo reversing function, this is

used to mean the reverse side. The opposite

side is the normal side.

Rod

A bar that connects the servos and the fuse-

lage control surfaces.

Servo horn

A part that is installed to the shaft of a servo

and changes the rotating motion of the servo

to linear motion and transmits the linear mo-

tion to a rod. Servo horns come in various

shapes.

Servo mount

Fuselage base for installing a servo to the

fuselage.

Stick

Rod for operating the transmitter.

Throttle (THR.)

Part that controls the air mixture at the en-

gine intake. When opened (throttle high

side), a large air mixture is sucked in and the

engine speed increases. When closed

(throttle low side), the engine speed de-

creases.

Trim

A device that fine adjusts the neutral point of

each servo for safe flying. It is a mechanism

that corrects bad tendencies of the aircraft.

Up

Means up elevator. Direction in which the

trailing edge of the elevator is pointing up.
