GLOSSARY 

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

 

Aileron (AIL):

 Control surface at the left and 

right side of the main wing of the model. It 
usually controls turning of the model. 
 

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 usually controls up and down. 
 

Linkage:

 Mechanism that connects the servos 

and the fuselage control surfaces. 
 

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 is used to mean the reverse side. 
The opposite side is the normal side. 
 

Rod: 

A bar that connects the servos and the 

fuselage 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 motion to a rod. Servo horns come in 
various shapes. 
 

Stick: 

Rod for operating the transmitter. 

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.
