their  centered  position  during  installation.  The 
servo  connectors  are  keyed  to  prevent 
improper connection, but do pay close attention 
when  connecting  them  to  the  receiver.  The 
black wire goes toward the outside edge of the 

receiver case. Mount the switch harness to the 
side  of  the  fuselage  away  from  the  engine 
exhaust  (refer  to  your  model’s  instruction 
manual). Connect the red plug to the receptacle 
on the receiver marked B for battery.   

 

BINDING 

The receiver must be bound to the transmitter before it will operate. Binding is the process of teaching 
the receiver the specific code of the transmitter so it will connect to that specific transmitter. Once 
bound, the receiver will only connect to the transmitter when the previously bound model memory is 
selected. If another model memory is selected, the receiver will not connect. This feature prevents 
flying a model using the wrong model memory. 
 
1.    Switch on the transmitter, ensuring that the 
throttle control stick at its lowest position.   
 
2.    Connect the receiver battery to the receiver 
and wait until the Power Indicator LED on the 
receiver glows solid green. 
 
3. Press and hold the Binding Switch on the 
receiver for approximately 5 seconds until the 
Binding Indicator LED on the receiver goes 

solid green, indicating the binding finished.   

 

 
 

 

RANG & BATTERY TEST 

It is very important to check the transmitter will operate the model satisfactorily at maximum range. 
 
1.  In  order  to do  this,  place  the model  on  the 
ground and walk away from it whilst operation 
the swashplate controls. Check that the servo 
in the model operate without interference up to 
a distance of 33m.   

2. Check that the transmitter battery status LED 
is  showing  a  bright  red.  Do  not  fly  if  the  LED 
begins  to  flash,  as  the  batteries  need  to  be 
replaced or recharged. . 

 

ADJUSTMENTS 

The operating direction, neutral position and steering angle of each servo are adjusted. 
 
Caution: The basic linkage and adjustments of the fuselage conform to the fuselage design drawing. 
Be sure that center of gravity is at the prescribed position. 
 
Before making and adjustments, set all the servo reverser switches on the front of the transmitter to 
the lower (NOR) position (Switch the switches with a small screwdriver). 
 
Turn on the transmitter and receiver power switches and make the following adjustments.
