In helicopters, there is generally enough room on 
the servo tray to achieve the necessary separation. If 
necessary, a mount can be made using clear plastic to 
mount the remote receiver as shown below.
Other Important Installation Tips
1. Mounttheservosusingrubbergrommetsandbrass
eyelets to isolate them from vibration. Do not over-
tighten the mounting screws; this will negate the

securely, it provides the proper security as well as the 
proper vibration isolation for your servo.
2. Theservosmustbeabletomovefreelyovertheir
entire range of travel. Make sure that the control 
linkages do not bind or impede the movement of any 
of the servos.
3.  Mount all switches away from the engine exhaust and 
away from any high-vibration areas. Make sure the 
switch operates freely and is able to operate over its 
full travel.
It’s necessary to program the receiver to the transmitter 
so that the receiver will only recognize that specific 
transmitter, ignoring signals from any other sources. If the 
receiver is not bound to the transmitter, the system will 
not operate. During binding, the servo’s fail-safe positions 
are stored.

power lead from the switch into the receivers bind 
port. If a 3-wire switch is not available, install the male 
bind plug into the bind plug receptacle and power the 
receiver through any other open port to enter bind 
mode.

to the correct model memory and you’re set to fly.
