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. Mounttheservosusingrubbergrommetsandbrass
eyelets to isolate them from vibration. Do not over-
tighten the mounting screws; this will negate the
vibrationabsorptioneffectoftherubbergrommets.The
following diagram will assist you in properly mounting
your servo.
 Thebrasseyeletsarepushedfromthebottomupinthe
rubbergrommets.Whentheservoscrewistightened
securely, it provides the proper security as well as the
proper vibration isolation for your servo.
2. Theservosmustbeabletomovefreelyovertheir
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.

How To Bind

bind mode through the switch. Plug the receiver’s
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.
