It is extremely important that your radio system be
correctly installed in your model. Here are a few
suggestions for installing your JR® equipment:
1. Wrap the receiver in protective foam rubber that is
no less than 3/8 inch thick. Secure the foam to the
receiver with #64 rubber bands. This protects the
receiver in the event of a crash or a very hard landing.
2. The servos should be mounted 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.
3. 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.
4. 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.
5. Mount the receiver antenna firmly to the airplane
to ensure that it will not become entangled in the
propeller or control surfaces.
All preprogrammed data is protected by a flash memory
that guards against main transmitter battery failure.

Helicopter with typical plug order, switch location,
and battery pack connections.
When the transmitter voltage drops below 9.0 volts DC,
the display flashes “BATT LOW” and an alarm sounds.
If you are flying when this occurs, land immediately.
