Installation Requirements
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 from shock in the event of a crash or a very
hard landing.
2. Mount the receiver antenna firmly to the airplane
to ensure that it will not become entangled in the
propeller or control surfaces.
3. The servos should be mounted using rubber grommets
and brass bushings to isolate them from vibration. Do
not over-tighten the mounting screws; this will negate
the vibration absorption effect of the rubber grommets.
The diagram below will assist you in properly mounting
your servo. The brass bushings 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.
4. 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.
5. Mount all switches away from the engine exhaust and
away from any high vibration areas. Make sure each
switch operates freely and is able to operate over its
full travel.
trim lever for an extended time will cause the trim rate of change to increase.
