5.10 Installation Requirements
It is extremely important that your radio system be correctly
installed in your model. Here are a few suggestions on the
installation of 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 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 at left 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.
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 each 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.
