uirements
 
It is extremely impor
tant that your radio system be correctly 
installed in your model. Here are a few suggestions on the 
installation of your JR equipment.
 
 
1.
 
W
rap the receiver in protective foam rubber that is no les
than 3/8 inch thick. Secure the foam to the receiver with #6
rubber bands. This protects the receiver in the event of a cras
or a ver
y hard landing.
 
 
 
 
 
 
 
Servo Mounting Tab
 
 
Screw
 
 
Rubber Grommet
 
 
Brass Bushing
 
2.
 
The ser
vos 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 
ef
fect of the rubber grommets. The diagram at left will assist you 
in properly mounting your ser
vo.
 
 
The brass bushings are pushed from the bottom up in the rubber 
grommets.  When the ser
vo screw is tightened securely
, it 
provides the proper security
, as well as the proper vibration 
isolation, for your ser
vo.
 
 
3.
 
The ser
vos 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 ser
vos.
 
 
4.
 
Mount all switches away from the engine exhaust and awa
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 fir
mly to the airplane to ensure 
that it will not become entangled in the propeller or control 
sur
faces.
