Position the crystal side at the top instead of the bottom side. Please refer
to the following diagrams.
Space available in your model will determine how much padding can be
placed around the receiver. When the receiver in a good quality foam rubber,
such as those available from Du-Bro, Carl Goldberg, Sig, and others. R/C
foam is made from natural rubber, which eliminates vibration far better than
synthetic foam, (such as the kind used for packing many consumer times).
CAUTION
The receiver contains precision electronic parts. These parts are
vulnerable to vibration and shock.
NOTE
When wrapping the receiver, keep in mind that you are trying to cushion
a delicate piece of electronic equipment, so "wrap" the foam, don't
"stretch" it around the receiver.
HELPFUL HINT
It is quite a simple way to isolate the receiver from vibration by attaching
to the chassis or mounting plate with thick double-sided tape.

Many modelers prefer to install their receiver into the model at this point,
with no further protection. Another sizeable group of modelers prefer to go
a step further, and place the foam-wrapped receiver into a plastic bag,
secured with a rubber band around the receiver case as well as the servo
and battery wires.
The advantage of the plastic wrap is the protection against fuel or oil in the
event of a major crash. The disadvantage of the plastic, especially if you
run the model in very hot and humid conditions or wet days, is that moisture
can accumulate inside the receiver.
CAUTION
Any contact with moisture i.e. water or condensation may cause
malfunction and loss of control.
HELPFUL HINT
If you choose to wrap your receiver in both foam and a plastic bag, it
is recommended to periodically remove the receiver from your model,
remove the foam and bag to let the receiver "air out". This maintenance
procedure will let you determine if any moisture is accumulating in the
protective wrap. Small holes cut into the bag will allow airflow into the
receiver, and eliminate the need for the periodic checks, although you
will lose a certain amount of protection against fuel or oil with this step.
Battery installation
Always wrap the battery pack in foam, and mount it in the location specified
in your models instructions. It is also recommended to wrap the battery pack
in a plastic bag, as its location (close to engine and fuel tank) makes fuel
proofing vital.
Switch installation
Pick the most convenient location for your on/off switch as required by your
particular model. Always mount the switch on the opposite side of the engine
exhaust. After mounting the switch, carefully bundle any excess servo wires
with cable ties, keeping them away from any moving item (pushrod, servo
arm, etc.) that could catch and cut the wires. Any empty space in your
fuselage radio compartment can be filled with excess foam.
