The receiver should be loosely mounted in foam rubber or foam pl-
astic to protect against vibration and shock. Battery pack should also
be protected from vibration by wrapping in foam rubber. The receiver
should also be protected from fuel by wrapping it in a plastic bag.
The
receiver
antenna
must be kept
as
far
as
possible
from
other wiring
and metal parts. Excessive electrical noise is generated by metal to
metal connections and may seriously interfere with receiver reception.
Such metal to metal contacts, such as throttle linkage, should be made
with nylon devices This receiver has one of the most noise resistive
circuits on the market but care should be taken to keep electrical no-
ise at a minimum.
PRE-FLIGHT CHECK:
The final check of the system should be performed with the engine
running at a distance of 20—30 yards with transmitter antenna ret-
racted. If the distance is substantially less than with engine not runn-
ing, you can be sure something in your installation is causing inter-
ference from excessive vibration.
When all the above test are concluded satisfactorily you are ready
for your first flight. If you have no previous experience with propro-
tional equipment, an experienced flyer should be enlisted to perform
the initial flying and trimming of the craft.
