CONNECTION OF RECEIVER, SERVOS, ETC.
FIG.9
(Installation precautions)
When installing the receiver, servos, and other parts to the fu-
selage, observe the following precautions:
Servo travel
Operate each servo horn over its full travel and check that the
pushrod does not bind and or is not too loose. Unreasonable
force applied to the servo horn will adversely affect the servo
and drain the battery pack very quickly. Make sure that the
free travel range of each control surface or mechanism
somewhat larger than the full control travel (including trim) of
the servo horn. Adjust the servo horns so that they move
smoothly even when the trim lever and stick are operated si-
multaneously in the same direction.
Servo installation
Install the servos with the rubber
grommets and eyelets supplied with
the set. (FIG.8) Do not tighten the
screws too tight. If the servo case di-
rectly contacts the fuselage, the rub-
ber bushing will not serve its pur-pose.
Receiver power switch installation
When installing the switch harness to the fuselage, cut a rect-
angular hole slightly larger than the full travel of the switch in
the fuselage and install the switch so that it moves smoothly
from ON to OFF. Also install the switch where it will not be
exposed to engine oil or dust and dirt. Generally, install the
receiver switch on the opposite side of the muffler exhaust.
Receiver antenna
Although the receiver
antenna may appear to
be too long, do not cut it
or fold it back. Chang-
ing the length of the re-
ceiver antenna will
lower the receiving sen-
sitivity and shorten the
flight range. Generally,
"Install the antenna by stretching
it slightly with a rubber band, etc.
the antenna can be strung out towards and attached to the
vertical stabilizer. (FIG.9)
Receiver vibration and water proofing
The receiver contains precision electronic parts. Besides be-
ing susceptible to vibration and shock, the entry of water will
also cause erroneous and dangerous results and has been
associated with crashes and other accidents. Wrap the re-
ceiver in foam rubber or take other vibration countermea-
sures. Also waterproof the receiver by placing it in a plastic
"Use a rubber bushing so that the antenna
will not be broken by abrasion where it
comes through the fuselage and always
knot it inside the fuselage so that it will
not come out.

bag and securing the open end of the bag with a rubber band.
Do the same with the receiver and servo battery.
Servo horns
Spare horns are supplied. Use them as needed.
Extension cord
Use the servo extension cord if needed for your particular
fuselage.
Digital Proportional Frequencies For U.S.A.
• The frequency of Futaba digital proportional sets can be
changed within their own band. There are 2 different bands
for you to choose from (27 MHz and 72-75 MHz). Please see
chart listed below for specific frequency and its intended use.
Please note there are specific frequencies allocated for air-
craft only and surface only use.
• The frequency can be changed within the same BAND. How-
ever, Futaba recommends that you return your system to our
factory service department for frequency changing, as tuning
may be necessary for proper operation. Changing frequency
from one band to another is NOT possible.
Always change frequency flag when frequency is changed.
The frequency flag is to be attached to the top of antenna and
the channel designation to the base. (See Drawing)
• It is illegal to change crystals on 72-75 MHz bands in the
U.S.A. unless performed by a licensed technician.
Antenna Frequency Flag
The flag can be attached to.
and removed from. the
antenna with one touch.
Attach the frequency flag to the flag
holder as shown in the figure.
1 Slick the channel No. sticker
on the flag board.
2 Attach the flag board to the
antenna as shown in the
