è Install the servos firmly. Install the servo to the servo tray
as shown in the figure. In other cases, install the servo as
described in the model manufacturer’s manual.
è A spare horn is provided. Use it as required.
è Wrap the receiver in sponge rubber and wrap rubber bands around the
sponge rubber. Mount the receiver so it is not exposed to vibration, does
not touch the frame, and does not move.
@ When the receiver is installed on a board or used where it may be splashed
with mud and water, place it in a plastic bag, etc. and wrap a rubber band
around the open end of the bag to waterproof and dustproof the reciever.
After use, remove the receiver from the bag to prevent condensation.
e Use the rubber bands wrapped around the receiver to hold the servo and
switch leads.
e After mounting is complete, recheck each part, then check the transmitting
range by making the transmitter antenna as short as possible and extending
the receiver antenna fully and operating the set from a distance of 20m to
30m. The movement of each servo should follow the movement of the
transmitter sticks.
è The crystal can be changed from the outside of the receiver case. Always
use a Futaba transmitter and receiver crystal pair as the replacement crys-
tals.
MOTOR CAR
Operation of the throttle (engine control) servo can be set as
shown in this figure by (2) throttle trigger operation.

USING THE ANTENNA FREQUENCY FLAG
@SPLINED HORNS
This horn permits shifting of the
servo neutral position at the servo
horn. Setting and shifting the
neutral position
a) Angle divisions
Fig. 16
1) The splined horn has 25 seg-
ments. The amount of change per
segment is; 360+25=14.4°
2) The minimum adjustable angle
is determined by the number of
arms or number of the holes. For
four arms, the minimum adjustable
angle is:
(25 x 4) o
o. Z
360 + Number of divisions R
b) Effect
~ Baseline A
Insert the frequency
flag into the flag
as shown
The flag can be attached
to and removed from the
end of the antenna with
one touch.
Staple or glue with cyano-
acrylate ribbon here.
Fig. 15
To shift the holes center line to
the right (clockwise) relative to
baseline A, shift arm 2 to the po-
sition of arm 1 and set it to the
position closest to baseline A.
[Example] For a four arm horn,
the angular shift per segment is
14.4°. The shift to the right is 90°
— (14.4 x 6) = 3.6°
To shift by the same angle in the
opposite direction, use the oppo-
site arm number.
Fig. 18
For a six arm horn, turn the arm
counterclockwise and set arm 2
to the position of arm 1. The ad-
justable angle is 60° — (14.4 x 4)
=2.4°.
Arm 3 shift 4.8° to the right, arm
6 shifts 2.4° to the left,and arm 4
shifts 7.2° to the right and left.
