FEATURES OF MAGNUM SPORT
The Magnum series are pistol grip type of AM 2 channel digital
proportional radio control sets.
TRANSMITTER FP-T2P
@ Human-engineered size and design are easy to use.
@ Wheel angle adjuster. The turning angle of the steering wheel
can be increased and decreased. This allows operation at the
best angle.
© Neutral adjuster. The throttle trigger throttle stroke/brake
deflection stroke (back stroke) can be freely selected to
match the application.
@ Servo reversing switch (steering and throttle) is standard.
Each servo can be reversed from the outside. This is extreme-
ly convenient when connecting the linkages.
@ Since a level meter is provided, battery consumption can be
seen at a glance.
@ Crystals can be changed from the outside on 27MHz only as
itis illegal to do this on 72MHz and 75MHz in U.S.A.
RECEIVER FP-R102GR
e BEC (Battery Eliminator Circuitry) system allows sharing of
the running Nicd battery and eliminates the need for a
regulator and diode.
e Crystal socket uses a new type of highly reliable subminia-
ture pins. Reliability is increased and the crystal can be
changed from the outside.
SERVO FP-S148, S129
@ Motor uses the newest helical type rotor for improved out-
put torque and smooth operation. (S129)
@ These heavy-duty & water/dust tight servos are designed for
use with Futaba digital proportional radio control sets. (S129)
@ New indirect driver potentiometer improves vibration and
shock resistance and increases neutral precision tremendous-
ly.
@ Futaba low-power custom IC provides high starting torque,
narrow dead band, and excellent trackability.
© Fiberglass-reinforced PBT (polybutylene terephthalate) in-
jection molded servo case is mechanically strong and in-
vulnerable against glow fuel.
© Strong polyacetal resin ultra-precision servo gear features
smooth operation, positive neutral, and very little backlash.
@ Fiberglass-reinforced epoxy resin PC board with thru-the-
hole plating improves servo amp vibration and shock resist-
ance.
@ Thick film gold-plated connector pins eliminate poor contact
and improve reliability against shock and vibration.
@ Special grommet bushing simplifies servo mounting and
improves the cushioning effect.
© Six special adjustable splined horns are available.
@ Maximum output torque of 48.7 0z-in.(3.0kg-cm/3.5kg-cm)
allows
use
in
almost
any
model.

switch is turned on, the level pointer should deflect to within
the silver zone. If the pointer does not deflect, or deflects very
little, check for poor battery contact, incorrect battery polarity,

(@ Transmitter crystal
When changing the frequency, replace this crystal. Use the
AM crystal set (transmit and receive 1 pair) sold by Futaba.
The transmitter crystal is marked TX and the receiver
crystal is marked RX. However, you are not allowed to
change frequency by merely replacing crystal on both 72
and 75MHz.

Since they cause a voltage drop, always remove them.
e Set the transmitter power switch to ON, then set the receiver power
switch to ON. The servos stop near the neutral position. Operate the
transmitter sticks and check if each servo faithfully follows operation
of the sticks.
e Connect the pushrod to each servo horn, then check if the direction
of travel of each servo matches the transmitter operation.
è Operate each servo over its full travel and check if the pushrod binds
or is too loose. Applying unreasonable force to the servo horn will
adversely affect the servo and quickly drain the battery. Be especially
careful when using 8.4V. .
e Always make the full stroke (including trim) of the servo horns some-
what larger than the full travel. Adjust the servo horns so that they
move smoothly even when the trim lever and stick are operated simul-
taneously in the same. direction.
e Be alert for noise.
Always solder a noise killing capacitor to the running motor. If metal
parts touch each other due to vibration, noise will be generated and
cause the receiver servos to operate erroneously. We recommend the
use of noiseless parts.
e Even though the receiver antenna wire is long, do not cut or bundle it.
The range of the radiowaves.will be shortened.

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.

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

~ 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.
