SPECIAL FEATURES:
TRANSMITTER FP-T2GS
• Contemporary
superior control.
• 500mW output.
• Battery level
voltage at a glance.
• Built-in antenna.
RECEIVER FP-R102GF
•BEC (Battery Eliminator Circuitry) system allows sharing
of the running Nicd battery and eliminates the need
regulator and diode.
•High performance 2 channel receiver with ASP system
when used with the proper transmitter.
•Crystal
socket
ture pins. Reliability is increased and the crystal can be
changed from the outside.
SERVO FP-S128
SMALL, RUGGED. HIGH NEUTRAL SERVO
•Skew type armature motor.
Movement of the trimmer by even one notch is tracked by
a skew type motor which displays a performance near that
of a
coreless motor.
•New indirect drive potentiometer improves vibration and
shock resistance and neutral accuracy.
•Futaba low-power custom 1C provides extremely high
torque, narrow dead band, and superior tracking.
•Fiberglass reinforced PBT (polybutylene terephthalate)
injection
invulnerable to glow fuel.
•Strong
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 resistance.
•Three pin connector eliminates faulty contact and improves
reliability against vibration and shock. Housing has a
reverse insertion prevention mechanism.
•Special grommet simplifies
an excellent cushioning effect.
•Six special adjustable splined horns.
•High 48.7 oz.in

HANDLING THE TRANSMITTER
•The name of each part of the transmitter is given in the figure.
Familiarize yourself with their operation.
•Remove the battery cover on the rear of the transmitter as
illustrated in the figure, and insert 8 round penlight batteries,
paying careful attention to their polarity.
•Extend the antenna fully, and set the power switch to the
ON position. The pointer of the level meter should deflect to
the green zone. If it fails to deflect, or deflects slowly, the
polarity of the batteries is incorrect, or the batteries are
faulty.
•Since the range of the radio waves will become short when
the pointer of the level meter deflects to the red zone, replace the batteries when the pointer only deflects to the
boundary between the green and red zones.
•The
trim
lever
is
used
to fine
adjust
each
channel.
Use
it for
neutral adjustment and to correct the flying posture after
the mechanism has been installed. After test flight, operate
with the trim lever in the neutral position, as far as possible,
by correcting with the rod adjuster, etc.
•Since the elevator stick employs a self-neutral system, install
the sliding plate as shown in the figure when changing it to a
ratchet system. Then remove the strong spring attached to
the hook and replace it with the spring supplied as an accessory.

•When the transmitter is used with a tank, the direction of the
stick can be changed 90 degrees by removing the four rudder
stick mounting screws.
•To change the crystals, loosen the rear cover mounting screws,
remove the rear cover, and then replace the crystal. The
crystal is located at the left side of the printed wiring board.
The transmitter crystal is marked (T) and the receiver crystal
is marked (R). CAUTION: Frequency change has to be done
under the supervision of FCC licensed personnel.

The Futaba BEC (Battery Eliminator Circuitry) system and BEC
& ASP (Adjustable Safety Position) system can also use a common power supply with the conventional four penlight batteries
system (separate power supply).
