TRANSMITTER FP-T2GS
•Contemporary styling with smoothoperating gimbals for
superior control.
•500mW output.
•Battery level meter indicatesthestate of the battery
voltage at a glance.
•Built-in antenna.
RECEIVERFP-R102GF
•BEC(BatteryEliminatorCircuitry)system allowssharing
of the running Nicd battery and eliminates the need for a
regulator and diode.
•High performance 2 channel receiver with ASP system
when used with the proper transmitter.
•Crystal socket uses a new type of highly reliable subminia-
ture pins. Reliabilityis increased and the crystalcan be
changedfrom the outside.
SERVO FP-S128
SMALL, RUGGED. HIGH NEUTRAL SERVO
•Skew type armature motor.
Movement of the trimmer byeven one notch istracked by
askew type motor which displaysa performance near that
ofa coreless motor.
•New indirect drivepotentiometer improves vibration and
shockresistanceandneutralaccuracy.
•Futaba low-power custom 1Cprovides extremelyhigh
torque, narrow dead band, and superior tracking.
•FiberglassreinforcedPBT (polybutylene terephthalate)
injection molded servo case is mechanically strong and
invulnerable to glow fuel.
•Strong polyacetal resin ultra-precision servo gear features
smooth operation, positive neutral, and verylittle backlash.
•Fiberglass reinforcedepoxy resin PCboard withthru-the-
hole plating improves servo amp vibrationand shock resist-
ance.
•Three pin connector eliminates faulty contact and improves
reliabilityagainst vibrationand shock. Housing has a
reverseinsertionpreventionmechanism.
•Special grommet simplifies mounting of the servo andhas
an excellentcushioning effect.
•Six special adjustablesplined horns.
•High 48.7 oz.in (3.5kg-cm) maximum outputtorqueallows
use inalmost any model.

HANDLINGTHETRANSMITTER
•The name of each part of the transmitter is given inthefigure.
Familiarizeyourselfwith their operation.
•Remove the battery cover on the rear of thetransmitteras
illustrated inthe figure, and insert8 round penlight batteries,
paying carefulattention to their polarity.
•Extend the antenna fully,and set the power switch tothe
ON position. The pointer of the level meter should deflectto
the green zone. Ifit failsto deflect,or deflectsslowly,the
polarityof the batteries is incorrect, or the batteriesare
faulty.
•Since the range of the radio waves will become short when
the pointer of the level meter deflectsto the red zone, re-
place the batterieswhen 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 correctthe flyingposture after
themechanism has been installed. Aftertest flight,operate
with the trim lever inthe neutral position, as faras possible,
by correctingwiththe rod adjuster,etc.
•Since the elevatorstickemploys a self-neutralsystem, install
the sliding plate as shown inthe figurewhen changing it to a
ratchet system.Then remove the strongspring attached to
the hook and replace itwith the springsupplied asan ac-
cessory.
•When thetransmitter isusedwith a tank, the direction of the
stickcan bechanged 90degrees by removing the four rudder
stickmounting screws.
•To change the crystals,loosen the rearcovermounting screws,
remove the rear cover,and then replacethe crystal.The
crystalis located atthe leftside of the printedwiringboard.
The transmittercrystalismarked (T)and the receivercrystal
is marked (R).CAUTION:Frequency change has to be done
underthe supervision of FCC licensed personnel.

Operate thetransmittersticksand check ifeach servo faithfully
followsoperationofthe sticks.
•Connectthepushrodtoeach servo horn, then check if the direc-
tionof travelof each servomatchesthetransmitteroperation.
•Operateeach servoover its fulltraveland checkifthepushrod
binds or is too loose. Applyingunreasonableforceto theservo

Beespeciallycarefulwhen using8.4V.
•Alwaysmake thefullstroke(includingtrim) of the servo horns
somewhat larger than the fulltravel.Adjusttheservohornsso
thattheymove smoothly even when thetrimleverand stickare
operatedsimultaneouslyinthe same direction.
•Bealertfornoise.

commend the use ofnoiselessparts.
•Even though thereceiverantennawireis long, do not cut or
bundleit. The range ofthe radiowaves willbeshortened.
•A spare horn isprovided. Useitas required.
•Wrapthereceiverinsponge rubber and wrap rubber bands around

•Whenthereceiveris installedon a board or used where itmay be
splashed withmud and water,placeitina plasticbag, etc.and
wrap a rubber band aroundtheopen end of thebag towaterproof
and dustproofthe receiver.Afteruse,remove the receiver from
thebag topreventcondensation.
•Use the rubber bands wrapped aroundthe receiver to hold the
servo and switchleads.
•Aftermountingis complete,recheckeach part,then checkthe
transmittingrange bymakingthetransmitterantennaas shortas
possibleand extendingthereceiverantennafullyand operating
theset froma distanceof20m to30m. The movement ofeach
servoshould followthemovementofthetransmittersticks.

~(6)on the27MHzband only.
•However,a 27MHzband set cannotbe
changed to 72MHzband, and viceversa.
•Therefore,alwaysattachthe correctfre-
quencyflagto the end ofthe transmitter
antenna.Eachfrequencyband has itsown
designated color, as stated in the left. The
frequency flagisintended for identifica-

2) Theminimum adjustable angleis
determined bythe number of arms or
