Thank you for purchasing a Futaba digital proportional radio control set.
Please read this manual carefully before using your set.
FEATURES OFFP-4NBL
The FP-4NBL is a 4 channel AM proportional radio control
set with an ergonomic case created as a result of the exhaustive
pursuit of easier operation, newly designed sticks for smooth
and positive operation, servo reversing switch for each chan-
nel, and other innovations based on the opinions and needs of
many RC modelers.
Please read this manual before using your new set.
TRANSMITTER FP-T4NBL______________
•Servo reversingswitch foreach channel.Servos are reversed
byusing thisswitch.
•Newly designed sticks operate smoothlyandpositively.
Spring tension mechanismallowsadjustment of the operat-
ingfeelof the sticklever.
•Nonslip adjustablelever headallows adjustment of the stick
lengthasdesired.
•Functionalcase, createdas a result of theexhaustivepursuit
of easieroperation,hasevolved a thick case which fitsinto
the palm of the hand.
•Easy to read transmitterbattery voltage/output level meter.
•Neck strapbracket providedas standard. Operationiseasier
ifthe transmitteris hungfromyour neck byusing the neck
strap.
•Nicad operation as standard.
RECEIVERFP-R114H
•HighperformanceAM 4 channel receiver inwhich miniature
sizeand light weighthavebeen achievedby using thePC
board spaceto the maximum.
•Narrowband ceramicfilterimproves rejection of adjacent
channel interference.
FEATURES OF MCR-4A RECEIVER
•Narrow band design using a narrow bandceramic filter.
FEATURESOF MCR-4A AMP
•Built-inheat protectorpreventsoverheating ofthe amplifier
bya continuous overcurrent.
•Motor idle or maximum slow can bearbitrarilyset atthe
transmitterthrottlestick maximum slow position by built-in
idle point trimmer.
SERVO FP-S148 RUGGED, LOW-PROFILESERVO
•Vibration andshock resistance have been improved further
byusing a directwiringsystemwhich directlyconnects the
servoamp, motor and potentiometer.
• The height of the servo has been reducedand high torque,
high speed, and smooth movement equal to thatof the core-
less servo have been realizedbyusing a new small, high-
performancemotor. (Output torque 3kg.cm,operating
speed 0.22 sec/60°).
SERVO FP-S133HIGH-QUALITY MICROSERVO_
•Futaba hybridcustom 1Cprovideshigh startingoutput
torque, narrowdead-band, and excellenttrackability.
•Thick filmgoldplatedconnector pinsinsurepositivecontact

tion.The connector housing has a reverse insertion preven-
tionmechanism.
•Adjustable(splined)horn permits arbitrarysetting ofthe
neutral position.
•Despite being a microservo, operating speed is a fast 0.21
sec/ 60°and output torque isa high2.2 kg/cm.

troublesome wiring isunnecessary and the model can be
made lighter.

Fig. 8
The idle point trimmer sets the drive motor idling point.
•Set the transmitterthrottle
servoreversingswitchto the
normal position.
•Setthe transmit throttle
stickto the slowest position
(stickallthe way back ),
turn on the MCR-4Apower
switch, pressthe startswitch,
and setthe idle point trim-
mer to the pointatwhich
the motor idles.
•Ifthe startswitch is not
pressed, the drive motor will
not run.
•Turn the idlepointtrimmerslowly andwithouttoomuch
force.
•Ifthe drivemotor rotates inthe reverse direction, change
the connection ofthe lead wirefromthe MCR-4Aat the
motor terminals.
•Before pressing the MCR-4A start switch, check that the
transmitterthrottlestickis in the slowestposition. Starting
the drivemotor suddenly is dangerous. This also applies
when the idle point trimmeris changed. Be verycareful.
•Ifan overcurrentflowscontinuously in the motor forsome
reason, the heat protector willoperateand stop the motor.
When the temperaturedrops aftera short time, the motor
can becontrolledonce more.
Correct the cause of the continuous overcurrent before using
the set.
•The heat protectordoes not protect the set againstmomen-
taryovercurrentcaused byshorting of the drive motor lead
wires,etc.
•Ifthe drivemotor is stopped bythe "autocut" function dur-
ing flight, land the aircraftimmediately and safely.

PRECAUTIONS
•Connect the receiver(orMCR-4A),servos, switches, and
battery firmlyas shown inFig. 7 (Fig. 8). Then extend the
transmitterand receiver antennas fully.
•Setthe transmitterpower switch toON. Then setthe receiv-
er(orMCR-4A)power switchtoON. The servosstop near
the neutralposition.Operate the transmittersticksand
check that each servofollowsthe movement of the stick.
•Connect the pushrod to each servohorn,then check if the
directionof travelof each servomatchesthe direction of
operationof its transmitterstick.To reversethe direction of
servotravel,switchthe servoreversingswitch.
•Operate each servooveritsfulltravel,and check if the push-
rod binds or is too loose. Applyingunreasonableforceto the
servohorn willadverselyaffectthe servoand quickly drain
the battery.Alwaysmake the travelof each control mecha-
nism somewhat larger than the fulltravel(includingtrim)of
the servohorn. Adjust the servohorns sothat they move
smoothly even when the trimleverand stickare operated
simultaneouslyinthe same direction.
•Bealertfornoise.
This set is noise-resistant,butis not completely immune to
noise. We recommend the use of noiseless parts and noise
killercapacitor.
•When installingthe switch harness, cut a rectangular hole
somewhat largerthanthe fullstrokeof the switchand install
the switchso thatit moves smoothly fromON to OFF. This
also appliesto the switchmount when the switch is install-
ed inside the fuselage and is turnedon and offfromthe out-
side with a piece of wire,etc. Install the switchwhere it will
not beexposedto engine oil,dust,etc.
•Eventhough the receiverantennais long, donotcutor
bundle it.
•Installthe servos securely.Tighten the mounting screws un-
til the rubber grommet iscrushedslightly.If the screwsare
too tight, the cushioning effectwill beadversely affected.
SERVO MOUNTING
Fig. 10
•Spare servo horns are supplied. Use them as needed.
•Wrapthe receiverinsponge rubber. Waterproofand dust-
proof the receiverbyplacing itin a plasticbag and wrapping
arubber band around the open end of the bag.Dothe same
withthe receiver/servobattery.
•Use therubber bands wrappedaround the receiver to hold
the servoand switchleads.
•Aftermounting iscomplete,recheck eachpart, then check
the range bymaking the transmitterantenna as short as
possible, extendingthe receiverantenna fully,and operating
the set froma distanceof20m to 30m. The movement of
each servoshould followthe movement of each stickof the
transmitter.
•The motor controller connects to channel 3 inthe MCR-4A.
• Motor aircraftvibrate less thanengine aircraft,butthe
receiver and servoshould bevibrationproofed.
•Ifthe NiCdbattery pack is connected inreverse,
the MCR-4Amay bedamaged beyond repair.Be
surethatthe (+)and (—)connectionsarecorrect.

•Aftermounting and checking are complete, takeyour model
to the shop where you purchased the set, or to an experienc-
ed radio controlmodeler, and ask them to teach youhow to
handle your radiocontrolsetinthe proper manner and to
inspect your set-up carefully.
• To enjoyradio control models fully, be sure to observe all
safety standards.
