Thank you for purchasing a Futaba digital proportional radio control set.
Please read this manual carefully before using your set.
FEATURES OF FP-6NLK/5NLK
The FP-6NLK and FP-5NLK are 6 channel (6NLK) and 5
channel (5NLK) FM proportional radio control set with a
ergonomic case created as a result of the exhaustive pursuit
of easier operation, newly designed sticks tor smooth and
positive operation, servo reversing switch for each channel,
and other innovations based on the opinions and needs of
many RC modelers.
Please read this manual before using your new set.
TRANSMITTERFP-T6NLK/T5NLK
•Reliabilitysubstantiallyimproved byusing industrial robots
to assemblethePC board.
•Servoreversingswitchforeach channel. Servosare reversed
by using thisswitch.
•Newly designed open gimbal sticksoperate smoothly and
positively.
Springtensionmechanism allowsadjustment of the operat-
ing feelof the sticklever.
•Nonslip adjustable lever head allows adjustment of the stick
lengthasdesired.
•RFPC board module stylesystem intransmitter. (Internal
only)
•Functional case, created as a result of the exhaustivepursuit
of easier operation, has evolved a thick case which fits into
thepalm ofthehand.
•Aileron,Elevatordual ratefunction. (Dualrate ON, OFF)
•Easy to read square transmitterbatteryvoltage/output level
meter.
•Excellentradiationefficiency,strong8-stage telescoping
antenna.
•Neck strapbracketprovided as standard. Operation is easier
ifthe transmitteris hung fromyour neck byusing the
optional neck strap.
•Large capacitor copes with voltage changes when a battery is
used.
•Vibration-resistantpinconnectors.
•Fiberglass epoxy PCboard with thru-the-hole plating is vi-
bration and shock resistant.
SERVOFP-S138
SMALL, RUGGED, HIGH NEUTRAL LOW PROFILE SERVO
•Height is 0.2 in(5.2mm) lower than existingservosof its
type.
•New indirectdrivepotentiometerimproves vibration and
shock resistanceand neutralaccuracy.
•Futaba low-power custom1Cprovidesextremelyhigh
torque,narrowdead band, and superiortracking.
•FiberglassreinforcedPBT (polybutyleneterephthalate)

invulnerabletoglowfuel.
•Strongpolyacetalresin ultra-precisionservogear features
smoothoperation,positiveneutral,andverylittlebacklash.
•FiberglassreinforcedepoxyresinPC board withthru-the-
hole plating improves servoamp vibrationand shock resist-
ance.
•Threepin connector eliminatesfaultycontact and improves
reliabilityagainstvibrationand shock.Housing has a reverse
insertionpreventionmechanism.
•Specialgrommetsimplifiesmounting of the servo and has
an excellentcushioningeffect.
•Sixspecialadjustablesplined horns.
•Since the output torqueis34.75oz-in(2.5kg.cm)and operat-
ing speed is 0.23sec/6CT, itcan be used withalmost all
models.
RECEIVERFP-R107N
•Compact, high performance FM 7-channel receiver with PC
board space reduced toa minimum.
•SpecialIF amp forradiocommunications improves the
effectivereceivingrange stability.
•Narrowband ceramicfilterimproves rejection of adjacent
channelinterference.
•Futaba originalsquelch circuit reduces erroneous operation
by weak signals (when passing a dead point, etc.) and er-
roneous operation by naturalnoise when nosignalsare being
received.

PRECAUTIONS
• Connect the receiver, servos, switches, and battery firmly as
shown inFig. 9.Then extend the transmitter and receiver
antennasfully.
•Set the transmitterpower switch to ON. Then set the receiv-
er power switchto ON. The servosstop near the neutral
position.Operate thetransmittersticksand check that each
servofollowsthemovementofthestick.
•Connectthe pushrod to each servohorn, then check if the
directionof travelof each servomatches the direction of
operationof its transmitter stick. To reverse the direction
ofservotravel,switchtheservoreversingswitch.
•Operateeach servooveritsfullstroke,and check if thepush-
rod binds or istooloose.Applyingunreasonableforceto the
servohorn willadverselyaffecttheservoand quicklydrain
the battery.Alwaysmakethetravelofeachcontrolmecha-
nism somewhatlargerthan thefulltravel(includingtrim)of
the servo horn. Adjust the servo horns so that they move
smoothlyevenwhen the trimleverand stick are operated
simultaneouslyinthesame direction.
•Be alertfornoise.
Thissetis noise-resistant,butis not completely immune to
noise.Werecommend theuse of noiselessparts.
•When installingthe switch harness, cut a rectangular hole
somewhatlargerthanthefullstrokeof theswitchand install
the switchso thatitmovessmoothlyfromON to OFF.This
alsoappliesto the switch mount when the switch is installed
inside thefuselageand is turnedon and offfromtheoutside
witha pieceof wire,etc.Installtheswitchwhereit willnot
beexposedtoengine oil,dust, etc.

SERVOMOUNTING
(Using wood screws)

•Even though the receiver antenna islong,donotcut or
bundle it.
•Installthe servossecurely. Tighten the mounting screws
until the rubber grommet iscrushed slightly.If the screws
are too tight, the cushioning effectwillbeadversely affect-
ed.
•Wrapthereceiverinsponge rubber. Waterproofand dust-
proof thereceiverby placingitina plasticbag and wrapping
arubber band around the open end of thebag. Do the same
withthereceiver/servobattery..
•Use therubber bands wrappedaround the receiver to hold
the servoand switchleads.
•Aftermounting iscomplete,recheck each part, then check
the range by makingthetransmitterantennaas short as
possible,extendingthereceiverantennafully,and operating
the set froma distanceof 20m to 30m. The movement of
each servo should follow the movement of each stick of the
transmitter.
•Aftermounting and checking are complete, take your model
to the shopwhereyoupurchasedtheset,or to an experienc-
ed radiocontrolmodeler,and ask them to teachyouhow to
handle your radio control set inthe proper manner and to
inspect your set-upcarefully.
•Toenjoyradiocontrolmodels fully,besure to observe all
safetystandards.
AILERONAND ELEVATOR DUAL (dual rate ON,
OFF) ADJUSTMENT
When the dual switchisset to ON, theservothrowismade
smallerby the amount shown by thehatched linesinFig.10.
The servothrowcan be setfrom40% to100% ofthe total
travelby adjustingthetrimmernexttotheswitchwitha flat
bladed screwdriver.WhenthedualrateswitchissettoOFF,
the throw is normal. When desiring a larger throw, such as for
spins, etc.,set the dual rateswitchtoOFFand adjustthe
throwmechanicallyby horn and rod adjustment.Set the
dual rate switch toon for level flightand adjust the trimmer
forthe requiredamountofthrow.
When the dual rateswitch is set to OFF,dual rateis set and
the throw becomes large.
