Thank you for purchasing a Futaba digital proportional radio control set.
Please read this manual carefully before using your set.
FEATURES OF FP-6NLK/4NL
TheCONOUESTFP-6NLKand FP-4NL are 6 channel (6NLK)
and 4 channel (4NL) AM proportional radio control set with
aergonomic 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 channel,
and other innovations based on the opinions and needs of
many RC modelers.
Please read this manual before using your new set.
TRANSMITTER FP-T6NLK/T4NL
•Reliabilitysubstantiallyimproved byusing industrial robots
toassemble the PC board.

plug the FBC-8B to a 117VACoutlet as shown inthis figure.
•TheReceiverbattery canbeused about 10times at 10
minutes perflight between rechargings.
•Charge the batteries for about 15hours. When the set is not
inuse forsome time, repeat dischargeand charge twoto
three times before use. (Ifthe batteries are notused for a
long time, theircapacitywillgo down).

PRECAUTIONS
•Connect the receiver,servos,switches, and batteryfirmlyas
shown inFig. 9. Then extendthe transmitterand receiver
antennas fully.
•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
servofollowsthe movementof the stick.
•Connect the pushrod to each servo horn, then check if the
directionof travelof each servomatches the directionof
operationof itstransmitterstick.To reversethe direction
ofservotravel,switchtheservoreversingswitch.
•Operate each servooveritsfullstroke,and check if the push-
rod binds or is too loose. Applyingunreasonableforceto the
servo horn will adversely affect the servo and quickly drain
the battery.Alwaysmake the travelof each controlmecha-
nism somewhatlargerthanthefulltravel(includingtrim)of
the servohorn. Adjust the servohorns so thatthey move
smoothly even when the trim lever and stick are operated
simultaneously inthe same direction.
•Bealert fornoise.
This set is noise-resistant,butis not completely immune to
noise.Werecommend theuse of noiselessparts.
•Wheninstallingtheswitchharness,cut a rectangularhole
somewhat largerthan the fullstrokeof the switchand install
the switchso thatitmoves smoothly fromON to OFF.This
alsoappliestotheswitchmount when theswitchis installed
insidethefuselageand is turnedon and offfromtheoutside
witha piece ofwire,etc.Installthe switch where itwill not
beexposed to engine oil, dust, etc.

•Even though the receiver antenna is long,donotcut or
bundle it.
•Installthe servossecurely. Tighten the mounting screws
until the rubber grommet is crushedslightly. If the screws
are too tight, the cushioningeffect will be adversely affect-
ed.
•The crystalcan be changed fromthe outsideof the receiver
case.Alwaysuse theFutaba transmitter/receivermatched
crystalsetto change the band.
•Spare servohornsare supplied. Use them as needed.
•Wrapthe receiverinsponge rubber. Waterproofand dust-
proofthe receiverby placingit ina plasticbag and wrapping
arubber band around the open end of the bag. Do thesame
with the receiver/servo battery.
•Use the rubber bands wrapped around the receiver to hold
the servoand switchleads.
•Aftermounting is complete,recheckeach part,then check
the range by makingthe transmitterantennaas shortas
possible,extendingthe receiverantennafully,and operating
the set froma distanceof20m to 30m. The movementof
each servoshouldfollowthe movement of each stickof the
transmitter.
•Aftermounting and checking are complete, takeyour model
to the shop whereyou purchased the set,or to an experienc-
ed radio controlmodeler,and askthem to teach youhow to
handle yourradiocontrolset in theproper manner and to
inspectyourset-upcarefully.
•To enjoyradio control models fully, besure to observe all
safety standards.
AILERONAND ELEVATOR DUAL (dual rate ON,
OFF) ADJUSTMENT (6NLKonly)
When the dual switchis setto ON, theservothrowismade
smallerby theamount shown by the hatched linesinFig. 10.
The servo throw can be set from40% to 100%of the total
travelby adjustingthe trimmernextto the switchwitha flat
bladed screwdriver.When the dual rateswitchis setto OFF,
the throwisnormal.Whendesiringa largerthrow,such asfor
spins, etc.,set the dual rate switchto OFFand adjustthe
throw mechanicallybyhorn androd adjustment. Set the
dual rateswitchto on forlevelflight and adjust the trimmer
fortherequiredamountof throw.
When thedualrateswitchisset to OFF, dualrate is set and
the throwbecomes large.
