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
a 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 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
• Reliability substantially improved by using industrial robots
to assemble the PC board.
• Servo reversing switch for each channel. Servos are reversed
by using this switch.
• Newly designed open gimbal sticks operate smoothly and
positively.
Spring tension mechanism allows adjustment of the operating feel of the stick lever.
• Nonslip adjustable lever head allows adjustment of the stick
length as desired.
• RF PC board module style system in transmitter.
• Functional case, created as a result of the exhaustive pursuit
of
easier
operation,
has
evolved a thick
case
which
fits
into
the palm of the hand.
•Aileron, Elevator dual rate function. (Dual rate ON, OFF)
(6NLK)
• Easy to read square transmitter battery voltage/output level
meter.
• Excellent radiation efficiency, strong 8-stage telescoping
antenna.
• Neck strap bracket provided as standard. Operation is easier
if the transmitter is hung from your neck by using the
optional neck strap.
• Built-in NiCad battery.
RECEIVER FP-R7H (6NLK)
•A compact, lightweight, rugged 7-channel receiver virtually
invulnerable to power supply voltage changes thanks to new
Futaba Custom 1/C, IR-2501.
•Newly designed AGC circuit minimizes interference and dead
points.
•Fiberglass reinforced epoxy resin PC board with thru-thehole plating improves vibration and shock resistance.
•Three-wire gold-plated mini block connector is compatible
with all Futaba servos.
RECEIVER FP-R4F (4NL)
•Compact, lightweight, rugged construction.
•Three-wire gold-plated mini block connector is compatible
with all Futaba servos.
• Four channel.
RECEIVER FP-R4H,
(4NL)_______________
• High performance AM 4 channel receiver in which miniature
size and light weight have been achieved by using the PC
board space to the maximum.
•
Narrow band design using a narrow
band
ceramic
filter-
resists adjacent channel interference.
• Noise resistance achieved by using a pulse noise rejection
circuit.
• New C MOS miniature IC used in the data coder increases
reliability substantially.
• New type subminiature, highly reliable pins used at the
crystal socket also increase reliability. The crystal can be
changed from the outside.
• Thick film gold-plated connector pins eliminate poor contact
and improve reliability against shock and vibration.
SERVO FP-S38
Very-precise neutral, small, rugged servo
• 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 molded servo case is mechanically strong and invulnerable to glow fuel.
• Strong polyacetal resin ultra-precision servo gear features
smooth operation, positive neutral, and very little backlash.
•
Fiberglass
reinforced epoxy resin
PC
board
with
thru-thehole plating improves servo amp vibration and shock resistance.
• Three wire-gold-plated 3p mini connector.
•Special grommet simplifies mounting of the servo and has
an excellent cushioning effect.
•Six
special
adjustable
splined horns.
• High 34.8 oz. in (2.5kg-cm) maximum output torque allows
use in almost any model.

Aileron dual rate ON-OFF switch. When set to the upper
position, dual rate is turned on, and when set to the lower
position, dual rate is turned off.
Aileron dual rate trimmer (6NLK only)
This trimmer sets the aileron travel when the aileron dual
switch is set to on. When the dual switch is set to ON, the
servo throw can be set to an arbitrary angle smaller than
when the dual switch is OFF (normal) as shown in the
figure. Use the throw matched to the aircraft and the
maneuvers to be performed.
