Futaba
DIGITAL PROPORTIONAL
RADIO CONTROL
AM
Thank you for purchasing a Futaba digital proportional radio control set.
Please read this manual carefully before using your set.
FEATURES OF FP-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 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-T4NBL______________
• Servo reversing switch for each channel. Servos are reversed
by using this switch.
• Newly designed 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.
• 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.
• Easy to read transmitter battery voltage/output level meter.
• Neck strap bracket provided as standard. Operation is easier
if the transmitter is hung from your neck by using the neck
strap.
• Nicad operation as standard.
RECEIVER FP-R114H
• 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 ceramic filter improves rejection of adjacent
channel interference.
FEATURES OF MCR-4A RECEIVER
• Narrow band design using a narrow band ceramic filter.
FEATURES OF MCR-4A AMP
• Built-in heat protector prevents overheating of the amplifier
by a continuous overcurrent.
• Motor idle or maximum slow can be arbitrarily set at the
transmitter throttle stick maximum slow position by built-in
idle point trimmer.
SERVO FP-S148 RUGGED, LOW-PROFILE SERVO
• Vibration and shock resistance have been improved further
by using a direct wiring system which directly connects the
servo amp, motor and potentiometer.
•
The height of the
servo
has
been
reduced and
high
torque,
high speed, and smooth movement equal to that of the coreless servo have been realized by using a new small, highperformance motor. (Output torque 3kg.cm, operating
speed 0.22 sec/60°).
SERVO FP-S133 HIGH-QUALITY MICROSERVO_
• Futaba hybrid custom 1C provides high starting output
torque, narrow dead-band, and excellent trackability.
• Thick film gold plated connector pins insure positive contact
connector shape increase reliability against shock and vibration. The connector housing has a reverse insertion prevention mechanism.
• Adjustable (splined) horn permits arbitrary setting of the
neutral position.
• Despite being a microservo, operating speed is a fast 0.21
sec/ 60° and output torque is a high 2.2 kg/cm.
SET CONTENTS AND RATINGS
(Specifications are subject to change without prior notice.)
RECEIVER WITH LINEAR CONTROLLER MCR-4A
• FET amplifier with miniature lightweight AM 4-channel receiver and motor controller in one pack.
• Since the drive motor power supply (7.2 V NiCd battery
pack, etc.) can also be used to power the receiver and servos,
troublesome wiring is unnecessary and the model can be
made lighter.
• Built-in high performance low voltage "autocut" circuit pre-
vents loss of control due to power supply voltage drop
during flight.
• Since the motor speed can be controlled steplessly from
maximum alow to high, acrobatics equal to those of engine
aircraft can be reproduced even with a motor aircraft.
