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 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 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 operat-
ing 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 core-
less servo have been realized by using a new small, high-
performance 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 vibra-
tion. The connector housing has a reverse insertion preven-
tion 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 re-
ceiver 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.
