FEATURES OF FP-4NBL

The FP-4NBL is a 4 channel AM proportional radio control

set

with

an

ergonomic
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.

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.

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

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.
