FEATURES OF MAGNUM JUNIOR

The Magnum series are pistol grip type of AM 2 channel digital propor-
tional radio control sets and are the best in their class.

TRANSMITTER FP-T2PKA, (FP-T2PK)_____________

• Newly designed cockpit type control panel
• Human-engineered size and design are easy to use.
•Steering rate adjuster The steering servo travel volume (right 81 left

evenly from neutral) can be adjusted simultaneously, while running.

•Throttle ATV The throttle servo travel volume can be adjusted

and set with two trimmers, independently. FP-T2PKA

• Wheel angle adjuster. The turning angle of the steering wheel can

be increased and decreased. This allows operation at the best angle

• Neutral adjuster. The throttle trigger throttle stroke/brake deflection

stroke (back stroke) can be freely selected to match the application

•Servo reversing switch (steering and throttle) is standard Each servo

can be reversed from the outside. This is extremely convenient when
connecting the linkages.

• Since a level meter is provided, battery consumption can be seen at

a glance.

• Crystal can be changed from the outside. Crystal can be immediately

changed during competitions, etc. except 

72 MHz and 75 MHz on

transmitter.

• Power supply can be changed to a nicad battery system. FP-T2PKA

RECEIVER FP-R102GR_____________________

• BEC (Battery Eliminator Circuitry) system allows sharing of the

running Nicd battery and eliminates the need for a regulator and

diode.

• Crystal socket uses a new type of highly reliable subminiature

pins. Reliability is increased and the crystal can be changed from
the outside.

RECEIVER FP-R104H_______________________

• 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.

• Short (50cm) antenna designed for miniature models is easy to mount.

(27MHz only)

• Narrow band design using a narrow band ceramic filter resists adjacent

channel interference.

• Noise resistance achieved by using a pulse noise rejection circuit.
• New CMOS miniature 1C used in the data coder increases reliability

substantially.

• New type sub miniature, highly reliable pins used at the  c r y s t a l 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-S148, S129, S132H

•Motor uses the newest helical type rotor for improved output torque

and smooth operation. (S148, S129)

• These heavy-duty & water/dust tight servos are designed for use with

Futaba digital proportional radio control sets (S129)

• New indirect driver potentiometer improves vibration and shock re-

sistance and increases neutral precision tremendously.

• Futaba low-power custom 1C provides high starting torque, narrow

dead band, and excellent trackability.

• Fiberglass-reinforced PBT (polybutylene terephthalate) injection

molded servo case is mechanically strong and invulnerable against
glow fuel.

• Strong polyacetal resin ultra-precision servo gear features smooth

operation, positive neutral, and very  l i t t l e backlash.

• Fiberglass-reinforced epoxy resin PC board with thru-the-hole plating

improves servo amp vibration and shock resistance.

• Thick film gold-plated connector pins eliminate poor contact and

improve reliability against shock and vibration.

• Special grommet bushing simplifies servo mounting and improves the

cushioning  e f f e c t .

• Six special adjustable splined horns are available.

• Maximum output torque of 48.7oz-in.(3.0kg-cm/3 5kg-cm) allows

use in almost any model (S148, S129)

• High operating speed of 0.13 sec/60° makes it perfect when especially

high speed is necessary. (S132H)
