•FEATURES
The FP-3EG is a high quality 3 channel, expanded digital proportional radio control set.
The receiver and servo power is a four-battery; 4.8V (Ni-Cad)/6.0V (Dry-Cell). The
transmitter power supply is 9.6V (Ni-Cad)/10.5V (Dry-Cell). 3FG with S24 servos
only comes with Ni-cads for both
TX
and RX. Speed and torque of our servo are the
highest in its class.
Transmitter FP-T3EG
•Rudder dual rate (dual-rate on, dual-rate
off). The desired rudder angle can be se-
lected when dual-rate on.
•Servo reversing switch
at rudder and
nd
throttle channel.
•Throttle and rudder mixing is adjustable
up to the limit point.
•Three channel transmitter. Third channel
has a click knob and can be conveniently
used as a subchannel.
•Throttle
lever
has a neutral
shift
device,
but can be instantly changed to a ratchet
type.
• Semi-open gimbal sticks provide maximum
feel.
• Neck band provided as standard. Comfortable operation is possible by hooking
the band around your neck.
•Seven pen-cell battery power supply can
also be changed to Ni-Cad battery (NT-8C).
• Beautiful exterior based on human engine-
ering. Easy-to-use design.
Servo FP-S24
•Highest output torque (4.5kg-cm/62.7oz-in.
or greater) of any servo in its class.
•Output
gear
is
supported
at
the
top
and
bottom by ball bearings for excellent
neutral characteristics, long life,
and
smooth operation.
• Large 20m/m diameter coreless motor features high torque near neutral and exact
tracking of even minute rudder movements.
• Indirect drive system extends the life
of
the potentiometer substantially.
• Watertight/dustproof.
Besides the FP-S24, FP-S27, watertight
servo is available with this system.

Receiver FP-R3F
•Miniature type, light, weight, rugged construction.
•Crystal is replaceable from the outside.
•3P mini-connectors are compatible with
existing sets.
•3 channel specifications.
•Newly developed receiver use Futaba Cus-
tom I/C, BA633. This I/C is extremely
stable against power supply voltage fluctuations.
•Adjacent frequency interference is mini-
mized by the use of an RF amplifier circuit
and ceramic filter.
