The Giant P-47 Razorback ARF requires a servo to
operate the air control valve if using pneumatic retracts,
a throttle servo, two fl ap servos, two aileron servos,
two elevator servos and a rudder servo. Servos with a
minimum of 50 oz-in [3.9kg-cm] of torque are required
for operating the elevators, rudder, ailerons and fl aps.
We recommend that metal geared servos also be used.
Standard servos may be used for the throttle and choke
(the servo operated choke is optional). A micro servo
is required to operate the retract air valve. An optional
servo operated kill switch may also be used (this is in
addition to the manually operated engine kill switch.
A servo operated kill switch is only really necessary
for engines that do not reliably shut off by closing the
carburetor, but could also serve as a backup.

A receiver battery with a minimum of 1,000mAh is
recommended for fl ying the Giant P-47 Razorback
ARF. The battery voltage should be checked before
every fl ight to be certain it has enough “charge”.
In addition to the servos, the following items (or similar
items) are also required. The order numbers shown
in parentheses are for Futaba servos.

Note: The length and quantity of servo extensions
and Y-connectors may vary depending on the brand
of radio you are using and the radio installation.
The instructions show the two aileron servos
connected with a Y-harness that is plugged into the
aileron channel of the receiver. If using a computer
radio, the two aileron servos can be plugged into
separate channels of the receiver and mixed together.
The two fl ap servos and the two elevator servos also
use a Y-harness. If plugging the servos into separate
channels, follow the instructions included with your
radio system on how to mix the channels.
S.BUS SYSTEM
A cutting edge alternative to standard
servo installation!
The innovative Futaba S.Bus system lets you unleash
your fl ight system’s full potential and cut down on
cable clutter at the same time. It uses digital serial
data communication technology to transmit control
signals between your receiver and servos. A single
S.Bus cable can carry signals to as many channels
as your transmitter can handle. You no longer have to
worry about plugging in the wrong servo to the wrong
channel, because each servo knows what channel it
is dedicated to in advance.
SBD-1 S.Bus Decoder Cables allow the use of existing
analog and digital servos, too. By providing today’s
pilots with tomorrow’s technology, the Futaba S.Bus
system is nothing short of revolutionary.
