Great Planes 27% Extra 330S ARF - GPMA1413 - Manual (Page 6)

6 6
Radio Equipment
Six servos with a minimum torque of 98 oz-in are required–
one for each aileron, one for each elevator and two for the
rudder. A standard servo may be used on the throttle. Futaba
®
S3305 servos (FUTM0045) are shown on the model in this
manual because they are a suitable, relatively economical
solution to the high-torque requirements, but there are also
higher-precision servos available if this is your preference.
The elevator servos in the Great Planes Extra 330S 1.60
ARF move in opposition, so if the radio you will be using is not
capable of electronically mixing the elevator servos (so that
they may be connected to different channels in the receiver
and one of them reversed), an on-board servo reverser such
as the Futaba SR-10 Dual Servo Reverser (FUTM4150) will
be required.
A receiver battery pack with a minimum capacity of 1500mAh
must also be used. The HydriMax
™ Ultra 4.8V 2000mAh
battery pack (HCAM6321) is suitable.
Following are the servo extension wires, Y-harnesses and
other radio gear illustrated in this manual:
❏
(2) 24" [610mm] servo extensions for the ailerons
(HCAM2721 for Futaba, HCAM2720 for JR/Hitec)
❏
(2) additional 24" [610mm] servo extensions for the
elevators if mounting the receiver in the aft radio tray
–or–
❏
(2) 36" [914mm] servo extensions for the elevators if
mounting the receiver in the forward radio tray (HCAM2726
for Futaba, HCAM2725 for JR/Hitec)
❏
(2) more 24" [610mm] servo extensions for the rudder
servos if mounting them in the aft location under
the horizontal stabilizer and using the aft radio tray
(HCAM2721 for Futaba, HCAM2720 for JR/Hitec)
–or–
❏
(2) 36" [914mm] servo extensions for the rudder servos
if mounting them in the aft location under the horizontal
stabilizer and using the forward radio tray (HCAM2726 for
Futaba, HCAM2725 for JR/Hitec)
❏
(2) Dual servo connectors such as Futaba Dual Servo
Extension Futaba J (FUTM4130) for rudder servos and
aileron servos
This model was also designed to accommodate two Ernst
Charge Receptacles (ERNM3001 for Futaba J, ERNM3004
for JR) for charging the batteries and monitoring the voltage
without having to remove the canopy hatch. If not using a gas
engine with an ignition battery, only one charge receptacle
will be required (for the receiver battery).

Drill bits: 1/16" [1.6mm], 3/32" [2.4mm], 1/8" [3.2mm], and
if your servos have 3mm screws that hold on the servo
arms (such as the Futaba 3305s) you will also need a #32

Covering Tools
A Top Flite ® MonoKote ® or 21st Century ® model airplane
covering iron with a protective covering sock will be necessary
for tightening any covering on the model that may have loosened
or formed wrinkles between the time of production and your
purchase. The 21st Century iron is preferred as it has a longer
cord and a rounded, contoured shoe. A trim iron is not as much
of a necessity, but would still be handy for sealing the edges
down inside servo openings and other small areas.
