Great Planes Edge 540 1.60-43cc Performance Series ARF - GPMA1414 - Manual (Page 4)

Radio Equipment
Since the Edge 540 1.60 ARF is a large model capable of
extreme aerobatics, standard servos should not be used to
operate the control surfaces. Servos with a minimum torque
rating of 98 oz-in [7.1kg-cm] are required except for the
throttle servo which may be operated by a standard servo.
The servos shown in this manual that are used for all of the
control surfaces are Futaba
® S3305 servos. A minimum of
six high torque servos and one standard servo (used for
throttle when installing a glow or gas engine) are needed to
complete the Edge:
o Futaba S3305 Servo High-Torque Standard w/Metal
Gears (FUMT0045)
o Futaba S9001 Servo Aircraft Coreless BB (FUTM0075)
Because of heavy loads on the control surfaces, heavy-
duty servo arms should be used on all of the control surface
servos. The throttle servo can use the servo arm supplied
with the servo. This manual shows the installation of Great
Planes 1.5” [38mm] aluminum single-sided servo arms. If the
rudder servos will be installed in the aft location, six arms will
be needed. If the rudder servos are installed in the forward
position, only four arms will be needed. See the building
instructions for details on the rudder servo positions.
o Great Planes Large Scale 1.5" Single Side Servo Arm
(GPMM1105)
The following servo extensions and Y-harnesses were
also used to build the Edge 540 1.60 ARF as shown in
the manual:
o Two 36” [914mm] servo extensions for elevator servos
(HCAM2726 for Futaba J-connector)
o Two 36” [914mm] servo extensions for rudder servos
when installed in the optional aft location (HCAM2726 for
Futaba J-connector)
o Two 24” [610mm] servo extensions for aileron servos
(HCAM2721 for Futaba J-connector)
o One 6” [152mm] servo extension for receiver battery pack
(HCAM2701 for Futaba J-connector)
o One 12” [305mm] servo extension for brushless ESC if
applicable (HCAM2711 for Futaba J-connector)
If using a radio system that does not support mixing of
the elevator, rudder, and aileron servos, Y-harnesses will
be required:
o Two Hobbico ® Pro HD Y-Harnesses for rudder and aileron
servos (HCAM2751 for Futaba J-connector)
o One Reversing Y-Harness for elevator servos (EMOM0027
for Futaba J-connector)
Note: The list of servo extensions and Y-harnesses is based
on the equipment we used to set up the Edge as detailed in
the manual. The length or quantity may vary depending on
the actual equipment being used, radio locations, etc.
A battery pack with a minimum of 1500mAh capacity should
also be used. When flying large models such as the Edge 540
1.60 ARF,
ALWAYS check the battery condition before each
flight. If you are installing a gas engine with an electronic
ignition module, a separate battery pack (the EI pack does
not need to be high capacity) will also be required in addition
to the battery pack used to power the receiver and servos.
o Hobbico HydriMax ™ 4.8V 2000mAh NiMH Flat AA Rx U
(HCAM6321)
A heavy-duty receiver switch and charge jack will also
be needed:
o Futaba Heavy-duty Switch Harness w/Charge Cord
(FUTM4385)
o Ernst Charge Receptacle Futaba J FM (ERNM3001)
If installing a gas engine, an additional switch (standard
size) and charge jack will also be needed:
o Futaba SWH13 Switch Harness & Charge Cord Mini J
(FUTM4370)
