6. If you are not an experienced pilot or have not fl own this type
of model before, we recommend that you get the assistance
of an experienced pilot in your R/C club for your fi rst fl ights.
If you’re not a member of a club, your local hobby shop has
information about clubs in your area whose membership
includes experienced pilots.
We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fl yability of your fi nished model depends
on how you build it; therefore, we cannot in any way
guarantee the performance of your completed model,
and no representations are expressed or implied as to
the performance or safety of your completed model.
Remember: Take your time and follow the instructions to
end up with a well-built model that is straight and true.
LITHIUM BATTERY
HANDLING & USAGE
WARNING!!
Read the entire instruction sheet included with
the battery. Failure to follow all instructions could cause
permanent damage to the battery and its surroundings, and
cause bodily harm!
• ONLY use a LiPo approved charger. NEVER use a NiCd/
NiMH peak charger!
• NEVER charge in excess of 4.20V per cell.
• ONLY charge through the “charge” lead. NEVER charge
through the “discharge” lead.
• NEVER charge at currents greater than 1C.
• ALWAYS set charger’s output volts to match battery volts.
• ALWAYS charge in a fi reproof location.
• NEVER trickle charge.
• NEVER allow battery temperature to exceed 150° F (65° C).
• NEVER disassemble or modify pack wiring in any way or
puncture cells.
• NEVER discharge below 2.5V per cell.
• NEVER place on combustible materials or leave unattended
during charge or discharge.
• ALWAYS KEEP OUT OF REACH OF CHILDREN.
DECISIONS YOU MUST MAKE
This is a partial list of items required to fi nish the Synapse ARF
that may require planning or decision making before starting
to build. Order numbers are provided in parentheses.
Radio Equipment & Electronics
The Synapse ARF requires a transmitter that supports elevon
mixing, a micro receiver, and two micro servos (9g or less). If
you already have a transmitter you are going to use to fl y the
Synapse, you can get the receiver and servos separately:
❏
Futaba R114F 4-channel FM micro receiver w/o crystal
(low band - FUTL0442, high band - FUTL0443)
❏
Futaba FM single conversion receiver crystal for R114F
(low band - FUTL62**, high band - FUTL63**)
❏
Futaba S3114 micro HT servo (FUTM0414)
Or, you can purchase a complete system (including transmitter)
specially packaged for park fl yers. If purchasing a complete
system, the Futaba 3FR Skysport (FUTJ53**) single-stick
radio is suitable. It comes with a micro receiver and two Futaba
S3108 micro servos. The transmitter is also equipped with a
rechargeable NiCd battery pack.
A lithium-polymer battery pack and suitable charger are
also required. Although there are different battery packs and
chargers available that will work with the Synapse ARF, the
economical choices recommended by Great Planes are:
❏
Great Planes 11.1V 910mAh LiPo 20C Discharge
(GPMP0605)
❏
Great Planes ElectriFly DC Lithium Polymer Charger
(GPMM3010)
❏
Great Planes Equinox
™
Cell Balancer (GPMM3160)
Note:
The Great Planes 11.1V 1250mAh 20C LiPo with
balance connector (GPMP0609) will also fi t inside the radio
compartment of the Synapse. The 1250mAh pack will result
in a forward C.G. position, and the 910mAh pack will provide
a more aft C.G. position.
Speed Control
A brushless electronic speed control with BEC (Battery
Eliminator Circuitry) is required. The BEC allows both the
motor and the radio system to be powered by the same
battery (thus eliminating the on-board receiver battery). The
Great Planes Silver Series 25A Brushless ESC 5V/2A BEC
(GPMM1820) is recommended.
Motor
For optimum performance, the Great Planes 20-40-3500
Ammo Brushless Motor (GPMG5140) is recommended. If
you plan to use the Great Planes Silver Series 25A Brushless
ESC, you will also need to purchase the Great Planes Bullet
Adapters 3.5mm Male/2mm Female (GPMM3122).
