5. You must check the operation of the model before every
fl ight to insure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
pushrod connectors or servo arms often and replace them if
they show any signs of wear or fatigue.
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 L-39 EDF ARF
that may require planning or decision making before starting
to build. Order numbers are provided in parentheses.
Radio Equipment
The L-39 EDF ARF requires a 3+ channel transmitter, a micro
receiver, and three micro servos (9g or less). If you already
have a transmitter you are going to use to fl y the L-39, 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)
❏
Two Futaba 150mm Slim Wire Extensions (FUTM4506)
❏
Futaba 6" Dual Servo Extension J (FUTM4130)
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 L-39 ARF, the
economical choices recommended by Great Planes are:
❏
Great Planes LiPo 11.1V 910mAh 20C Discharge
w/Balance (GPMP0605)
❏
Great Planes LiPo 11.1V 1250mAh 20C Discharge
w/Balance (GPMP0609)
❏
Great Planes ElectriFly DC peak charger (GPMM3010)
❏
Great Planes Equinox ™ Cell Balancer (GPMM3160)
Note: Battery choice will affect the balance of the plane. 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 25A 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 (GPMM1820)
is recommended.
