Consult local laws and ordinances before choosing a ying location.
Range Check your Radio System
Before you y, range check the radio system. Refer to your specic transmitter
instruction manual for range test information.
Oscillation
Once the AS3X system is active (after advancing the throttle for the rst time),
you will normally see the control surfaces react to aircraft movement. In some
ight conditions you may see oscillation (the aircraft rocks back and forth on
one axis due to overcontrol). If oscillation occurs, refer to the Troubleshooting
Guide for more information.
Hand Launching
Use the “handle” to hold the aircraft in one hand and the transmitter in the
other. Apply 1/3 - 1/2 throttle and throw the aircraft directly into the wind,
angled slightly up (5 to 10 degrees above the horizon). Climb to a safe altitude
and check the trim.
Flying
For your rst ights with the recommended battery pack (EFLB22003S30), set
your transmitter timer or a stopwatch to 4 minutes, land the aircraft. Adjust
your timer for longer or shorter ights once you have own the model. If at
any time the motor power reduces, land the aircraft immediately to recharge
the ight battery. See the Low Voltage Cutoff (LVC) section for more details on
maximizing battery health and run time.
Landing
Land the aircraft into the wind. Use high rate Elevator for landings. Use a small
amount of throttle for the entire descent.
Keep the throttle on until the aircraft is ready to are. During are, keep the
wings level and the aircraft pointed into the wind. Gently lower the throttle
while pulling back on the elevator to bring the aircraft down on its belly.
Using a grass landing area will lesson the chance of damage to the aircraft.
NOTICE: If a crash is imminent, reduce the throttle and trim fully. Failure to do
so could result in extra damage to the airframe, as well as damage to the ESC
and motor.
NOTICE: After any impact, always ensure the
receiver is secure in the fuselage. If you replace
the receiver, install the new receiver in the same
orientation as the original receiver or damage may
result.
NOTICE: Crash damage is not covered under
warranty.
NOTICE: When you are nished ying, never leave
the aircraft in direct sunlight or in a hot, enclosed
area such as a car. Doing so can damage the
aircraft.
Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V per cell, it will not hold a charge.
The ESC protects the ight battery from over-discharge using Low Voltage
Cutoff (LVC). Before the battery charge decreases too much, LVC removes
power supplied to the motor. Power to the motor reduces, showing that some
battery power is reserved for ight control and safe landing.
Disconnect and remove the Li-Po battery from the aircraft after use to prevent
trickle discharge. Charge your Li-Po battery to about half capacity before
storage. During storage, make sure the battery charge does not fall below 3V
per cell. LVC does not prevent the battery from over-discharge during storage.
NOTICE: Repeated ying to LVC will damage the battery.
Tip: Monitor your aircraft battery’s voltage before and after ying by using a
Li-Po Cell Voltage Checker (EFLA111, sold separately).
Repairs
Thanks to the EPO material in this aircraft, repairs to the foam can be made
using virtually any adhesive (hot glue, regular CA, epoxy, etc). When parts are
not repairable, see the Replacement Parts List for ordering by item number. For
a listing of all replacement and optional parts, refer to the list at the end of this
manual.
NOTICE: Use of CA accelerant on your aircraft can damage paint. DO NOT
handle the aircraft until accelerant fully dries.
WARNING:
Always decrease
throttle at propeller
strike.
Flying Tips and Repairs
PNP Receiver Selection and Installation
The Spektrum AR636 receiver is recommended for this airplane. If you choose
to install another receiver, ensure that it is at least a 6-channel full range
(sport) receiver. Refer to your receiver manual for correct installation and
operation instructions.
CAUTION: When using a Futaba
®
transmitter with a Spektrum DSM
module, you must reverse the throttle channel and rebind. Refer to
your Spektrum module manual for binding and failsafe instructions. Refer
to your Futaba transmitter manual for instructions on reversing the throttle
channel. All ight surfaces must also be checked for the correct direction.
Installation (AR636 shown)
1. Remove the canopy from the fuselage.
2. Mount the receiver parallel to the length of the fuselage as shown. Use double-
sided servo tape.
3. Attach the appropriate control surfaces to the their respective ports on the
receiver using the chart in the illustration.
CAUTION: Incorrect installation of the receiver could cause a crash.
