Flying Tips and Repairs

Consult local laws and ordinances before choosing a fl ying location.
Range Check your Radio System
Before you fl y, range check the radio system. Refer to your specifi c transmitter
instruction manual for range test information.
Oscillation
Once the AS3X system is active (after advancing the throttle for the fi rst time),
you will normally see the control surfaces react to aircraft movement. In some
fl 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.
Takeoff
Place the aircraft facing into the wind. Set your transmitter in low rate.
Gradually increase the throttle to ¾ and steer with the rudder. As the tail
comes off the ground, pull back gently on the elevator. When airborn, climb to a
comfortable altitude.
Flying
For your fi rst fl ights with the recommended battery pack (EFLB22003S30), set
your transmitter timer or a stopwatch to 5 minutes. After fi ve minutes, land the
aircraft. Adjust your timer for longer or shorter fl ights once you have fl own the
model. If at any time the motor power reduces, land the aircraft immediately to
recharge the fl 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 a small amount of throttle for the entire
descent. Lower the throttle to approximately ¼.
Keep the throttle on until the aircraft is ready to fl are. During fl 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 wheels.
If landing on grass, it is best to hold full up elevator after touchdown and when
taxiing to prevent nosing over.
Once on the ground, avoid sharp turns until the plane has slowed enough to
prevent scraping the wingtips.

PNP Receiver Selection and Installation

The Spektrum AR636A receiver is recommended for ths 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
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 fl ight surfaces must also be checked for the correct direction
Installation (Spektrum AR636 receiver installation 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. Insert the servo plugs into the appropriate ports on the receiver.
4. Confi rm control stick inputs and gyro response to aircraft movements
results in proper control surface movement.
CAUTION: Incorrect installation of the receiver could cause a crash.
Always confi rm proper control surface movement any time changes are
made to the transmitter, receiver, or servos.

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 fi nished fl 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 fl 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 fl 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 fl ying to LVC will damage the battery.
Tip: Monitor your aircraft battery's voltage before and after fl ying by using a
Li-Po Cell Voltage Checker (EFLA111, sold separately).
Repairs
Thanks to the Z-Foam ™ 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.
