Center of Gravity (CG)
The CG location is measured from the leading edge of the wing at the root.
This CG location has been determined with the recommended Li-Po battery
(EFLB22003S30) installed to the front edge of the battery tray.
Tip: Measure the CG with the aircraft inverted.
AS3X Control Direction Test
85mm +/-3
back from leading
edge at the root.
This test ensures that the AS3X® control system is functioning properly.
Assemble the aircraft and bind your transmitter to the receiver before
performing this test.
1. Raise the throttle just above 25%, then lower the throttle to activate AS3X.
CAUTION: Keep all body parts, hair and loose clothing away from a
moving propeller, as these items could become entangled.
IMPORTANT: The AR636 programming for this aircraft increases control
surface movement when fl aps are fully down.
2. Move the entire aircraft as shown and ensure the control surfaces move in
the direction indicated in the graphic. If the control surfaces do not respond
as shown, do not fl y the aircraft. Refer to the receiver manual for more
information.
Once the AS3X system is active, control surfaces may move rapidly. This is
normal. AS3X remains active until the battery is disconnected.

In Flight Trimming
During your fi rst fl ight, trim the aircraft for level fl ight at 3/4 throttle with
fl aps and gear up. Make small trim adjustments with your transmitter’s trim
switches to straighten the aircraft’s fl ight path.
After adjusting trim do not touch the control sticks for 3 seconds. This allows
the receiver to learn the correct settings to optimize AS3X performance.
Failure to do so could affect fl ight performance.
Flying Tips and Repairs
EN
3 Seconds
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 and
use your fl aps switch to drop the fl aps to takeoff or “half position”. Gradually
increase the throttle to ¾ and steer with the rudder. Flaps make takeoffs shorter. As the tail comes off the ground, pull back gently on the elevator.
When airborne, fl ip your gear switch to raise your landing gear. Climb to a
comfortable altitude and then fl ip your fl aps switch to level the fl aps.
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 pulses, 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 high rate Elevator for landings. Use a small
amount of throttle for the entire descent. Lower the throttle to ¼ and fl ip your
fl aps switch to deploy the fl aps to the landing or “full down position”. Flaps
will make the landing approach steeper and slower, and allow for a
smoother landing. Flip your gear switch to lower your landing gear. This will
slow the aircraft further.
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.
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.
WARNING:
Always decrease
throttle at propeller
strike.
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 pulses, 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.
