Flying Tips and Repairs

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.

Hand Launch

Set your dual rate switches to low rate. Hold the aircraft fuselage under the

wing and gradually increase the throttle to ¾. Launch the aircraft into the wind

with the wings level. Allow the aircraft to climb to a comfortable altitude.

Flying

Always choose a wide-open space for  ying your aircraft. It is recommended

that you  y at a designated RC  ying  eld. Always avoid  ying near houses,

trees, wires and buildings. Avoid  ying in areas where there are many people,

such as parks, schoolyards, or soccer  elds.

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.

After landing, adjust the linkages mechanically to account for trim changes and

then reset the trims to neutral. Ensure the aircraft will  y straight and level

with no trim or sub-trim.

Landing

For your  rst  ights with the recommended battery pack (EFLB13503S30), set

your transmitter timer or a stopwatch to 7 minutes. After 7 minutes, land the

aircraft. Adjust your timer for longer or shorter  ights once you have  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.

Make sure to land into the wind. Due to the high lifting

ef ciency of the sailplane design, landing requires a

large landing area. While on your downwind leg, remem-

ber that the sailplane glides much better than other air-

craft. You will need to setup for landing lower and with a

more shallow descent than you may be used to. As you

are on approach for landing, ensure that the model is

descending slowly, but also not accelerating. Maintain

this descent and speed, and, as the model nears the

ground (approximately 6 inches (15 cm)), slowly apply a

small amount of up elevator. Before the aircraft touches

down, always fully decrease throttle to avoid damage to

the propeller, motor, ESC or other components.

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 pulses, 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 stor-

age. 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 Z-Foam

™

material in this aircraft, repairs to the foam can be

made using virtually any adhesive (hot glue, regular CA, epoxy, etc). The hori-

zontal tail is not made of the same material, so use only foam-compatible

CA on the horizontal tail.

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.

Wind

During your  rst  ight, trim the aircraft for level  ight at 3/4 throttle with

 aps and gear up. Make small trim adjustments with your transmitter’s trim

switches to straighten the aircraft’s  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  ight performance.
