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. Gradu-

ally increase the throttle to ¾ and steer with the rudder. As the tail comes off

the ground, pull back gently on the elevator and 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 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

To land the aircraft, ﬂ y the aircraft down to the ground using 1/4 –1/3

throttle to allow for enough energy for a proper ﬂ are. The aircraft is easiest to

land doing a wheel landing (two point), where the aircraft touches down on the

main landing gear ﬁ rst while the tailwheel is still off the ground. The aircraft

can also be landed in a three-point attitude, where all three wheels touch down

at the same time. When the aircraft touches down, reduce back pressure on

the elevator stick to prevent the plane from becoming airborne again.

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.

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 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 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.

WARNING:

Always decrease

throttle at propeller

strike.

Post Flight

Disconnect the ﬂ ight battery from the ESC (Required for Safety

and battery life).

2 Power OFF the transmitter.

3 Remove the ﬂ ight battery from the aircraft.

4 Recharge the ﬂ ight battery.

5 Repair or replace all damaged parts.

Store the ﬂ ight battery apart from the aircraft and monitor the

battery charge.

Make note of the ﬂ ight conditions and ﬂ ight plan results, planning for

future ﬂ ights.

Panic Recovery Mode

(If you have activated Panic recovery

during binding)

• If you feel you have lost control of

the aircraft, hold the Panic Recovery

button or switch and reduce throttle.

The SAFE

technology will return

the aircraft to upright ﬂ ight.

• Release the Panic Recovery button

to return to normal ﬂ ight with full

stick control again.

IMPORTANT: Always ﬂ y at a safe

altitude, as Panic Recovery may cause

the aircraft to lose some altitude when

leveling the wings.

IMPORTANT: If the aircraft is upside

down when the Panic Recovery button

is pressed, sufﬁ cient altitude is re-

quired for the aircraft to return to

upright ﬂ ight.
