Flying Tips and Repairs

Consult local laws and ordinances before choosing a ﬂ ying location.

Flying Field

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

that you ﬂ y at a designated RC ﬂ ying ﬁ eld. Always avoid ﬂ ying near houses,

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

such as parks, schoolyards, or soccer ﬁ elds.

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.

Understanding 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 will see oscillation. If oscillation occurs, decrease

airspeed. If oscillation persists, refer to the Troubleshooting Guide for more

information.

Takeoff

Place the aircraft in position for takeoff (facing into the wind). Set your trans-

mitter in low rate and gradually increase the throttle from ¾ to full and steer

with the rudder. As the airplane gains speed, gently pull back on the elevator

and climb to a comfortable altitude. You may also set ﬂ aps to half travel for

shorter takeoffs.

Flying

Fly the airplane and trim it for level ﬂ ight at ¾ throttle with ﬂ aps up. After

adjusting trim in ﬂ ight do not touch the control sticks for 3 seconds. This allows

the receiver to learn the correct settings to optimize AS3X performance.

Landing

Tip: To prevent damage to the landing gear doors, it is recommended to

remove them when landing in tall grass.

Make sure to land the aircraft into the wind. Start to slow the model down to

an approach speed and set the ﬂ aps to half travel. If landing in windy condi-

tions, land at half ﬂ ap travel. If ﬂ ying in light winds, set ﬂ aps to full for ﬁ nal

approach. With ﬂ aps and retracts extended, ﬂ y the aircraft to approximately

36 inches (90 cm) or less above the runway, using a small amount of throttle

for the entire descent. 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.

Refer to the Dual Rates and expo chart for proper ﬂ ap to elevator mix to help

reduce the pitching tendency from ﬂ aps.

NOTICE: When using ﬂ aps with this airplane, down elevator to ﬂ ap mixing is

required. Failure to do so may result in loss of control or a crash.

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 airplane in direct sun-

light or a hot, enclosed area such as a car. Doing so can damage the foam.

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.

In Flight Trimming

During your ﬁ rst ﬂ ight, trim the aircraft for level ﬂ ight at 3/4 throttle. 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 al-

lows the receiver to learn the correct settings to optimize AS3X performance.

Failure to do so could affect ﬂ ight performance.
