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),

the control surfaces will react to aircraft movement. In some ﬂ ight conditions

oscillation may occur (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 in position for takeoff (facing into the wind). Select low rates

for ﬁ rst takeoff and gradually increase the throttle to full and steer with the nose

wheel. Allow the model to accelerate to ﬂ ying speed, then pull back gently on the

elevator and climb to a comfortable altitude.

Flying

Always choose a wide-open space for ﬂ ying. Due to the higher speeds of this

aircraft, it does require more room to ﬂ y than average foam models. It is ideal

for you to ﬂ y at a sanctioned ﬂ ying ﬁ eld. If you are not ﬂ ying at an approved site,

always avoid ﬂ ying near houses, trees, wires and buildings. You should also be

careful to avoid ﬂ ying in areas where there are many people, such as busy parks,

schoolyards, or soccer ﬁ elds.

In ﬂ ight 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 landing, adjust the linkages mechanically to account for trim

changes and then reset the trims to neutral. Ensure the aircraft will ﬂ y straight and

level with no trim or sub-trim.

Landing

For your ﬁ rst ﬂ ights with the recommended battery pack (EFLB32006S30), set

your transmitter timer or a stopwatch to 4 minutes. After 4 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 and

recharge the ﬂ ight battery. See the Low Voltage Cutoff (LVC) section for more

details on maximizing battery health and run time.

Turn the aircraft into the wind and reduce the throttle. Extend the landing gear and

ﬂ aps. The ﬂ aps will allow the aircraft to slow to a more manageable landing speed

while still maintaining lift. Elevator trim may be necessary to maintain level ﬂ ight

with the addition of ﬂ aps. Use the throttle during the landing approach to control

the rate of descent. Keep the wings level and the aircraft pointed into the wind.

As you approach the threshold of the runway and approximately 1 meter altitude,

decrease the throttle and begin your ﬂ are by easing back on the elevator. Continue

back pressure on the elevator to bring the aircraft down gently on the runway.

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 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 (DYNF0002, sold separately).

Repairs

Thanks to the EPO 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 .

NOTICE: Use of CA accelerator on your aircraft can damage paint. DO NOT

handle the aircraft until accelerator fully dries.

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.
