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, decrease airspeed. If oscilla-

tion persists, refer to the Troubleshooting Guide for more information.

ROG 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

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

the elevator and climb to a comfortable altitude.

Hand launch

It is advisable to have a helper for the ﬁ rst few hand launches. Hold the

airplane behind the wing with the throwing hand and support the nose with the

opposite hand. Run the motor up to full throttle and give a FIRM throw straight

ahead. The aircraft should be launched ﬁ rmly with the nose up 5–10 degrees

and directly into the wind.

Flying

If this is your ﬁ rst ducted fan aircraft, just remember that because there is no

prop blast blowing air over the control surfaces, the controls will not be as

responsive at low speeds. The aircraft is easy to ﬂ y, but because it can reach a

very high speed, plan your ﬂ ight path to avoid obstacles or people.

Fly the aircraft and trim it for level ﬂ ight at 3/4 throttle. 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.

Tip: If using more than 8 clicks of ﬂ ight trim, mechanically adjust the linkage

so less trim is needed, or AS3X operation may be affected.

Landing

For your ﬁ rst ﬂ ights with the included or recommended battery pack

(EFLB32004S30), set your transmitter timer or a stopwatch to 4 minutes. After

4 minutes, land the aircraft. If at any time the motor pulses, land the air-

craft immediately to recharge the ﬂ ight battery. See the Low Voltage Cutoff

(LVC) section for more details on maximizing battery health and run time.

Land the aircraft into the wind. Approach the runway at 1/4 to 1/8 throttle. Use

the power to control altitude and the elevator to control angle of attack. Once

your glide path is established, ﬂ y the aircraft down to about a foot (30 cm) off

the runway. Gradually reduce power and ﬂ are the aircraft to touch down on the

main wheels ﬁ rst. Reduce elevator input to set the nosewheel on the ground

and steer with the rudder stick until the aircraft has come to a stop.

Belly Landing

If landing on grass without the landing gear, use the same approach as if

ﬂ ying with landing gear. Start your ﬂ are with the power off about 1 foot (30

cm) above the ground and hold the nose off until the tail touches down. Try to

keep the wings level to prevent clipping a wing on the ground.

CAUTION: Always lower the throttle after

landing to avoid accidental intake of materials,

which could result in possible damage to the rotor and/

or motor and cause personal injury.

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 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.

NOTICE: Always

decrease throttle at

ground contact.
