Transmitter and Receiver Binding

Binding is the process of programming the receiver to recognize the GUID
(Globally Unique Identifi er) code of a single specifi c transmitter. You need to
‘bind’ your chosen Spektrum
transmitter to the receiver for proper operation.

IMPORTANT: Before binding a transmitter, read the Transmitter Setup section
of this manual to ensure that your transmitter is properly programmed for this
aircraft.

™

DSM2®/DSMX® technology equipped aircraft

Binding Procedure

IMPORTANT: The included AR636 receiver has been programmed for
operation specifi cally for this aircraft. Refer to the receiver manual for cor­rect setup if the receiver is replaced or is used in another aircraft.

Read the transmitter instructions for binding to a receiver (location of
transmitter’s Bind control). Please visit www.bindnfl y.com for a com-

plete list of compatible transmitters.

CAUTION: When using a Futaba® transmitter with a Spektrum DSM

module, you must reverse the throttle channel and rebind. Refer to your
Spektrum module manual for binding and failsafe instructions. Refer to

your Futaba transmitter manual for instructions on reversing the throttle
channel.

1. Make sure the transmitter is powered off.

2. Move the transmitter controls to neutral (fl ight controls: rudder,
elevators and ailerons) or to low positions (throttle, throttle trim).**

3. Install a bind plug in the receiver bind port.

4. Connect the fl ight battery to the ESC. The ESC will produce a series
of sounds. One long tone, then 3 short tones confi rm that the LVC is
set correctly for the ESC. The orange bind LED on the receiver will
begin to fl ash rapidly.

5. Power on the transmitter while holding the transmitter bind button
or switch. Refer to your transmitter’s manual for binding.

6. When the receiver binds to the transmitter, the orange bind light on
the receiver will turn solid and the ESC will produce a series of three
ascending tones. The tones indicate the ESC is armed, provided the
throttle stick and throttle trim are low enough to trigger arming.

7. Remove the bind plug from the bind port.

8. Safely store the bind plug (some owners attach the bind plug to their
transmitter using two-part loops and clips).

9. The receiver should retain the binding instructions received from the
transmitter until another binding is done.

* The throttle will not arm if the transmitter’s throttle control is not put at
the lowest position. If you encounter problems, follow the binding instruc­tions and refer to the transmitter troubleshooting guide for other instruc­tions. If needed, contact the appropriate Horizon Product Support offi ce.

**Failsafe

If the receiver loses transmitter communication, the failsafe will activate.
When activated, the airplane controls return to the neutral position estab­lished during step 2 of the binding procedure.

Battery Installation and ESC Arming

EN

Battery Selection

We recommend the E-fl ite® 2200mAh 11.1V 3S 30C Li-Po battery
(EFLB22003S30). Refer to the Optional Parts List for other recommended
batteries. If using a battery other than those listed, the battery should be within
the range of capacity, dimensions and weight of the E-fl ite Li-Po battery packs
to fi t in the fuselage. Be sure the model balances at the recommended CG.

1. Lower the throttle and throttle trim to the lowest settings. Power on the
Transmitter, then wait 5 seconds.

2. Apply the loop side (soft side) of the hook and loop tape (A) to the bottom of

your battery.

3. Carefully lift the back of the canopy hatch (B) to remove.

4. Install the fully charged battery (C) in the battery compartment as shown.

See the Adjusting the Center of Gravity instructions for more information.

5. Make sure the fl ight battery is secured using the hook and loop strap (D).

6. Connect the battery to the ESC (the ESC is now armed).

7. Keep the aircraft immobile and away from wind or the system will
not initialize.

• The ESC will sound a series of tones (refer to step 6 of the binding
instructions for more information).

• An LED will light on the receiver.

If the ESC sounds a continuous double beep after the fl ight battery is
connected, recharge or replace the battery.

8. Reinstall the canopy hatch.

CAUTION: Always

keep hands away from
the propeller. When
armed, the motor will turn
the propeller in response
to any throttle movement.

EN

Center of Gravity (CG)

The CG location is measured from the leading edge of the wing at the root.
This CG location has been determined with the recommended Li-Po battery
(EFLB22003S30) installed centered in the battery compartment.

AS3X Control Direction Test

62mm +/-3

back from lead­ing edge at
the root.

This test ensures that the AS3X® control system is functioning properly.
Assemble the aircraft and bind your transmitter to the receiver before
performing this test.

1. Raise the throttle just above 25%, then lower the throttle to activate AS3X.

CAUTION: Keep all body parts, hair and loose clothing away from a mov­ing propeller, as these items could become entangled.

IMPORTANT: The AR636 programming for this aircraft increases control sur­face movement when fl aps are fully down.

2. Move the entire aircraft as shown and ensure the control surfaces move in
the direction indicated in the graphic. If the control surfaces do not respond
as shown, do not fl y the aircraft. Refer to the receiver manual for more
information.

Once the AS3X system is active, control surfaces may move rapidly. This is
normal. AS3X remains active until the battery is disconnected.

In Flight Trimming

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

Flying Tips and Repairs

EN

3 Seconds

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 in position for takeoff (facing into the wind). Set your trans­mitter 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

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

Land the aircraft into the wind. Use high rate Elevator for landings. Use a small
amount of throttle for the entire descent. Lower the throttle to ¼ and fl ip your
fl aps switch to deploy the fl aps to the landing or “full down position”. Flaps

will make the landing approach steeper and slower, and allow for a
smoother landing. Flip your gear switch to lower your landing gear. This will

slow the aircraft further.

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.

WARNING:

Always decrease
throttle at propeller
strike.

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 (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.

• Offi cially designated AMA Air Show Teams (AST) are authorized to

use devices and practices as defi ned within the Team AMA
Program Document (AMA Document #718).
(j) Not operate a turbine-powered aircraft, unless in compliance with the
AMA turbine regulations. (AMA Document #510-A).

3. Model aircraft will not be fl own in AMA sanctioned events, air shows or

model demonstrations unless:
(a) The aircraft, control system and pilot skills have successfully
demonstrated all maneuvers intended or anticipated prior to the
specifi c event.
(b) An inexperienced pilot is assisted by an experienced pilot.

B. RADIO CONTROL

1. All pilots shall avoid fl ying directly over unprotected people, vessels,
vehicles or structures and shall avoid endangerment of life and property
of others.

2. A successful radio equipment ground-range check in accordance with
manufacturer’s recommendations will be completed before the fi rst fl ight
of a new or repaired model aircraft.

3. At all fl ying sites a safety line(s) must be established in front of which all
fl ying takes place (AMA Document #706.)
(a) Only personnel associated with fl ying the model aircraft are allowed at
or in front of the safety line.
(b) At air shows or demonstrations, a straight safety line must be
established.
(c) An area away from the safety line must be maintained for spectators.
(d) Intentional fl ying behind the safety line is prohibited.

4. RC model aircraft must use the radio-control frequencies currently allowed
by the Federal Communications Commission (FCC). Only individuals
properly licensed by the FCC are authorized to operate equipment on
Amateur Band frequencies.

5. RC model aircraft will not operate within three (3) miles of any pre-existing
fl ying site without a frequency-management agreement (AMA Documents
#922 and #923.)

6. With the exception of events fl own under offi cial AMA Competition

7. Under no circumstances may a pilot or other person touch a model aircraft
in fl ight while it is still under power, except to divert it from striking an
individual.

8. RC night fl ying requires a lighting system providing the pilot with a clear
view of the model’s attitude and orientation at all times. Hand-held illumi­ nation systems are inadequate for night fl ying operations.

9. The pilot of a RC model aircraft shall:
(a) Maintain control during the entire fl ight, maintaining visual contact
without enhancement other than by corrective lenses prescribed for
the pilot.
(b) Fly using the assistance of a camera or First-Person View (FPV) only
in accordance with the procedures outlined in AMA Document #550.
(C) Fly using the assistance of autopilot or stabilization system only in

Please see your local or regional modeling association’s guidelines for proper, safe
operation of your model aircraft.

4. When and where required by rule, helmets must be properly worn and

fastened. They must be OSHA, DOT, ANSI, SNELL or NOCSAE approved or
comply with comparable standards.
