Model Assembly

Wing Installation

1. Remove the canopy from the fuselage.

2. Turn the wing and fuselage so their bottom sides face up.

3. Place the wing’s aileron servo connectors (A) into the rectangular hole in

the fuselage.

4. Slide the two guide pins (B) of the wing into the two holes in the fuselage.

5. Align and attach the wing to the fuselage using a screw (C).

6. Inside the fuselage, connect both aileron servo connectors to the aileron
Y-harness. There is no difference between the two connections on a Y­harness. Left and right servo connectors do not have to be connected to a
particular side of a Y-harness.

7. When needed, disassemble in reverse order.

CAUTION: DO NOT crush or otherwise damage wiring when attaching
the wing to the fuselage.

Model Assembly Continued

Tail Installation

1. Place the model on its landing gear.

2. Turn the horizontal tail so the control horn faces down.

3. Slide the horizontal tail in the horizontal tail mount until it is centered
perpendicular to the vertical tail.

4. Apply 4 pieces of tape (A) on the fuselage mounts and the top and bottom
of the horizontal tail.

5. Attach the clevis to the elevator control horn (see instructions for
clevis connection).

6. When needed, disassemble in reverse order.

Landing Gear Installation

1. Turn the model so the bottom of the wing faces up.

2. Install the main landing gear by inserting the main gear struts (A) into the
corresponding gear plate hole located on each wing.

3. Carefully turn each strut in the gear plate until the horizontal section (B) of
the strut gently snaps into place.

4. Loosen the nose gear screw (C) in the nose gear arm before installing
the nose gear strut (D). The screw may be fully installed at the factory, so
loosen the screw enough to ensure the screw does not block the strut. A
hole in the cowling allows a screwdriver to be used to turn the screw on
the nose gear arm.

If more maneuvering space is needed, remove the propeller and cowling

from the model before installing the nose gear. (As shown in the “Service
of Power Components” section of this manual.)

5. Install the nose gear strut so the fl at surface of the strut faces forward. The
coil in the nose gear strut should face the rear of the airplane. Fully insert
the nose gear strut into the nose gear arm. When inserted, the top of the
strut will touch the upper portion of the fi rewall.

6. Fully tighten the nose gear screw against the fl at surface of the nose gear
strut.

7. When needed, disassemble in reverse order.

Always ensure the steering linkage clevis on the rudder servo arm is correctly
adjusted so the model steers straight when the rudder control is at neutral.

Clevis Installation

• Pull the tube from the clevis to the linkage.

• Carefully spread the clevis, then insert the clevis pin into the desired hole in
the control horn.

• Move the tube to hold the clevis on the control horn.

Control Surface Centering

After assembly and transmitter setup, confi rm that the control surfaces are
centered. If the control surfaces are not centered, mechanically center the
control surfaces by adjusting the linkages.

If adjustment is required, turn the clevis on the linkage to change the length of
the linkage between the servo arm and the control horn.

After binding a transmitter to the aircraft receiver, set the trims and
sub-trims to 0, then adjust the clevises to center the control surfaces.

Transmitter and Receiver Binding

Bind Plug Installation

BIND PLUG

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

™

DSM2®/DSMX® technology equipped aircraft

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.

Binding Procedure

IMPORTANT: The included AR610 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. 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 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

Battery Selection

We recommend the E-fl ite® 1800mAh 11.1V 3S 30C Li-Po battery
(EFLB18003S30). 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. Apply the loop side (soft side) of the hook and loop tape (A) to the bottom of

your battery.

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

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.

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

• The ESC will sound 3 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.

7. 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.

Control Direction Test

Elevator

Bind your aircraft and transmitter before performing these tests. Move the controls on the transmitter to ensure the aircraft control surfaces move correctly.
After doing the Control Test, correctly set the failsafe. Make sure the transmitter controls are at neutral and the throttle and throttle trim are in the low position,
then rebind the model to your transmitter. If the receiver loses its link to the transmitter, the failsafe automatically moves the controls and throttle settings to
those made at binding.

Flying Tips and Repairs

WARNING:

Always decrease
throttle at propeller
strike.

Post Flight

1

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.

6

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

7

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

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.

Takeoff

For your fi rst fl ights, set your transmitter timer or a stopwatch to 7 minutes.
Adjust your timer for longer or shorter fl ights once you have fl own the model.

Place the aircraft in position for takeoff (facing into the wind). Select low rates
for fi rst takeoff and gradually increase the throttle to 3/4 to full and steer with
the rudder. Pull back gently on the elevator and climb to a comfortable altitude.

Flying

Fly the airplane 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.

Landing

To land the aircaft, fl y the airplane down to about a foot above the ground.
Reduce power and add back pressure on the elevator to fl are the airplane.
Touch down with the main wheels fi rst by holding the nosewheel off the
ground. Avoid holding too much elevator after touchdown to prevent the plane
from becoming airborne again. Gently steer with the rudder until the plane has
slowed. Avoid sharp turns on the ground until the plane has slowed enough to
prevent scraping the wing tips.

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 (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). The hori-

zontal tail is not made of the same material, so use only foam-compatible
CA on the horizontal tail.

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.

AMA National Model Aircraft Safety Code

Effective January 1, 2014

A. GENERAL

A model aircraft is a non-human-carrying aircraft capable of sustained fl ight
in the atmosphere. It may not exceed limitations of this code and is intended
exclusively for sport, recreation, education and/or competition. All model fl ights
must be conducted in accordance with this safety code and any additional
rules specifi c to the fl ying site.

1. Model aircraft will not be fl own:

(a) In a careless or reckless manner.
(b) At a location where model aircraft activities are prohibited.

2. Model aircraft pilots will:

(a) Yield the right of way to all man carrying aircraft.
(b) See and avoid all aircraft and a spotter must be used when appropriate.
(AMA Document #540-D.)
(c) Not fl y higher than approximately 400 feet above ground level within
three (3) miles of an airport, without notifying the airport operator.
(d) Not interfere with operations and traffi c patterns at any airport, heliport
or seaplane base except where there is a mixed use agreement.
(e) Not exceed a takeoff weight, including fuel, of 55 pounds unless in
compliance with the AMA Large Model Aircraft program. (AMA
Document 520-A.)
(f) Ensure the aircraft is identifi ed with the name and address or AMA
number of the owner on the inside or affi xed to the outside of the
model aircraft. (This does not apply to model aircraft fl own indoors).
(g) Not operate aircraft with metal-blade propellers or with gaseous boosts
except for helicopters operated under the provisions of AMA Document
#555.
(h) Not operate model aircraft while under the infl uence of alcohol or while
using any drug which could adversely affect the pilot’s ability to safely
control the model.
(i) Not operate model aircraft carrying pyrotechnic devices which explode
or burn, or any device which propels a projectile or drops any object
that creates a hazard to persons or property.

Exceptions:

• Free Flight fuses or devices that burn producing smoke and are

securely attached to the model aircraft during fl ight.

• Rocket motors (using solid propellant) up to a G-series size may

be used provided they remain attached to the model during fl ight.
Model rockets may be fl own in accordance with the National
Model Rocketry Safety Code but may not be launched from
model aircraft.

• 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.

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.

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
Regulations, excluding takeoff and landing, no powered model may be
fl own outdoors closer than 25 feet to any individual, except for the pilot
and the pilot’s helper(s) located at the fl ight line.

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.

workmanship at the date of purchase.

What is Not Covered

This warranty is not transferable and does not cover (i) cosmetic damage, (ii)

Purchaser’s Remedy

Horizon’s sole obligation and purchaser’s sole and exclusive remedy shall be
that Horizon will, at its option, either (i) service, or (ii) replace, any Product

Questions, Assistance, and Services

Your local hobby store and/or place of purchase cannot provide warranty
support or service. Once assembly, setup or use of the Product has been
started, you must contact your local distributor or Horizon directly. This will
enable Horizon to better answer your questions and service you in the event
that you may need any assistance. For questions or assistance, please visit our
website at www.horizonhobby.com, submit a Product Support Inquiry, or call
the toll free telephone number referenced in the Warranty and Service Contact
Information section to speak with a Product Support representative.

country you live and use the Product in, please use the Horizon Online Service
Request submission process found on our website or call Horizon to obtain a
Return Merchandise Authorization (RMA) number. Pack the Product securely
using a shipping carton. Please note that original boxes may be included,
but are not designed to withstand the rigors of shipping without additional

protection. Ship via a carrier that provides tracking and insurance for lost or
damaged parcels, as Horizon is not responsible for merchandise until it arrives
and is accepted at our facility. An Online Service Request is available at http://

do not have internet access, please contact Horizon Product Support to obtain

offi ce.

Warranty Requirements
For Warranty consideration, you must include your original sales receipt
verifying the proof-of-purchase date. Provided warranty conditions have

been met, your Product will be serviced or replaced free of charge. Service or
replacement decisions are at the sole discretion of Horizon.

Non-Warranty Service
Should your service not be covered by warranty, service will be

completed and payment will be required without notifi cation or estimate
of the expense unless the expense exceeds 50% of the retail purchase
cost. By submitting the item for service you are agreeing to payment of the

service without notifi cation. Service estimates are available upon request. You
must include this request with your item submitted for service. Non-warranty
service estimates will be billed a minimum of ½ hour of labor. In addition you
will be billed for return freight. Horizon accepts money orders and cashier’s
checks, as well as Visa, MasterCard, American Express, and Discover cards.
By submitting any item to Horizon for service, you are agreeing to Horizon’s
Terms and Conditions found on our website http://www.horizonhobby.com/
content/_service-center_render-service-center.

ATTENTION: Horizon service is limited to Product compliant in the
country of use and ownership. If received, a non-compliant Product will
not be serviced. Further, the sender will be responsible for arranging
return shipment of the un-serviced Product, through a carrier of the
sender’s choice and at the sender’s expense. Horizon will hold non­compliant Product for a period of 60 days from notifi cation, after which it
will be discarded.
