General Binding Tips and Failsafe BNF
• The included receiver has been specifically programmed
for operation of this aircraft. Refer to the receiver manual
for correct setup if the receiver is replaced.
• Keep away from large metal objects while binding.
• Do not point the transmitter’s antenna directly at the
receiver while binding.
• The orange LED on the receiver will flash rapidly when
the receiver enters bind mode.
• Once bound, the receiver will retain its bind settings for
that transmitter until you re-bind.
• If the receiver loses transmitter communication, the
failsafe will activate. Failsafe moves the throttle channel
to low throttle. Pitch and roll channels move to actively
stabilize the aircraft in a descending turn.
• If problems occur, refer to the troubleshooting guide or if
needed, contact the appropriate Horizon Product Support
office.

When a Li-Po battery is discharged below 3V per cell, it
will not hold a charge. The aircraft’s ESC protects the flight
battery from over-discharge using Low Voltage Cutoff
(LVC). Once the battery discharges to 3V per cell, the
LVC will reduce the power to the motor in order to leave
adequate power to the receiver and servos to land the
airplane.
When the motor power decreases, land the aircraft im-
mediately and replace or recharge the flight battery.
Always disconnect and remove the Li-Po battery from
the aircraft after each flight. Charge your Li-Po battery to
about half capacity before storage. Make sure the battery
charge does not fall below 3V per cell. Failure to unplug a
connected battery will result in trickle discharge.
For your first flights, set your transmitter timer or a stop-
watch to 5 minutes. Adjust your timer for longer or shorter
flights once you have flown the model.
NOTICE: Repeated flying to LVC will damage the battery.
Low Voltage Cutoff (LVC)
Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single
specific transmitter. You need to ‘bind’ your chosen Spektrum™DSM2/DSMX technology equipped aircraft transmitter to
the receiver for proper operation.
Any full range Spektrum DSM2/DSMX transmitter can bind to the DSM2/DSMX receiver.
Transmitter and Receiver Binding
Binding Procedure
1. Refer to your transmitter’s unique instructions for binding to a receiver (location of transmitter’s Bind control).
2. Make sure the flight battery is disconnected from the aircraft.
3. Power off your transmitter.
4. Place the aircraft on a level surface away from wind.
5. Connect the flight battery in the aircraft. The receiver LED will begin to flash rapidly (typically after 5 seconds).
6. Make sure the transmitter controls are neutral and the throttle and throttle trim are in low position.
7. Put your transmitter into bind mode. Refer to your transmitter’s manual for binding button or switch
instructions.
8. After 5 to 10 seconds, the receiver status LED will turn solid, indicating that the receiver is bound to the
transmitter. If the LED does not turn solid, refer to the Troubleshooting Guide at the back of the manual.
For subsequent flights, power ON the transmitter for 5 seconds before connecting the flight battery.
IMPORTANT: After you set up your model, always rebind
the transmitter and receiver to set the desired failsafe
positions.
If your transmitter allows it, enable the throttle cut feature.
Always engage throttle cut before approaching the aircraft.
Dual Rates
Low rate is recommended for the initial ights.
NOTICE: To ensure AS3X®technology functions properly,
do not lower rate values below 50%.
NOTICE: If oscillation occurs at high speed, refer to the
Troubleshooting Guide for more information.
Exponential
After your initial flights, you may adjust the expo value to
better suit your flying style.

Integrated Telemetry
This aircraft includes telemetry between the ESC and
receiver, which can provide information including; RPM,
voltage, motor current, throttle setting (%), FET (speed
controller) temperature, and BEC (servo power supply)
temperature.
To View Telemetry
1. Begin with the transmitter bound to the receiver.
2. Power on the transmitter.
3. Power on the aircraft.
4. A signal bar appears in the top left corner of the screen
when the telemetry information is being received.
5. Scroll past the servo monitor to view the technology
screens.
For more information about compatible transmitters, firm-
ware updates, and how to use the telemetry technology on
your transmitter, visit www.SpektrumRC.com.
SAFE®Select Technology
When SAFE Select is activated, bank and pitch limitations
keep you from over-controlling the aircraft. Additionally,
by releasing the controls in the event you lose orientation,
SAFE Select will keep the aircraft level.
To activate SAFE®Select, flip the Gear channel switch to
position 0. Return the Gear switch to position 1 to turn
OFF SAFE Select and fly with just the assistance of AS3X®
technology.
If you become disoriented or the aircraft is in a confusing
attitude, flip the Gear switch to position 0 and release the
sticks. With the aileron, elevator and rudder sticks in the
neutral position, SAFE Select will automatically keep the
airplane in a straight and level attitude.
Disabling and Enabling SAFE Select
By default, the SAFE Select function of your UMX aircraft is
enabled and assigned to the Gear channel switch (channel
5). If you do not wish to have access to SAFE Select while
flying, you can choose to disable SAFE Select functionality.
AS3X will still be active when SAFE Select is disabled.
IMPORTANT: Before attempting to disable or enable SAFE
Select, ensure the aileron, elevator, rudder, throttle and
gear channels are all on high rate with the travel set to
100%. Turn throttle hold OFF if it is programmed in the
transmitter.
CAUTION: Keep all body parts clear of the rotor,
intake and exhaust tube and keep the aircraft
securely restrained in case of accidental throttle
activation.
1. Power on the transmitter.
2. Power on the aircraft.
3. Hold both transmitter sticks to the inside bottom
corners and toggle the Gear switch 5 times
(1 toggle = full up and down). The control surfaces of
the aircraft will move, indicating SAFE Select has been
enabled or disabled.
Repeat the process again to re-enable or disable SAFE
Select.
DX4e, DX5e, DXe, and DXS Transmitters
The Gear switch is the FMODE switch on the these
transmitters, and the switch needs to be toggled between
position 0 and 2 when disabling/enabling SAFE Select.

ESC/Receiver Arming, Battery Installation and Center of Gravity
CAUTION: Always keep hands away from the
propeller. When armed, the motor will turn the
propeller in response to any throttle movement.
Arming the ESC/receiver also occurs after binding as
previously described, but subsequent connection of a flight
battery requires the following steps.
AS3X
The AS3X®system will not activate until the throttle
stick or trim is increased for the first time. Once active,
the control surfaces may move rapidly and noisily on the
aircraft. This is normal. AS3X technology will remain active
until the battery is disconnected.
1. Remove the battery hatch from the fuselage.
2. Attach the battery to the hook and loop strip so the
battery is against the motor mount.
Center of Gravity (CG)
At the wing root, measure the CG location 32mm back
from the leading edge of the wing at the center section.
3. Lower the throttle and throttle trim to the lowest set-
tings on your transmitter. Power on your transmitter,
then wait 5 seconds.
4. Connect the battery to the ESC, noting proper polarity.
Keep the plane immobile and away from wind for 5
seconds to allow the AS3X system to initialize. A series
of tones and a continuous LED indicates a successful
connection.
Spektrum or E-flite 2S batteries with a PH plug require
an adapter lead. (SPMXCA327).
CAUTION: Always disconnect the Li-Po battery
from the ESC when not flying to eliminate power
supplied to the motor. The ESC does not have an
arming switch and will respond to any transmitter input
when a signal is present.
CAUTION: Always disconnect the Li-Po battery
from the ESC when not flying to avoid
over-discharging the battery. Batteries discharged to a
voltage lower than the lowest approved voltage may
become damaged, resulting in loss of performance and
potential fire when batteries are charged.

Before the rst ights, or in the event of an accident,
make sure the ight control surfaces are centered.
Adjust the linkages mechanically if the control surfaces
are not centered. Use of the transmitter sub-trims may not
correctly center the aircraft control surfaces due to the
mechanical limits of linear servos.
1. Make sure the control surfaces are neutral when
the transmitter controls and trims are entered. The
transmitter sub-trim must always be set to zero.
2. When needed, use a pair of pliers to carefully bend the
metal linkage (see illustration).
3. Make the U-shape narrower to make the linkage
shorter. Make the U-shape wider to make the linkage
longer.
Centering Controls After First Flights
For best performance with AS3X, it is important that
excessive trim is not used. If the aircraft requires exces-
sive transmitter trim (4 or more clicks of trim per channel),
return the transmitter trim to zero and adjust the linkages
mechanically so that the control surfaces are in the flight
trimmed position.
Control Centering
Aircraft Movement AS3X Reaction
1. Advance the throttle above 25%
to activate the AS3X system.
2. Fully lower the throttle.
3. 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 fly 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 is active until
the battery is disconnected.

Control Direction Tests
Traditional Control Direction Test
You should bind your aircraft and transmitter before doing these tests. Move the controls on the transmitter to make sure
the aircraft control surfaces move correctly and in the proper direction. Make sure the tail linkages move freely and that
paint or decals are not adhered to them.
AS3X®Control Direction Test
This test ensures that the AS3X®control system is functioning properly.

We recommend flying your aircraft outside in calm condi-
tions. Always avoid flying near houses, trees, wires and
buildings. You should also be careful to avoid flying in
areas where there are many people, such as busy parks,
schoolyards or soccer fields. Consult local laws and ordi-
nances before choosing a location to fly your aircraft.
Takeoff
Place the aircraft in position for takeoff (facing into the
wind if flying outdoors). Set dual rates to low position and
gradually increase the throttle to ¾ to full and steer with
the rudder. Pull back gently on the elevator and climb to
check trim. Once the trim is adjusted, begin exploring the
flight envelope of the aircraft.
Landing
Land into the wind. This is very important for this model.
Fly the aircraft to approximately 6 inches (15cm) 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 flare. During flare, keep
the wings level and the airplane
pointed into the wind. Gently lower
the throttle while pulling back on the
elevator to bring the aircraft down
on all three wheels.
Failure to lower the throttle stick and
trim to the lowest possible positions
during a crash could result in dam-
age to the ESC in the receiver unit,
which may require replacement.
This aircraft is equipped with Over Current Protection
(OCP). This feature protects the ESC from overheating.
OCP stops the motor when the transmitter throttle is set
too high and the propeller cannot turn. The OCP will only
activate when the throttle stick is positioned just above
1/2 throttle. After the ESC stops the motor, fully lower the
throttle to re-arm the ESC.
NOTICE: Crash damage is not covered under the war-
ranty.
Repairs
Repair the aircraft using foam-compatible CA (cyanoacry-
late adhesive) or clear tape. Only use foam-compatible
CA, as other types of glue can damage the foam. 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 foam-compatible CA accelerant on your
aircraft can damage paint. DO NOT handle the aircraft
until the accelerant fully dries.
NOTICE: When you are finished flying, never leave the
aircraft in direct sunlight or in a hot, enclosed area such
as a car. Doing so can damage the foam.
Flying Tips and Repairs
Always
decrease throttle at
propeller strike.
CAUTION
Control Horn Settings
The illustration shows the factory settings for the control
horns. Fly the aircraft at factory settings before making
changes.
After flying, you may choose to adjust the linkage positions
for the desired control response.
CAUTION: When these are incorrectly connected
for the pilot’s skill level, unexpected aircraft
response to controls can result. This can cause damage
to the aircraft and personal injury.

NEGLIGENCE, STRICT LIABILITY OR ANY OTHER THEORY OF
LIABILITY, EVEN IF HORIZON HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES. Further, in no event shall the
liability of Horizon exceed the individual price of the Product on
which liability is asserted. As Horizon has no control over use,
setup, final assembly, modification or misuse, no liability shall
be assumed nor accepted for any resulting damage or injury.
By the act of use, setup or assembly, the user accepts all re-
sulting liability. If you as the purchaser or user are not prepared
to accept the liability associated with the use of the Product,
purchaser is advised to return the Product immediately in new
and unused condition to the place of purchase.
Law—These terms are governed by Illinois law (without
regard to conflict of law principals). This warranty gives you
specific legal rights, and you may also have other rights which
vary from state to state. Horizon reserves the right to change or
modify this warranty at any time without notice.
WARRANTY SERVICES
Questions, Assistance, and Services—Your local hobby
store and/or place of purchase cannot provide warranty sup-
port 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.

inspected or serviced and is compliant in the 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 insur-
ance for lost or damaged parcels, as Horizon is not responsible
for merchandise until it arrives and is accepted at our facility.

hobby.com/content/service-center_render-service-center. If
you do not have internet access, please contact Horizon Prod-
uct Support to obtain a RMA number along with instructions for

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.

by warranty, service will be completed and payment will be
required without notification 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 notification. 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
