General Binding Tips and Failsafe, BNF
• The included receiver has been specically 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 ash rapidly when
the receiver enters bind mode.
Low Voltage Cutoff (LVC)
When a Li-Po battery is discharged below 3V per cell, it
will not hold a charge. The aircraft’s ESC protects the ight
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 immediately and replace or recharge the ight battery.
Always disconnect and remove the Li-Po battery from
the aircraft after each ight. Charge your Li-Po battery to
Install the Transmitter Batteries
1. Remove the battery cover.
2. Install the included four AA batteries, noting proper
polarity.
3. Reinstall the battery cover.
Low Battery Alarm
When the transmitter battery voltage drops below 4.7
volts, an alarm sounds and the voltage LEDs ash. Replace
the batteries immediately. If the alarm sounds while ying,
land your aircraft as soon as possible.
CAUTION: Do not attempt to recharge the
included AA batteries. These batteries are not
rechargeable. Charging non-rechargeable batteries may
cause the batteries to burst, resulting in injury to
persons and/or damage to property.

• 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 ofce.
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.

Transmitter Switches and LEDs
Bind/Panic Button: This button is used to control the Bind
and Panic Recovery Mode functions.
See the Binding section for information on re-binding
your transmitter and aircraft if necessary. The included
transmitter comes bound to the receiver/aircraft from the
factory, therefore binding is not typically necessary.
See the Sensor Assisted Flight Envelope (SAFE) Technology
section for information about Panic Recovery mode.
Hi/Lo Rate Switch: This switch supports high and low
rate functions on the elevator and aileron channels.
We recommend using low rates when rst learning to y or
for smooth and more precise maneuvering, and high rates
for more aggressive maneuvers and aerobatics.
In the upper, or “HI” position, servo travel is 100% on
these channels.
In the lower, or “LO,” position, servo travel decreases to 70%.
Flight Mode Switch: This switch is used to select the
SAFE ight mode. See the Sensor Assisted Flight Envelope
(SAFE) Technology section for information about the
various SAFE ight modes.
Throttle Cut Switch: This switch activates throttle cut.
With the throttle cut on (switch position 1), throttle input
from the throttle stick is deactivated. This safety feature
ensures any accidental bump of the throttle stick will not
activate the motor while the ight battery is connected.
With the throttle cut off (switch position 0), any position of
the throttle stick above the lowest setting will activate the
aircraft motor.
NOTICE: Always ensure the throttle stick is at the
lowest setting before switching the throttle cut function
off. Failure to do so will result in the motor activating.
LED and Audible Indications
Flashing with beeps: The transmitter is in bind mode,
because the bind button was held down while the
transmitter was powered on. See the Binding section for
more information.
Pulsates with one low tone beep every 2 seconds:
The transmitter battery voltage has dropped below 4.7
volts. Replace the transmitter batteries immediately. If this

Bind the Transmitter and Receiver
Binding is the process of programming the aircraft receiver with the identication code of the transmitter so the
receiver will only connect to that specic transmitter.
The included transmitter was bound to the aircraft at the
factory. If the aircraft does not respond to transmitter control
inputs when the batteries in the aircraft and transmitter are
fully charged, the aircraft receiver and transmitter may need
to be re-bound.
To re-bind the transmitter and receiver:
1. Power OFF the transmitter.
2. Set the throttle stick to the low position and all other
controls to neutral.* Ensure the aircraft is immobile.
IMPORTANT: The throttle will only arm if the transmitter
throttle control is at the lowest position.
3. Connect the ight battery to the ESC. The receiver will
cycle between DSMX and SLT approximately every
20 seconds. The receiver LED is visible with the wing
removed.
Transmitter LED Pattern

Control Surface Response
(viewed from the rear)
Control Centering
Before the rst ights, or in the event of an accident,
make sure the ight control surfaces are centered. Ad-
just the linkages mechanically if the control surfaces are
not centered, avoid excessive use of transmitter sub-trims.
Control surface centering must be done with SAFE off, and
AS3X not active. Keep the throttle at zero after powering
on to prevent AS3X from activating.
IMPORTANT: Enable throttle cut to help prevent accidental
throttle activation.
1. Verify the trims and subtrims on your transmitter are
neutral.
2. Connect a battery to the model with SAFE off and keep
throttle at zero.
3. When needed, use a pair of pliers to carefully bend the
metal linkage (see illustration).
4. 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 ight
trimmed position.
UMX Slow Ultra Stick

Control Horn Settings
The illustration shows the factory settings for the control
horns. Fly the aircraft at factory settings before making
changes.
After ying, 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.
Center of Gravity (CG)
The CG location is measured 43mm ± 3 behind the
leading edge of the wing. This CG location has been determined with the recommended 150mAh 1S 3.7V 50C Li-Po
battery (SPMX1501S50) installed to the front edge of the
battery tray. Adjust the battery forward or aft as needed to
achieve the proper CG location.
CAUTION: Install the battery but do not arm
the ESC while checking the CG. Personal injury
may result.

Flying Tips and Repairs
WARNING: Always engage throttle cut before
approaching the aircraft.
Range Check the Radio System
Range check the radio system with the aircraft. Refer to
your specic transmitter instruction manual for range test
information.
Flying
We recommend ying your aircraft outside in no greater
than a light breeze or inside in a large gymnasium. Always
avoid ying near houses, trees, wires and buildings. You
should also be careful to avoid ying in areas where there
are many people, such as busy parks, schoolyards or
soccer elds. Consult local laws and ordinances before
choosing a location to y your aircraft.
Takeoff
Place the aircraft in position for takeoff (facing into the
wind if ying outdoors). Set dual rates to low position and
gradually increase the throttle to ¾ to full and steer with
the aileron stick. Pull back gently on the elevator and climb
to check trim. Once the trim is adjusted, begin exploring
the ight envelope of the aircraft.
Landing
Always land into the wind. During the are, keep the wings
level and the aircraft pointed into the wind. Slowly lower
the throttle while easing back on the elevator to bring the
aircraft gently down on all three wheels.
NOTICE: Always fully lower the throttle at touch down
when landing the aircraft to prevent damage to the
propeller and motor.
Failure to lower the throttle stick and trim to the lowest
possible positions during a crash could result in damage to
the ESC in the receiver unit.
Over-Current Protection (OCP)
The aircraft is equipped with over-current protection. OCP
protects the ESC from overheating and stops the motor
when the transmitter throttle is set too high and the propeller cannot turn. OCP will only activate when the throttle
is positioned just above 1/2 throttle. After the ESC stops
the motor, fully lower the throttle to re-arm the ESC.
Repairs
Crash damage is not covered under warranty.
Repair this aircraft using foam-compatible CA glue or clear
tape. Only use foam-compatible CA glue as other types of
glue can damage the foam. When parts are not repairable,
see the Replacement Parts List for ordering by item number.

the 2018 FAA Reauthorization Bill. This free test is required
by the FAA for all recreational flyers in the United States. The
completed certificate must be presented upon request by any
FAA or law enforcement official.
If your model aircraft weighs more than .55lbs or 250 grams,
you are required by the FAA to register as a recreational flyer
and apply your registration number to the outside of your
aircraft. To learn more about registering with the FAA, use the

AMA National Model Aircraft Safety Code
Effective January 1, 2018
A model aircraft is a non-human-carrying device capable of sustained flight within visual line of sight of the pilot or spotter(s). It
may not exceed limitations of this code and is intended exclusively for sport, recreation, education and/or competition. All model
flights must be conducted in accordance with this safety code and related AMA guidelines, any additional rules specific to the
flying site, as well as all applicable laws and regulations.
As an AMA member I agree:
• I will not fly a model aircraft in a careless or reckless
manner.
• I will not interfere with and will yield the right of way to all
human-carrying aircraft using AMA’s See and Avoid Guidance and a spotter when appropriate.
• I will not operate any model aircraft while I am under the
influence of alcohol or any drug that could adversely affect
my ability to safely control the model.
• I will avoid flying directly over unprotected people, moving
vehicles, and occupied structures.
• I will fly Free Flight (FF) and Control Line (CL) models in
compliance with AMA’s safety programming.
• I will maintain visual contact of an RC model aircraft without
enhancement other than corrective lenses prescribed to
me. When using an advanced flight system, such as an
autopilot, or flying First-Person View (FPV), I will comply
with AMA’s Advanced Flight System programming.
• I will only fly models weighing more than 55 pounds,
including fuel, if certified through AMA’s Large Model
Airplane Program.
• I will only fly a turbine-powered model aircraft in compliance with AMA’s Gas Turbine Program.
• I will not fly a powered model outdoors closer than 25 feet
to any individual, except for myself or my helper(s) located
at the flightline, unless I am taking off and landing, or as
otherwise provided in AMA’s Competition Regulation.
• I will use an established safety line to separate all model
aircraft operations from spectators and bystanders.
