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.

To obtain the best flight performance, we recommend
using a DSM2®/DSMX®transmitter capable of Dual Rates.
Before binding, ensure that you are starting with a blank
acro model in your transmitter.
IMPORTANT: After you set up your model, always rebind
the transmitter and receiver to set the desired failsafe
positions.
Program Your Transmitter
1. Start with a new ACRO Model.
2. Set Aircraft Type: Wing >1Ail 1Flap
: Tail > Normal
3. Leave all settings at their default values.
The Gear Switch (Ch 5) will control the SAFE mode func-
tion.
• Switch position 0 = SAFE Mode
• Switch position 1 = AS3X Mode
Transmitter Setup
Dual Rates and Expos
The suggested settings shown here are the recommended
starting settings. Adjust according to the individual prefer-
ences after the initial flight.
NOTICE: Do not set your transmitter travel adjust
over 100%. If the TRAVEL ADJUST is set over 100%,
it will not result in more control movement, it will
overdrive the servo and cause damage.
It is normal for linear servos to make significant noise. The
noise is not an indication of a faulty servo.
TIP: For the first flight, fly the model in low rate.
TIP: When not using the flaperon function, only fly in flap
position 0, as Positions 1 and 2 will affect elevator trim.

The UMX Timber X includes a flaperon option. Activate it
using transmitter stick and switch movements.
The ailerons function normally from the factory, respond-
ing to aileron input from the transmitter.
To control the ailerons as flaps, activate the flaperon
option. Once activated, use the Flap System menu in the
transmitter to command the ailerons down together, acting
as flaps.
Additionally, the ailerons can move up together, acting
as spoilers. The flaperons continue to respond to aileron
commands for roll control while they move down or up for
flaps/spoilers.
Engage the flaperon feature using these steps:
1. Power ON the transmitter.
2. Power ON the aircraft.
3. Hold both transmitter sticks in opposite corners to
command low throttle, left rudder, down elevator, and
right aileron.
4. Toggle the gear switch (CH5) 5 times (1 toggle=full
up and down). The control surfaces move, as this is
alternately selecting AS3X and SAFE modes. You will
notice a change in the movement pattern as flaperon is
turned ON or OFF.
5. Repeat this process to turn flaperon functionality ON
or OFF.
Advanced Setup
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 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.

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
is increased over 25% 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. Install the flight battery in the center of the battery tray.
Ensure the battery is secured by the hook and loop
strip.
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-ite 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.

Control Surface Direction
Switch on the transmitter and connect the
battery. Use the transmitter to operate the
aileron, elevator, and rudder controls. View the
aircraft from the rear when checking the control
directions.
NOTICE: Bind the aircraft and transmitter
before performing these tests. Move the
transmitter controls to make sure the aircraft
control surfaces move correctly and in the
proper direction. Make sure the tail linkages
move freely.
Ailerons
1. Move the aileron stick to the left. The left
aileron should move up and the right aileron
should move down, which will cause the
aircraft to bank left.
2. Move the aileron stick to the right. The right
aileron should move up and the left aileron
down, which will cause the aircraft to bank
right.
Elevators
3. Pull the elevator stick back. The elevator
should move up, which will cause the aircraft
to pitch up.
4. Push the elevator stick forward. The elevator
should move down, which will cause the
aircraft to pitch down.
Rudder
5. Move the rudder stick to the left. The rudder
should move to the left, which will cause the
aircraft to yaw left.
6. Move the rudder stick to the right. The
rudder should move to the right, which will
cause the aircraft to yaw right.

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.
ElevatorAileronRudder
This test ensures that the AS3X®control system is functioning properly. The AS3X system in your UMX Timber X is an
advanced stabilization system, and the aircraft must remain stationary during initialization.
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. Remove the ball link connector from the control horn.
3. Adjust the plastic ball link by screwing it in or out, then
reassemble it on the control horn.
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
AS3X®Control Response Test BNF
Measure neutral elevator position at the elevator counter-
balance, 1mm above the horizontal stabilizer (slight down
elevator, see the image below). This will vary slightly,
depending upon battery choice and CG preference.

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.
Post Flight Checklist

1. Disconnect the flight battery from the ESC
(Required for safety and battery life).
2. Power OFF the transmitter.
3. Remove the flight battery from the aircraft.

4. Store the flight battery apart from the aircraft.
5. Make note of the flight conditions and flight
plan results, planning for future flights.
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.
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.
