Transmitter Setup
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 flights.
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 ights, you may adjust the expo
value to better suit your ying style.

Binding
Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identier)
code of a single specic 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.
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 ight 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 ight battery in the aircraft. The receiver LED will begin to ash 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 ights, power ON the transmitter for 5 seconds before connecting the ight battery.
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.

ESC/Receiver Arming, Battery Installation and Center of Gravity
EN
NOTICE: Always keep material or debris away
from the intake. When armed, the rotor will turn in
response to throttle movement and could ingest
loose objects.
The UMX A-10 requires a 3S 850mAh Li-Po battery
with an IC2 or EC2 connector (SPMX8503S30
recommended). Add a piece of hook and loop
material (hook side) to the side of the fuselage
along the battery compartment. Add a small piece
of hook and loop material (soft side) to the side of
the battery at the same end as the power lead. It is
important to only use a small piece to prevent the
battery from shifting. Using too large of a piece will
make it difcult to remove the battery and may lead
to fuselage damage.
Arming the ESC/receiver also occurs after binding
as previously described, but subsequent connection
of a ight battery requires the following steps.
1. Lower the throttle and throttle trim to the
lowest settings on your transmitter.
2. Remove the battery/canopy hatch from the
fuselage and install a flight battery (A) all the
way to the back of the battery comportment.
Center of Gravity (CG)
The CG location is 32-34mm back from the
leading edge of the wing at the root. Balance the
airplane inverted on this recommended CG mark
with all landing gear installed. Adjust as needed by
sliding the battery forward or back.
1

A
32-34mm
3. 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 successful connection is indicated by:
– A series of tones
– A continuous LED
CAUTION: Always disconnect the Li-Po
battery from the ESC when not ying 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 ying 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 re when batteries
are charged.

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, ip the Gear channel switch to position 0. Return the Gear switch to position 1 to
turn OFF SAFE Select and y with just the assistance of AS3X® technology.
If you become disoriented or the aircraft is in a confusing attitude, ip 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 ying, 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.

Control Centering
Before the first flights, or in the event of an
accident, make sure the flight 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. Ensure SAFE Select is OFF.
2. Make sure the control surfaces are neutral when
the transmitter controls and trims are centered.
The transmitter sub-trim must always be set
to 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
connector 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. Do not trim the
aircraft while SAFE Select is active. Always trim
the aircraft in AS3X mode. If the model requires
excessive 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.
EN
Factory Control Horn Settings
The illustration shows the factory settings for
linkages on the control horns. Linkage connections
on the control horns directly affect aircraft response.

Landing Gear Removal
The landing gear may be left installed or removed
to suit your ying area. We recommend using the
landing gear when you can take off and land from
a smooth surface. If you have long grass you may
choose to remove the landing gear, in which case you
will need to hand launch the aircraft and belly land.
1. Carefully pull the gear straight out of the
retainer clip that secures it into the fuselage.
When needed, assemble in reverse order.
When the landing gear is reinstalled, make sure the
nose gear is angled forward as shown.

Control Direction Test
EN
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.

Flying Tips and Repairs
Range Check your Radio System
After nal assembly, 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 moderate winds or inside in a very large indoor
facility. Always avoid ying near houses, trees, wires
and buildings. 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.
Wind
Fly in this area
600
feet (182.8 m)
Stand here
Hand Launching
Hold the aircraft above the wings between the
canopy and motor nacelles. Apply full throttle and
launch directly into the wind with an underhand
toss with the nose pointed up at approximately 45
degrees above the horizon.
Hold here from
the top for hand
launching
Tip: Electric ducted fan (EDF) aircraft require airspeed
for control and have less control authority at slow
speeds without a propeller slipstream moving air over
the control surfaces.
Takeoff
Taxi the aircraft in position for takeoff (facing into
the wind if ying outdoors). Gradually increase the
throttle to full power, holding a small amount of up
elevator and steering with the rudder. Climb gently
to check trim. Once the trim is adjusted, begin
exploring the ight envelope of the aircraft.
EN
Landing
Always land into the wind. Fly the landing pattern
with a slightly nose high attitude. Use throttle
management to control the decent rate of the
aircraft.
During are, 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 the main wheels or to belly land without
landing gear.
NOTICE: Always fully lower the throttle when landing
the aircraft to prevent intake of foreign objects, which
can damage the ducted fan 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, which
may require replacement.
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 rotor 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.
Low Voltage Cutoff (LVC)
LVC is a function built into your ESC to protect the
battery from over-discharge. When the battery
charge is low, LVC limits power supplied to the
motor. The aircraft will begin to slow and you
will hear the motor pulse. When the motor power
decreases, land the aircraft immediately and
recharge the ight battery.
NOTICE: Repeated ying to LVC will damage the
battery.
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.
For your first flights, set your transmitter timer
or a stopwatch to 5 minutes. Adjust your timer for
longer or shorter ights once you have own the
model.

EN
SAFE Select Flying Tips
When ying in SAFE Select mode the aircraft will return to level ight any time the aileron and elevator
controls are at neutral. Applying aileron or elevator control will cause the airplane to bank, climb or dive. The
amount the stick is moved will determine the attitude the airplane ies. Holding full control will push the
aircraft to the pre-determined bank and roll limits, but it will not go past those angles.
When ying with SAFE Select, it is normal to hold the control stick deected with moderate aileron input
when ying through a turn. To y smoothly with SAFE Select, avoid making frequent control changes and
don’t attempt to correct for minor deviations. Holding deliberate control inputs will command the aircraft to
y at a specic angle, and the model will make all corrections to maintain that ight attitude.
When ying with SAFE Select, throttle will make the aircraft climb or descend. Full throttle will cause the aircraft
to pitch up and climb slightly. Mid throttle will keep the airplane ying level. Low throttle will cause the airplane to
descend slightly nose-down.
Return the elevator and aileron controls to neutral before switching from SAFE Select mode to AS3X mode.
If you do not neutralize controls when switching into AS3X mode, the control inputs used for SAFE Select
mode will be excessive for AS3X mode and the aircraft will react immediately.

This section is generally accurate but does not take into account ight speed, battery charge status, and
other limiting factors.
