X 5
100%
100%
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 elevator and rudder stick 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 propeller 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.
Binding
CAUTION: Always keep hands away from the propeller. When armed, the motor will turn the propeller in
response to any throttle movement.
Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single
specific transmitter.
Binding Procedure
1. Refer to your transmitter’s unique instructions for
binding to a receiver.
2. Ensure the transmitter throttle stick is in the lowest
position.
3. Install and connect a fully charged flight battery to the
aircraft.
4. After approximately 5 seconds, the LED on the aircraft
flight control board will begin to flash rapidly.
5. Put your transmitter into bind mode.
6. The LED on the aircraft flight control board will glow
solid when binding is complete.

Control Surface Centering
Control Direction Test
Stick Movement Control Surface Reaction
Before your first flights, or in the event of a crash, check
to make sure the flight control surfaces are centered. It is
much better to do this mechanically due to the mechanical
limits of linear servos.
1. Make sure the transmitter trims are centered, and
sub-trims are set to 0.
2. Check to see if any of the flight control surfaces are
not centered.
3. If the surface is not centered, use a pair of pliers and
carefully lengthen or shorten the pushrod by adjusting
the U-shape in the pushrod.
If at any time during the test the controls respond in the
opposite direction of operation of the flight controls, follow
your transmitter’s instructions to reverse the flight controls.
CAUTION: Always keep hands away from the
propeller. When armed, the motor will turn the
propeller in response to any throttle movement.
Test the controls prior to the first flight to ensure none
of the servos, linkages or parts were damaged during
shipping and handling and the controls function in the
correct directions.
Move the rudder stick to the right. The rudder should
move to the right. This will cause the aircraft to yaw and
bank to the right in flight.
Move the rudder stick to the left. The rudder should move
to the left. This will cause the aircraft to yaw and bank to
the left in flight.
Pull the elevator stick backward. The elevator should
move up. This will cause the nose of the aircraft to pitch
up in flight.
Push the elevator stick forward. The elevator should move
down. This will cause the nose of the aircraft to pitch
down in flight.

22-28mm
AS3X Control Response Test
This test ensures that the AS3X control system is
functioning properly. Assemble the aircraft and bind your
transmitter to the receiver before performing this test.
1. Raise the throttle to any setting above 25%, then
lower the throttle to activate AS3X technology.
CAUTION: Keep all body parts, hair and loose
clothing away from the propeller, as these items
could become entangled.
2. 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 remains active until the
battery is disconnected.
Aircraft movement AS3X Reaction
PitchYaw
Center of Gravity
The CG location is 25mm back from the leading edge
at the wing root. This has been determined with the
recommended 1S 150mAh 3.7V Li-Po battery installed in
the middle of the battery cavity.

Trimming the Aircraft
Flying
Consult local laws and ordinances before choosing a
location to fly your aircraft.
WARNING: The motor will become hot during normal
use. Do not touch the motor until it has cooled.
We recommend flying your aircraft outside in no greater
than 10mph winds or inside in a large gymnasium. Always
avoid flying near houses, trees, wires and buildings.
Avoid flying in areas where there are many people, such as
busy parks, schoolyards or soccer fields.
Set a timer for 7 minutes.
Hand Launching
To hand launch the aircraft, hold the fuselage under the wings.
Advance to full throttle and give the aircraft a firm throw,
slightly up (5–10 degrees above the horizon), and directly into
the wind. After the model gains altitude and speed, decrease
the throttle and trim the aircraft for level flight
when in AS3X flight mode.
Landing
Always land into the wind. Reduce throttle to zero and
allow the aircraft to settle into a glide path. During landing
approach keep the wings level and the aircraft pointed into
the wind. As the aircraft settles close to the ground, ease
back on the elevator to flare for landing.
NOTICE: Always fully lower the throttle at touch down
when landing the aircraft. 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 or to the propeller shaft.
Crash damage is not covered under warranty.
Repairs
Repair this aircraft using foam safe CA glue or clear tape.
When parts are not repairable, see the Replacement Parts
List for ordering by item number.
Direction of Drift Trim to Correct
Adjusting Trim in Flight
Familiarize yourself with your transmitter’s controls and
the aircraft’s response before flying by performing the
recommended Control Direction Test. Press the trim buttons
on your transmitter to adjust how the aircraft flies.
If the aircraft’s nose drifts in flight while the sticks are at
neutral (centered) and the throttle is at 50% in AS3X flight
mode, adjust the trim to compensate:
• Up trim to stop down drift
• Down trim to stop up drift
• Left trim to stop right drift and roll
• Right trim to stop left drift and roll
If you press a trim button until no beep sounds and the
aircraft does not fly straight and level in no wind, land and
manually adjust the trim as described below.
Manually Adjusting Trim
Only adjust trims in AS3X flight mode. Power on the model,
carefully hold the aircraft and advance the throttle for prop
to spin. Lower throttle to 0% and manually adjust trims if
needed.
Press the trim buttons to return to center (3 beeps will sound),
then use a pair of pliers to carefully adjust the metal U-bend on
the control rod of the surface requiring adjustment:
• Adjust the U-bend smaller for up elevator or right rudder.
• Widen the U-bend for down elevator or left rudder.

Removing the Top of the Fuselage
To access the inside of the fuselage:
1. Remove the two screws holding the wing and slide the
wing out of the fuselage.
2. Use a fresh hobby knife to cut the tape holding the top
and bottom of the fuselage together.
Replacing the Propeller
WARNING: The motor will become hot during normal
use. Do not touch the motor until it has cooled.
To remove/replace the propeller:
1. Use needle-nose pliers or hemostats to grip the
propeller shaft to keep it from turning.
2. Spin the propeller counterclockwise to remove the old
propeller.
3. Thread the new propeller and spinner clockwise onto
the propeller shaft until snug. Do not overtighten the
propeller on the shaft.
Replacing the Propeller Shaft
WARNING: The motor will become hot during normal
use. Do not touch the motor until it has cooled.
IMPORTANT: The rear of the propeller shaft and nylon
nut are reverse-threaded.
To replace the propeller shaft:
1. Gently grasp the white nylon nut located at the back of
the propeller shaft using needle-nose pliers or hemostats.
2. While holding the nylon nut, rotate the spur gear
clockwise. The prop shaft will thread out of the nut.
3. Gently pull on the spur gear to slide the propeller shaft
out of the gearbox.
4. Thread the propeller and spinner onto the new
propeller shaft by holding the spur gear and turning
the prop clockwise.
5. Slide the new propeller shaft into the gearbox.
