Thank you for purchasing the E-fl ite® UMX™ Sbach® 342 3D. Designed by world-class competition pilot and
designer Mike McConville, this 4-channel, scale aerobatic monoplane is going to thrill you, especially if your
interest is fl ying extreme precision aerobatics and 3D maneuvers in a park or a large backyard. Its 2S Li-Po,
2500Kv brushless power system is one of the most powerful ever developed for an aircraft this small. And
although its phenomenal power-to-weight ratio is a big reason the UMX Sbach 342 3D fl ies better than a
typical ultra micro, what will truly be amazing is how much the UMX Sbach 342 3D performs like an expertly
tuned giant-scale airplane. Thanks to its AS3X
fl ying precision aerobatic and 3D maneuvers with a greatly amplifi ed sense of authority and stability, even in
moderately windy conditions.
The exceptional capabilities of the UMX Sbach 342 3D may require a little more fi rst-fl ight preparation than
you may be used to with other Bind-N-Fly
carefully so that you are equipped to successfully enjoy all the benefi ts this outstanding ultra micro model
has to offer.

AS3X Stabilization Delivers Breakthrough Performance
Horizon Hobby has always made RC sport, scale
and unique aircraft with the kind of performance
experts appreciate. Now the exclusive Artificial
Stability – 3 aXis (AS3X) system helps take
performance expectations in ultra micro aircraft a
quantum leap higher.
Based on the successful use of MEMS sensor
technology within the AS3X Stabilization System
essential to Blade
helicopters, the specifically tuned AS3X System
for airplanes helps invisibly correct for turbulence,
torque and tip stalls when encountered.
®
ultra micro flybarless
Furthermore, the outstanding control agility delivers
an ultra smooth, locked-in feel that obeys your
every command with performance that’s natural
feeling. It’s so gratifying, in fact, that it’s as though
you’re the RC pilot of an expertly tuned,
giant-scale aircraft.
AS3X will change the way you’ll want to fly now and
in the future. To see what we mean, go to
www.E-fliteRC.com/AS3X.
Prefl ight Checklist
1. Charge fl ight battery.
2. Install fl ight battery in the aircraft
(once it has been fully charged).
3. Bind aircraft to your transmitter.
4. Make sure linkages move freely.
5. Perform Control Direction Test with
the transmitter.
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 fl ight battery from over-discharge using
Low Voltage Cutoff (LVC). Before the battery charge
decreases too much, LVC removes power supplied
to the motor. Power to the motor quickly decreases
and increases, showing that some battery power is
reserved for fl ight control and safe landing.
When the motor power pulses, land the aircraft
immediately and recharge the fl ight battery.
Disconnect and remove the Li-Po battery from the
aircraft after use to prevent trickle discharge. Fully
charge your Li-Po battery before storing it. During

7. Adjust center of gravity.
8. Perform a radio system Range
Check.
9. Find a safe and open area.
10. Plan fl ight for fl ying fi eld conditions.
storage, make sure battery charge does not fall
below 3V per cell.
Tip: Due to the quiet nature of the aircraft, you may
not hear the pulsing of the motor.
For your fi rst fl ights, set your transmitter timer or a
stopwatch to 5 minutes. Adjust your timer for longer
or shorter fl ights once you have fl own the aircraft.
Flights of 6 minutes or more are achievable if using
proper throttle management.
NOTICE: Repeated fl ying to LVC will damage
the battery.

Transmitter and Receiver Binding
Binding is the process of programming the receiver of the control unit to recognize the GUID (Globally
Unique Identifi er) code of a single specifi c transmitter. You need to ‘bind’ your chosen SpektrumTM DSM2
®
DSMX
technology equipped aircraft transmitter to the receiver for proper operation.
Any JR® or Spektrum DSM2/DSMX transmitter can bind to the SPMAS6410NBL receiver. Due to the aerobatic
capabilities of the UMX Sbach 3D, it is highly recommended that you use a transmitter with dual rates. Please
visit www.bindnfl y.com for a complete list of compatible transmitters.
CAUTION: When using a Futaba transmitter with a Spektrum DSM module, you must reverse the
throttle channel and rebind. Refer to your Spektrum module manual for binding and failsafe instructions.
Refer to your Futaba transmitter manual for instructions on reversing the throttle channel.
Binding Procedure
1. Refer to your transmitter’s unique instructions for binding to a receiver.
2. Make sure the fl ight battery is disconnected from the aircraft.
3. Power off your transmitter.
4. Connect the fl ight battery in the aircraft. The receiver LED will begin to fl ash rapidly (typically after 5 seconds).
5. Make sure transmitter controls are neutral and throttle and throttle trim are in low position.
6. Put your transmitter into bind mode. Refer to your transmitter’s manual for binding button or switch instructions.
7. After 5 to 10 seconds, the receiver status LED will become 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 fl ights, power on the transmitter for 5 seconds before connecting the fl ight battery.

Installing the Flight Battery
1. Remove the battery hatch from the nose of the
aircraft and power on your transmitter.
2. Attach the flight battery to the hook and loop
strip (A) on the battery tray. See the Adjusting
the Center of Gravity instructions to determine
the battery position for your desired
flying style.
3. Place the aircraft on the ground out of the
wind and connect a fully charged
flight battery.
Ensure the aircraft is immobile for 5 seconds
so the AS3X system initializes correctly. See
the Arming the ESC instructions for correct
connection of the battery to the ESC.
4. Install the battery hatch.
NOTICE: If using a different battery than the
recommended 2-Cell 7.4V 180mAh 20C Li-Po, you
will need to apply a circle of hook and loop fastener
to the back of the battery, opposite the side with
the label, in order to hold the battery in place.
CAUTION: Always disconnect the Li-Po
battery from the aircraft receiver when not fl 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 fi re when
batteries are charged.

Arming the ESC
Arming the ESC also occurs after binding as previously described, but subsequent connection of a fl ight
battery requires the steps below.
1 2
Lower throttle and throttle
trim to lowest settings.
Power on the Transmitter,
then wait 5 seconds.
If you accidentally connect the battery while the throttle is fully raised, the ESC will enter programming
mode. Disconnect the battery immediately.
The AS3X system will not activate until the throttle stick or trim is increased for the fi rst time. Once the AS3X
is active, the control surfaces may move rapidly on the aircraft. This is normal.
AS3X will remain active until the battery is disconnected.
CAUTION: Always keep hands away from the propeller. When armed, the motor will turn the propeller
in response to any throttle movement.
Install the fl ight battery and
connect it to the ESC.

Keep the aircraft
immobile on its wheels away
from wind for fi ve seconds.

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 all linkages move freely and that paint or decals are not adhered to them.
Control Centering
Before the fi rst fl ights, or in the event of an
accident, make sure the fl 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
centered. 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
connector shorter. Make the U-shape wider
to make the linkage longer.
6
Centering Controls After First Flights
For best performance with AS3X, it is important
that excessive trim is not used. If the aircraft re-
quires 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 fl ight
trimmed position.
