around your model to avoid collisions or injury.
This model is controlled by a radio signal subject
to interference from many sources outside your
control. Interference can cause momentary loss
of control.
• Always operate your model in open spaces away
from full-size vehicles, traffi c and people.
• Always carefully follow the directions and
warnings for this and any optional support equipment (chargers, rechargeable battery packs, etc.).
• Always keep all chemicals, small parts and
anything electrical out of the reach of children.
• Always avoid water exposure to all equipment
not specifi cally designed and protected for this
purpose. Moisture causes damage to electronics.
• Never place any portion of the model in your
mouth as it could cause serious injury or
even death.

• Never operate your model with low transmitter
batteries.
• Always keep aircraft in sight and under control.
• Always use fully charged batteries.
• Always keep the transmitter powered on while
aircraft is powered.
• Always remove batteries before disassembly.
• Always keep moving parts clean.
• Always keep parts dry.
• Always let parts cool after use before touching.

• Always ensure failsafe is properly set
before fl ying.
• Never operate aircraft with damaged wiring.
• Never touch moving parts.
hank you for purchasing the E-fl ite® UMX™ Pitts® S-1S ultra micro airplane. Despite its size, this model
T
has been engineered to deliver a potent scale model that handles great. Molded lightweight foam
construction makes it possible for the high-output brushless power system installed to provide quick
acceleration and strong vertical climbs. Four performance linear long-throw servos provide precision
control. But what truly makes this go-anywhere biplane special is the remarkable AS3X® system that’s been
specially tuned to give you the feeling of fl ying a much larger model. AS3X stability works especially hard so
even when wind conditions are moderate, you experience the kind of smooth fl ight that makes you want to
fl y more often.
A thorough read of this manual will help assure that you’re well equipped to successfully enjoy all the
benefi ts this outstanding ultra micro model has to offer.

Prefl ight Checklist
1. Charge fl ight battery.
2. Install fl ight battery in aircraft (once it
has been fully charged).
3. Bind aircraft to transmitter.
4. Make sure linkages move freely.
5. Perform Control Direction Test with
transmitter.
6. Set dual rates and expos.
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.
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
model.
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.
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). 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 fl ight
battery.
4
Always disconnect and remove the Li-Po battery
from the aircraft after each fl ight. 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 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 model.
NOTICE: Repeated fl ying to LVC will damage the
battery.
Transmitter and Receiver Binding
Y
EN
Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifi er)
code of a single specifi c transmitter. You need to ‘bind’ your chosen Spektrum
equipped aircraft transmitter to the receiver for proper operation.
Any full range Spektrum DSM2/DSMX transmitter can bind to the DSM2/DSMX receiver. Please visit www.
bindnfl y.com for a complete list of compatible transmitters.
Binding Procedure
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.
1. Refer to your transmitter’s unique instructions for binding to a receiver (location of transmitter’s
Bind control).
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 the transmitter controls are neutral and the 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 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.
