Prefl ight Checklist

1. Charge fl ight battery.
2. Install a fully charged fl ight battery in
the aircraft
3. Bind aircraft to transmitter.
4. Make sure linkages move freely.
5. Perform Control Direction Test with
transmitter.

The Incredible AS3X

The Artificial Stability – 3 aXis (AS3X) system
developed by Horizon Hobby product developers is
an electronic advancement that virtually eliminates
common barriers RC pilots fight on a regular
basis. Its combination of multi-axis sensors and
exclusive software reduces the correction workload
normally required to combat turbulence, adjust for
torque effects, p-factor and goes even further by
stopping or significantly delaying tip-stalls. Beyond
an increase in stability, the AS3X system provides
enhanced agility you can use to perform aggressive
maneuvers with a higher level of precision more
easily.

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
aircraft.
When the motor power decreases, land the aircraft
immediately and replace or recharge the fl ight
battery.
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

system Aerobatics Experience

Now the AS3X system has been expanded to
an evolutionary level by providing multiple flight
assistance options. For the UMX AS3Xtra, there are
five pre-programmed flight modes to make complex
maneuvers such as knife edge, harrier and hovering
easier to accomplish. Change between AS3X modes
at the flip of a switch to best suit the way you want
to fly instantly. Not only will you feel as if your in
total command of a much larger expertly tuned
model, it delivers the kind of control confidence that
will unlock maneuver capability that some pilots
might take years to master.

AS3X.
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 4 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.
6. Set dual rates
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.
