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.

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.

Preﬂ ight Checklist

The Incredible AS3X

system Aerobatics Experience

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

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.
