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® ultra micro flybarless
helicopters, the specifically tuned AS3X System
for airplanes helps invisibly correct for turbulence,
torque and tip stalls when encountered.
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

Charging Warnings
The included battery charger (EFLC1000) has been
designed to safely charge the Li-Po battery.
CAUTION: All instructions and warnings must
be followed exactly. Mishandling of Li-Po batteries
can result in a fi re, personal injury, and/or property
damage.
• By handling, charging or using the included Li-Po
battery, you assume all risks associated with
lithium batteries.
• If at any time the battery begins to balloon or
swell, discontinue use immediately. If charging
or discharging, discontinue and disconnect.
Continuing to use, charge or discharge a battery
that is ballooning or swelling can result in fi re.
• Always store the battery at room temperature in a
dry area for best results.
• Always transport or temporarily store the battery
in a temperature range of 40–120º F (5-48º C).
Do not store battery or aircraft in a car or direct
sunlight. If stored in a hot car, the battery can be
damaged or even catch fi re.
• Always charge batteries away from fl ammable
materials.
• Always inspect the battery before charging and
never charge dead or damaged batteries.
• Always disconnect the battery after charging, and
let the charger cool between charges.
• Always constantly monitor the temperature of the
battery pack while charging.
• ONLY USE A CHARGER SPECIFICALLY DESIGNED
TO CHARGE LI-PO BATTERIES. Failure to charge
the battery with a compatible charger may cause
fi re resulting in personal injury and/or property
damage
• Never discharge Li-Po cells to below 3V
under load.
• Never cover warning labels with hook and loop
strips.
• Never leave charging batteries unattended.
• Never charge batteries outside recommended
levels.
• Never attempt to dismantle or alter the charger.
• Never allow minors to charge battery packs.
• Never charge batteries in extremely hot or cold
places (recommended between 40–120° F or
5-48° C) or place in direct sunlight.
