DELIVERS BREAKTHROUGH PERFORMANCE
The AS3X System for airplanes is an electronic
enhancement system that makes it possible for you
to experience super-smooth fl ight performance, yet
still have full control authority for sport, scale or 3D
fl ight.
Turbulence, torque and tip stalls are just some of
the many complications to assess when trying to
achieve smooth fl ight. The Horizon Hobby world-
class team of RC pilots developed the AS3X System
for airplanes based on the successful use of AS3X
with ultra micro fl ybarless helicopters. The AS3X
System invisibly helps with complicated corrections,
allowing you to experience ultra-smooth fl ight
performance that feels so natural that you’ll quickly
build confi dence in the capability of the airplane.
AS3X system setup is easy. Just bind your DSM2 ™ /
DSMX ® transmitter to the model using a basic
airplane program and AS3X will assure that the
locked-in feel and control authority you want is
instantly at your command to help show off your RC
pilot skills.
AS3X will innovate the way you’ll want to fl y now
and in the future. To see what we mean, go to

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.

6. Adjust fl ight controls and transmitter.
7. Perform a radio system Range Check.
8. Find a safe and open area.
9. Plan fl ight for fl ying fi eld conditions.
When a Li-Po battery is discharged below 3V per
cell, it will not hold a charge. The Beast 3D 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. Before
storage, charge the Li-Po battery to full capacity.
During storage, make sure the 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 fi ve 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.
