Control Centering

Before the fi rst fl ights, or in the event of an
accident, make sure the fl ight control surfaces
are centered. Adjust the linkages mechanically if
the control surfaces are not centered. Use of the
transmitter sub-trims may not correctly center the
aircraft control surfaces due to the mechanical
limits of linear servos.
1. Make sure the control surfaces are neutral
when the transmitter controls and trims are
centered. The transmitter sub-trim must
always be set to zero.
2. When needed, use a pair of pliers to carefully
bend the metal linkage (see illustration).
3. Make the U-shape narrower to make the
connector shorter. Make the U-shape wider
to make the linkage longer.

Trimming

After adjusting transmitter trim in the air or on
the ground, do not touch the control sticks for
2 seconds. This allows the receiver to learn the
correct settings to optimize AS3X performance.
Failure to do so could affect fl ight performance.

Control Horn Settings

The illustration shows linkage positions chosen for
the best aerobatic response. Linkage connections
on the control horns directly affect aircraft response.

Dual Rates

To obtain the best fl ight performance, we
recommend using a DSM2/DSMX radio capable
of Dual Rates. The suggested settings shown here
are the recommended starting settings. Adjust
according to the individual preferences after the
initial fl ight.
NOTICE: Do not set your transmitter travel adjust
over 100%. If the TRAVEL ADJUST is set over
100%, it will not result in more control movement, it
will overdrive the servo and cause damage.
It is normal for linear servos to make signifi cant
noise. The noise is not an indication of a faulty
servo.
