You should bind your aircraft and transmitter before doing these tests. Move the controls on the transmitter
to make sure aircraft control surfaces move correctly and in the proper direction.
Make sure tail linkages move freely and that paint or decals are not adhered to them.
Control Direction Test
Settings for Control Horns
The following illustration shows the factory settings
for linkages on the control horns. After fl ying,
carefully adjust the linkage positions for the desired
control response.

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.
Centering Controls After First Flights
For best performance with AS3X, it is important
that excessive trim is not used. If the model re-
quires excessive transmitter trim (4 or more clicks
of trim per channel), return the transmitter trim
to zero and adjust the linkages mechanically so
that the control surfaces are in the fl ight trimmed
position.
