Control Surface Centering

After assembly and transmitter setup, conﬁ rm that the control surfaces are

centered. If the control surfaces are not centered, mechanically center the

control surfaces by adjusting the linkages.

With the ﬂ ap switch in the up position, ﬂ aps should be adjusted so they are

even with the ailerons and/or the root of the wing.

IMPORTANT: DO NOT use sub-trim and trim to center control surfaces. The

AS3X system requires sub-trim and trim set at 0.

If adjustment is required, turn the clevis on the linkage to change the length of

the linkage between the servo arm and the control horn.

After binding a transmitter to the aircraft receiver, set the trims and

sub-trims to 0, then adjust the clevises to center the control surfaces.

Clevis Installation

• Pull the tube from the clevis to the linkage.

• Carefully spread the clevis, then insert the clevis pin into the desired hole in

the control horn.

• Move the tube to hold the clevis on the control horn.

Control Horn and Servo Arm Settings

The table to the right shows the factory settings for the control horns and servo

arms. Fly the aircraft at factory settings before making changes.

NOTICE: If control throws are changed from the recommended settings, the

AR636 gain values may need to be adjusted. Refer to the Spektrum AR636

manual for adjustment of gain values.

After ﬂ ying, you may choose to adjust the linkage positions for the

desired control response. See the lower table.
