Control Centering; Factory Control Horn Settings - Horizon Hobby UMX A-10 Thunderbolt II Manuel D'utilisation

Control Centering

Before the first flights, or in the event of an
accident, make sure the flight 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. Ensure SAFE Select is OFF.
2. 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.
3. When needed, use a pair of pliers to carefully
bend the metal linkage (see illustration).
4. 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. Do not trim the
aircraft while SAFE Select is active. Always trim
the aircraft in AS3X mode. If the model requires
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 flight trimmed position.

Factory Control Horn Settings

The illustration shows the factory settings for
linkages on the control horns. Linkage connections
on the control horns directly affect aircraft response.
