Control Centering
Before fi rst fl ights, or in the event of an
accident, make sure the fl ight control surfaces
are centered. Adjust linkages mechanically if
control surfaces are not centered.
Use of the transmitter trims may not correctly
center the aircraft control surfaces due to the
mechanical limits of linear servos.
1. Make sure control surfaces are neutral
when the transmitter controls and trims
are centered. Where possible, transmitter
sub-trim must be set to zero.
2. When needed, use a pair of pliers to
carefully bend the metal of the linkage
(see illustration).
3. Make the U-shape narrower to make the
connector shorter. Make the U-shape
wider to make the linkage longer.
NOTICE: When using a programmable
transmitter, do not use Sub-Trim to adjust the
center position of the servo.
NOTICE: Never set Travel Adjust above
100%. Ultra Micro servos are unique in that
they are calibrated to reach maximum travel
at 100% travel adjust. Increasing the value
above 100% will NOT result in more travel, but
can cause the servo to lock and will result in
a crash.
Settings for Control Horns
The illustration shows factory settings for
linkages on control horns. After fl ying, if you
want more control throw, carefully adjust
linkage positions for desired control response.

1. Charge fl ight battery.
2. Install fl ight battery in aircraft
(once it has been fully charged).
3. Bind aircraft to transmitter.
4. Make sure linkages move freely.
5. Perform Control Direction Test with
transmitter.

6. Adjust center of gravity.
7. Perform a radio system Range
Check.
8. Find a safe and open area.
9. Plan fl ight for fl ying fi eld conditions.
