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