Control Centering
Before the fi rst fl ights, or in the event of an ac-
cident, 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,
return the transmitter trim to zero and adjust the
linkages mechanically so that the control surfaces
are in the fl ight trimmed position.
Settings for Servo Arms
This illustration shows the factory settings for
linkages on servo arms. After fl ying, you may
choose to adjust the linkage positions for the
desired control response.
This illustration shows the factory setting for the
Elevator servo arm on the servo.
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.

Elevator servo arm
IMPORTANT:
The factory setting for the elevator
servo arm is
one tooth forward from a 90°
angle
to allow equal elevator defl ection up
and down. All other control surface servo arms
should be set to 90°.
