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.
When centering the elevons, the control surface will
not directly line up with the edge of the wing tip
due to the wing tip’s washout. The top of the elevon
will line up with the approximate middle of the edge
of the wing tip in order to be level with the rest of
the wing (see illustration).
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.
Control Direction Test
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. Always keep throttle at the
low position during testing.
