Before the fi rst fl ights, or in the event of an
accident, make sure control surfaces are
centered when the transmitter controls and
trims are neutral. The transmitter sub-trim must
be set to zero. 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.
• Make the U-shape narrower to make the
connector shorter. Make the U-shape wider to
make the linkage longer.
IMPORTANT: Only trim this aircraft in Experienced
Flight Mode.
Control Centering
Control Direction Tests
You should bind your aircraft and
transmitter before doing these tests.
Perform the Control Direction Test in
Experienced Mode.
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.
Control Direction Test
This test ensures that the SAFE ™ control
system is functioning properly.
Assemble the aircraft and bind your
transmitter to the receiver before
performing this test.
1. Advance the throttle above 25% to
activate the SAFE ™ system.
2. Fully lower the throttle.
3. Move the entire aircraft as shown and
ensure the control surfaces move in
the direction indicated in the graphic. If
the control surfaces do not respond as
shown, do not fly the aircraft. Contact
product support for more information.
Once the SAFE ™ system is active, control
surfaces may move rapidly. This is normal.
SAFE is active until the battery is
disconnected.
