Control Surface Centering and Adjusting a Clevis
IMPORTANT: Perform the Control Direction Test before performing control surface
centering.
While SAFE is inactive, mechanically center the control surfaces.
IMPORTANT: Correct operation of the SAFE system requires sub-trim and trim at 0.
After binding a transmitter to the receiver, set the trims and sub-trims to 0, ensure
the servo arms are in the correct positions, then adjust the linkages to center the
control surfaces.

Dual Rates and Control Throws
Program your transmitter to set the rates and control throws to the values given.
These values have been tested and are a good starting point to achieve successful
