Except with CCPM helicopters, always complete your servo reversing prior to
any other programming. If you use pre-built
ACRO
GLID
functions that control
multiple servos, such as
FLAPERON
or
V-TAIL
, it may be confusing to tell whether
the servo needs to be reversed or a setting in the function needs to be reversed.
See the instructions for each specialized function for further details.
Always check servo direction prior to every flight as an additional

End Point of servo travel adjustment
(
END POINT
, also called
EPA
): the most flexible version of travel adjustment
available. It independently adjusts each end of each individual servo’s travel, rather than one setting for the servo that
affects both directions. Again, for CCPM helicopters, be sure to see
SWASH AFR
(see p. 73) prior to adjusting end points.
Adjustability:
• Can set each direction independently.
• Ranges from 0% (no servo movement at all) to 140%. At a 100% setting, the
throw of the servo is approximately 40° for channels 1-4 and approximately 55
° for channels 5-8.
• Reducing the percentage settings reduces the total servo throw in that direction.
Examples:
• Adjust the throttle high end to avoid binding at the carburetor, and low end to allow for proper carburetor closure.
