Calibrate

You can use the Calibrate menu to calibrate the travels, centre and any
intermediate points for all servos so that they move evenly and run only to the
permissible end-points.
Surface pairs such as ailerons and camber-changing flaps can be trimmed for
synchronised movement in this menu. The 5-point curve requires more
configuration work, but yields better results.
The menu shows a list of all the servos which can be used with your transmitter
type (9, 12, or 16 servos).
The sub-menu is identical for all servos.
Parameter changes are immediately reflected in the graph. The channel number
(receiver output) of the selected servo is shown above the graph.
REV/TRM
The REV/TRM parameter has two functions:
o
Servo reverse (REV) changes the direction of servo rotation. To
reverse the direction of servo rotation "open" the set point and
press the REV/CLR button: The entire curve is "reversed" and the
prefixes of all curve points change.
o
Servo trim (TRM) shifts all points on the servo curve in parallel. Use
the wheel or the +/- buttons to adjust the trim.
The set trim value results in a parallel shift of the curve. The curve points
are limited to +/- 110%. The shape of the curve remains unchanged until
the limit is reached. The effect is the same as the standard trim
procedure.
