FUTABA T32MZ Instruction Manual page 65

This function is for adjusting the sticks, switches, and
trim characteristics. It is not unless necessary.
This function reverses the operation signal of the sticks,
switches, trimmer levers, and knobs.
Note: This setting reverses the actual operation signal,
but does not change the display of the indicators
on the display. Use the Normal mode as long
as there is no special reason to use the Reverse
mode.
This function sets the servo response and hysteresis for
stick operation for each condition. The control feeling of
the stick can be adjusted to match the aerobatics.
Usually, this calibration is unnecessary.
Please perform this calibration, only if a change at the
center of a stick should arise after prolonged use.
