Programming Setting 2 –Cutoff Type
Cutoff describes the way the Pixie-7P handles a low voltage situation. There are two options for cutoff type:
Option 1: Hard cutoff with restart*
Option 2: Soft cutoff
A Hard Cutoff (the default value) will turn off the motor when a low-voltage condition occurs. Moving the throttle stick to the lowest (off) position, and then throttling back up will restart the motor.
A Soft Cutoff reduces the throttle level to keep the voltage at or near the cutoff voltage level. A soft cutoff is not recommended because it is easier to accidentally run the batteries down to a point where the
receiver and servos stop responding or battery damage occurs.

Programming Setting 3 – Throttle Range
Option 1: Auto throttle calibration*
Recommended for aircraft use
Option 2: Fixed throttle range
Recommended for helicopter use
Auto Throttle Calibration is a feature of the Pixie-7P that automatically adjusts the throttle range to match the range of the transmitter in use. In most cases, Auto Throttle Calibration is desirable, however,
in some cases (such as with a helicopter tail rotor control) a fixed throttle response is desirable.
