Sabertooth Dual 25A Motor Driver User's Guide

A note on certain microprocessor receivers
Some receivers, such as the Spektrum AR6000, will output servo pulses before a valid
transmitter signal is present. This will cause the Sabertooth to autocalibrate to the receiver’s
startup position which may not correspond to the center stick position, depending on trim
settings. This may cause the motors to move slowly, even when the transmitter stick is centered.
If you encounter this, either consult your receiver manual to reprogram the startup position, or
adjust your transmitter trims until the motors stop moving.
If you are having issues, and the ranges for your transmitter/receiver are known, you can use the
DEScribe software to tailor the ranges to your individual setup.
