Default Re: sabertooth controller and servo issues

I am assuming you have the ESC in dual mode and not tank drive. In dual mode one channel makes both tracks drive forward or backward and the other channel is used to steer. In this mode the ESC will be very touchy and you will have to be light on the controls if you just push the steering full left or full right the tracks will go full speed in opposite directions for a 360 deg spin.

Now if you put the ESC in tank mode each track will be controlled by a separate channel and there is no mixing. This will make driving a lot smother but you just can't have the drive all on one stick.


As for the servo you are going to have to trim the servo to find its center and it is no different than centering a servo for steering. This is due to the fact that the two resistors are not perfectly matched so it is not sending a zeroed feedback back to the circuit board. You have to fine tune it with the radio but the benefit of replacing the pot with the resistors is you are getting a constant feedback.
