Motor problems on my excavator?

[elliot330]

Kalle,,

have you tried swapping the motor wires at the speed controller from left to right, see if the problem moves tracks? Have you recalibrated the Sabertooth after fitting the CTI module, ie show it where full forward is and full reverse on both channels. Can you display your servo positions in the radio via a graph? When in reverse are the bars the same lenght. Are the end points set to 100% on both channels?

Just a few quick easy things to try first.
