If you take apart a standard garden variety rc servo, you find a motor, some kind of gear train, and a potentiometer
If you take apart a linear actuator you find a motor some kind of gear train and in some cases a potentiometer.
So functionally they are more or less the same type of device, the main difference being, that the LA has a multi-turn pot, and the servo has a single turn pot.
Now then if I want to use a Roboteq unit to drive a linear actuator for steering, and have it function like a real powerful servo, where do I go from here?

you would simply need to wire the pot and the motor to the controller. You will find details in the product manual and on the RC auto application page at dev.roboteq.com/dev1/robotics-motion-con...size-automobile.html

Cosma you know those kind of days, when the ole brain just doesn\'t work like it is suppose to, well when I posted my OP I was having one of those days. But now I have a complete weekend to figure things out, and after enough coffee the ole brain is working just fine, at least for now.
Is the 2550 the only model that can be hooked up in this way? it seems like a bit of overkill to use a 120 amp controller to run a 4 amp motor, granted when I build the machine, I will probably use a larger controller.
It appears that my main drive motor will take less than 50amps @24VDC full load, but the linear actuator I like is only available with a 12VDC supply. I see a potential problem using only one controller for both motors.
I will think things out and see if there is another approach.

All our controllers can be used that way. The AX1500 looks like it could be your best choice.

Also, one channel can be configured to never output more than 12V while the other can reach the full 24V battery voltage.

Oh-Oh the gears are turning now. I Guess I have some reading to do.
