Hey Jim. There are a couple versions available that are RC ready. Meaning the controller has RX leads which plug right in.
I bought the smallest version. It runs on 6-18V and can deliver 5 amps continuos to each motor and peak output of 10amps for short periods.
The next size runs on 6-24V and delivers 12amps continuos.
Really great little unit. Only flaw or problem I can see is the BEC inside it can only handle 1 amp so if you have a servo that uses high amps it will cause the controller to shut down.

Anyway, here is the link to the page of various sabertooth controllers.

Back from a week long trip to my home town. Finally got a chance to do some work on the dozer. Time is a wasting so pulled a good session, 6hrs last night and atleast 8hrs today.

Got the blade working and ballast in the front end. If I did this again, the one thing I would do different is mount the motor drives a little lower and eliminate the rocking or tilting from front to back.

Not sure how heavy it is now with added weight?... Maybe 3lbs now? I want to add more but using plastic stock rollers and track frames, I can't get to crazy.

Anyway, the new firgelli actuator for the blade.....

Here is a recent video of the dozer and what it can do.
I just placed it on a scale to see what it weighs with battery. - 4 lbs, 12 OZ.
It performs beyond my expectations and very happy
