i am building a rc/robot mower.

most of the youtube videos show the sabertooth motor controllers being used to connect the rc receiver to the dc motors.

But here in Australia, the sabertooth i need cost about 200 dollars. RC esc sell for about 10 dollars.

What is the difference between the esc and the sabertooth and can i use an esc instead?

the specs i have on the motor and battery are 12v 10amp normal, 35amp stall. and my rc is a flysky

The Sabertooth Motor Controller is for driving DC motors, where most RC escs are for driving AC (brushless) motors. If the motor you have is a DC motor there are plenty of other motor drivers out there that can supply the 35A stall current, that you might find cheaper in your country.

I have listed some below

  • $\begingroup$ thanks for the list Mark. i will check them out. although victor and cytron look to be single, so have to double up on them. this esc is for brushed motors and is $10. ebay.com.au/itm/… $\endgroup$ – Anton Apr 14 '17 at 22:09

i have ended up using 2 RC ESCs they can easily handle the 35 amps and 12v. the flysky remote also allows mixing so that the 2 motors/escs can handle skid steering on one stick of the remote. So much cheaper
