Keith, I thought you'd get some replies from the who built these, but I don't think anyone really knows what kind of current the drive motors pull. If I was taking an educated guess, I'd say under hard use, I doubt the motors would pull more then 12 amps. Gear motors like this really aren't power hungry. I'd bet you would be well within the limits using a Sabertooth 2x12. The surge rating of the ESC is higher then the continuous 12 amp rating. I believe it can handle 20-25 surge amps for a few seconds. I know guys are running these with Servonaut M220 ESCs and those are rated for 20 amps. If you have doubts, the Sabertooth 2x25 would definitely handle the loader without any problems! I think you'd be very hard pressed to get these motors to pull more then 5-8 amps. If they stalled out, MAYBE they'd pull closer to 12 amps, but I doubt it.
