Hello

I´m building a scratch tank and I have huge problems finding a Speed Controller.

I have two screwdrivermotors, That will operate around 40A, 12V and DC ofcource. But I cannot find any Speed Controller that fixes this!
Well, one I have found and that is the Sabertooth Dual Motordriver. But I would like to have 2 speed controllers, one to each motor. But I can´t find any that meet the requirements: Brushed, 12V and 40A. Aswell as I want it to go both directions.

What ESC do you have for your motors?

Theres a lot out there.

Like this one maybe: https://www.hobbyking.com/hobbyking/...d_Car_ESC.html

Just make sure its for brushed motors, and can take 12 V (I think 4-6 cells LiPo for example is 12 V or more).

The one you linked to is 7.4V and most of the ones I seem to find are about 7.4V. I find noone that meets all my requirements.

The Syren 50 from dimension engineering must suit?

Assuming you're building a 1/6 scale! What is the project?

Anyhoo I've been using these suckers for years in my larger scale warships. They're simple and robust too. I've wired motors in parallel without issue and they can handle lots of amps, up to 50A continuous according to their specs. I've also had them operate directly from a 12v lead-gel battery and they hardly even get warm.
