Speed controller

Hi all,

I'm curious as to what you guys are using for speed control. I've had a dig around the site and I'm not really finding the answer I'm looking for.

What I'd really like to know is, are rc car speed controllers suitable? I've been looking at them on eBay and they appear to offer high amperages, forward and reverse and relatively cheap prices.

Do these things work OK, with Arduino?

Are there better alternatives?

Does someone know of a post that will give me some insight?

Thanks 6677,

I’ve been looking at gearboxes and the motors in the ones I’m looking at pull about 45amps, so I do need something, with a bit of juice.

Would you suggest something other than rc car ESC? 

I have used an L298 previously. I also need to keep costs down, because it’s grim up north.
