Got a project in mind, but need a little help...

[Superbasher]

Hi everyone,
I'm looking at converting over a lightning 2 buggy to brushless, but I'm stuck on controller options. Now I've seen the thread on modding a MMM but I'm not too sure on that one. I was thinking of using a boat controller as from the ones I have read up on say they have a brake, now is it proportional? Or not enough for use in a car?

If a boat ESC wouldn't work, what would you reccomend?

Thanks :)

Matt.
