Ah, ok, thanks a lot. This is why I'm worried about it, though; http://rc-monster.org/forum/showthread.php?t=19315

He burned up the MMM ESC with the 1527

But, I'm going to gear it for 35-40mph or so at first. And perhaps go faster if it handles that easily.

So, I guess I'll buy the 1527 with the Mamba Monster -- I can't get ahold of the 1524 anywhere.
