Ahh I see! I've heard that the Botbitz 85s are able to cope with a lot of amps going through them, I vaguely recall Nick (Overkill) mentioning he ran a Mag on one for a weapon... Think it might have been modified a little to only use one direction but still they're impressive! I'm planning to run my heavy on a pair in testing (wheelchair motors on 6s) just to see how they get on! Mainly because I have some, but also because the 'proper' heavy ESCs are a bit out of my budget at present haha
