Sorry to re open the thread, but has any one used these speed controlers before? I thought I heard someone did (or something similar) but does the low amp reverse afect the driving hugely? And do u think it could cope with two drill motor per ESC? I think forward would, but would reverse? http://www.ebay.co.uk/itm/270826285477?redirect=mobile (sorry if it's the mobile site, I've tryed to chnge it)
