When you're intending to power your bot with some of the more current-hungry motors out there, it's time to beef up to a larger speed controller. The RDFR33 is a whole new design over the RDFR2x series. It can handle more current than the above models, and has screw terminals for all the connections. Also provides single stick mixing. This is the MOST POPULAR model for middle to large-sized robots!
