Ok so I know these haven't even been announced in the States yet but I'm already thinking the Losi mcro brushless system would be great, more for efficiency thatn speed. So the next thought is obviously batteries. I'm not very familiar with Lipo's so I may be off base. The losi 2S battery is 180mAH but doesn't really fit the design of HPI H-02 chassis. I was thinking the batteries from either a minium or a blade MCX would be great in pairs. I realize they are only between 110 and 130 mAH, but people are getting 20 minute run times from the 180 in the miro-t.
