We have a problem with bruiser 2, as it has very little power, we have a 5:1 reduction on the cheap eBay speed 900 like motors, but they stall a lot, on start up and turning etc, and then on top of that, the 2 25amp syren controlers we have controlling it just cut out when we try to turn or drive, it can just about drive forward if we bank it up slowly, but it would be very impractical for combat, so I was wondering what we could do, would adding the two spare motors onto it help, and what higher current controlers could we use? We were looking at the sabertooth 2x60 amp controlers, would they do? And do you think they could take the two motors? Any help would be appreciated, and this is basically our last day building the thing so speed is of the essence! Thanks
