The K-Line S2 is crazy fast.  By most accounts RMT used different motors in the Bang that were a little calmer, giving a more reasonable speed range.  One trick a lot of folks do, is to rewire the motors in series instead of parallel, so that each one gets half as much voltage.  It also causes the motors to "nudge" each other- when one stalls, the other gets more voltage, etc.  Since the wheels can turn the motor on these, the series wiring works OK, but the Bang is still a better starting point.  You shouldn't try to make a silk purse out of a sow's ear.  My $.02.
