Reverse can be disabled on the MGM or Warrior controllers. Both 120 amp versions are rated for 120 amps continuous as well(MGM and BK). If you plan on pushing the envelope, the 9920 warrior is plenty, as is the MGM 12012. For racing with 6 cells or 2s Lipo, I agree with the above recommendations. The Novak and LRP systems are perfectly matched for low cell count racing with smooth, consistent, driveable power. For pushing the envelope, the systems available here are the ticket. :)

edit - I also carry the Novak and LRP systems, actually. :)

Thanks.

My pleasure. :)

The bk 120 20 warrior or micro can have the brakes and reverse diabled. It can have just reverse to. It is a 120 amp constant.
