Or contrary to popular belief of many racers, sensorless systems are now extremely smooth (just ask anyone who uses a system like the Mamba Monster Max combo in a 1/8 buggy or truggy conversion), just as smooth as sensored systems, so you could go with like a Mamba Max ESC with a good sensorless racing motor. The advantage of systems by brands other than Novak are that most are now computer programmable, a big plus for racing, because there are so many tuning options, plus the LiPo cutoff is built right in and you can set it right from your computer. Now don't get me wrong, Novak systems are good for racing, it's a known fact, however at a lower cost, you can get a high quality sensorless system that has LiPo cutoff built in, which means less weight because you don't need and external LVC, and will be just as smooth as a Novak system and could easily be faster as well as more tunable.
