From what I understand, this was a long time issue with the old Shultze/Pletenburg combo as well. Awesome power and a great setup, but trouble if you ever started to roll backwards...it would supposedly rocket you faster in reverse if you tried to pull out of it.
The sensor designed motors are aware of the rotor position and how to compensate/correct rotation.
Don't get me wrong here, the Mamba is a good setup and has insane power capability, but if you need pure finesse from your motor then don't buy a Mamba. After switching the motor lead connections, I never really complained about mine until I moved from off-road to oval.
I don't think it's just the fact that it is senorless, the GM Genius 95 runs sensorless just as good as it runs sonsored. I think castle just didn't do a very good job. I spose when somethings as cheap as it is you wouldn't expect a perfectly running speedie.
My vote goes to the Novak.
