My GTB2 is a dud!
I just wired up my GTB2 into my VTA car with a 21.5 SS and on any throttle position other than "creep" the motor pulses. Most noticably at lower speeds and a bit less at each progresive "step". I double checked all my wiring and ran the hall sensor test and everything appears to check out fine. I even tested it on 13.5 and 17.5 with the same results. I guess I'll take one more close look at it before I have to send it back and put the old Havok back in. I was just so excited that I could finally run two classes this week, but it's not looking so good anymore.
This is my first less than perfect Novak piece out of 4 ESCs and 6 motors.
