Default Novak Brushless 13.5 problem

ESC: Novak GTB
Motor: Novak BL 13.5

At first, sometimes there would be a delay between pulling the trigger, and the car getting power from a dead stop. I'm not talking about a slight delay, I'm talking about a full 3 count sometimes. And occasionally the car was short on punch to the point where I just didn't have enough to clear a double that I was clearing easily before.

After awhile, it was no longer a delay, it was just dead. Then I noticed that the times that it wouldn't restart were times when it stopped spinning in the same spot (the flat side of the rotor facing towards the back of the car) and if I gave it a little push with my fingers, it would start moving.

We took it apart and sprayed it out (thanks John Sterling), no change, so I don't think it's dirt inside the motor. I'm new to brushless, but my theory is that there is a sensor out in that spot.

Does anyone have any ideas? Are the sensors replaceable? Am I doomed to buy a new motor? Should I just wait until monday and call novak?

Thanks for reading,

...I'd call NOVAK and talk to Charlie.

I've heard a few of these stories...but I don't recall what the answer was.

just make sure your end points on the radio are set right and try to reprogram it if that does not work you might have send in
