Sensor Issue - Novak

I have tried this with 2 ESCs a Havoc 3S and a GTB2, Using a Ballistic 10.5

Initially I was running it with the Havoc, and the tuck shut down during practice. Now when I power it up, and pull the throttle, the ESC flashes the red and yellow light twice and restarts.

After trying a new sensor cable. And verifying the stator is functional by trying the motor with a sensor-less ESC.....

I tried a brand new GTB2. After doing the initial programming. the ESC powers up and the RED and BLUE lights go on solid. No response from the motor at all.

Ran the Timing Sensor Test, I understand one light should turn at a time as you rotate the rotor. But the Red and Yellow light always turn on at the same time, and then aternate to the BLUE LED.

I am guessing this means the Sensor is shot. But looking for a second opinion.

Sorry for being so long winded, Just trying to be thorough.
Thanks for your help.

Anyway, my Havoc setup would cut off for no apparent reason since the first run. I tried all sort of gearing but Last night, at the track, it just stopped working for no apparent reason. The motor and speed control was cool. The red and green light was blinking and throttle input did not respond. Turning it off and on but then it would stop again.

I am taking it in for repair soon but I just want you guys to know of my experience with this setup.

It just stopped running and I could get no further throttle response from it, no matter which battery I put in. I am of the opinion that the Havoc is just a piece of garbage. I may or may not send it back in for repair. The way I feel now, I just might throw it in the trash, where it belongs, and get a different speed control. Chalk it up to a lesson learned about cheap ESC's. Worthless piece of crap!

Didn't get more than half a lap before it just stopped. Came back on and I got around the backside of the course, and it cut out again.

I used all sorts of batteries (NiMs, Lipo's) and it still cut out. I took all the electronics out of the car today (Tamiya DB01 4wd buggy) to inspect it.

It's at the point where I can literaly tap the heat sink and it'll turn off and turn on again. Seems to do it with any slight impact. Imagine in an off road car what that'd be like. Every fricking jump it cuts off!

I've been very pleased with Novak products in the past, but this Havok system is causing more "Havoc" than fun!

Novak, what do I need to do to send it in for repair?

I've never touched any of the wires it was all connected and soldered right out of the box. I had th spend 15 bucks to have it shipped, they got it friday, and still no response.......tried emailind today...see what happens. Guess i should be happy its not the esc like you guys.....not yet at least

to Steve Weiss, I have sent you an email to your Novak address in regards to this problem. I hope living in Australia won't prevent me from a fast reponse in sorting this issue out.

Sorry your luck with Novak sucks. I ran a year of bashing and a season of racing on my Havoc. This is the only issue I have encountered. And from the looks it it, its only a $15 sensor and has nothing to do with the ESC.

I was just looking for some insight from some one with real technical experience. Not some one who simply lists other peoples failures as their own knowledge.
