Has anyone found a way around the thermal sensor issues with the Havoc ESC. This setup is making me crazy. I'm sick and tired of having this ESC thermal when the motor temps are around 145 degrees F.
I tried both the 17.5 Speedpassion V3 and the 17.5 Duo2 this week and the Havoc won't arm with either of them.
I have been dropping my gearing several pinion sizes over the last couple weeks. I'm at point where I'm at top speed 15 feet onto the straight and watching the pack pull awayand It still thermals 2 laps before the end of a race. Pretty bad for 17.5 rubber sedan. If I can't get around the programming, I'll be done with Orange stuff forever.

We should have an update that will fix this type of problem.
Please send the ESC in to us along with a warranty service form and a description of the problem and we will get you sorted out!

I got the same problem. The Novak 21.5 motor had been running around 142 and the Havoc would thermal 4 minutes into the race, even with fan over ESC. I will be sending mine in by this Friday.
Steve does this effect all the ESC's? I have one and have not been running it yet but I have been having all my friends buy the same thing. This thread has me concerned and I don't want this to affect our in door season.

The Havoc 1S, Havoc 2S and Havoc 3S controllers were designed to be compatible with thermally protected motors:

MOTOR COMPATIBILITY
These controllers include Thermal Overload Protection circuitry to protect the system from overheating and damage. In fact, the ESCs will only operate with brushless motors that have built-in thermal protection that follow ROAR guidelines, such as Novak’s new Ballistic Brushless Motors (#3603-#3621), Novak Velocitis and SS Pros. This sophisticated feature ensures a fun day at the track without the worry of overheating.

We have been making running updates to the Havocs since their introduction. The latest batches should not have such a conservative motor temperature cut off as the earlier batches do.
If you are having trouble with your Havoc shutting down early, send it in and we will get you updated to the latest specification!

Aww man, I just ordered a havoc 17.5 system from Tower! Steve can you tell me if they have the latest batch or the earlier ones?
That would suck to have to send it in as soon as I get it! I run in South Florida and its HOT down here!

This is good news Steve. Thanks for the update. I will be sending mine in tomorrow. The Havoc system I bought was the one with the 21.5T motor. Do I send the ESC only right?

Steve -- do the GTB and the older XBR or SS+ have this same compatibility issue? I seem to recall seeing somewhere (?) that the newer GTB's don't use the motor temp sensor feed, but now I can't find it...???

The earlier controllers, and the just shipped Havoc Pros, are compatible with all mfgs' 540 size sensored motors. And, they do not limit the cut-off motor temp, even on Novak motors.

had the same issues, What I did was run a battery with a lower C rating, from 40 down to 28-30 c, never had a problem after that. Maybe the novak guys can look into this, especially I'm planning on getting a 1s havok when they come out and 1s usually has 40-50 c rating.
