I think I'll just send mine in, I've sent quite a few emails and still no reply. I'm hoping I can get the ball rolling if I ship it.

I didn't have any glitching problems when I ran a Futaba 3003 servo. I noticed the motor would glitch when I turned the wheels left and right after installing the HT 645mg. I tried an airtronics servo with metal gears and it did the same thing. I didn't realize it until now but my car shut down on me for a few seconds a few times also. I didn't think it was related at the time but now I think it was.

After calling Novak, they said the Havoc Pro needed a software update. They received it at their location in Irvine on May 7th. As of today, I have not received an email notification letting me know it is on the way back. Plan to be without your ESC for at least 3 weeks. I am skeptical whether the software update will do the trick. If it doesn't, I will let them know of my dissatisfaction with there product. However, I have heard a lot of the same problems are common with the MMP. If it isn't fixed I will try the capacitor in the Rx. I would go back to the Futaba 3003 but I went through 2 sets of gears and don't want to keep putting new gears in it every race.

There seem to be a lot of common issues with High Torque servos, digital or analog, and 2.4 spread spectrum systems

I got a Havoc 2S when they came out and had problems with it cutting out for no reason. Sent it back for a software upgrade and it has been fine since. Two guys where I race sre going to have to send their Havoc Pros back because they are cutting out when they shouldn't. Maybe stick with the GTB and be happy you have an "old reliable" speed control.

FWIW I run 9100s servos with both of my Novak ESCs and don't have glitching.

I spoke to the tech last Friday to see if the software update made a difference. He stated it tested fine. I asked if he tested the Havoc Pro before the unit received the software update to have a base line and see if it failed any of the tests. He said no. I asked how he knew the software update fixed anything. He couldn't answer other than saying it passed the tests. He said it would ship out Monday 5/17. After not getting an email Monday, I called Novak Tuesday. I was told they were waiting for parts. I was confused and asked, What parts? It was a software update. They told me the tech decided to swap out the Havoc Pro with a GTB and they were waiting for the shipment to come in but don't worry the GTB is a better ESC.

So, I received the ESC and sure enough, they sent me a GTB. So why did they do that? Is something wrong with the Havoc Pro software? I'm so confused with this. Is the GTB a better ESC? What are your thoughts???

I am happy with my Havoc 3s/HV4.5 and now that I am using a capacitor in the receiver I have had no issues. The Havoc 2s and Havoc Pro are very similar IMHO. The GTB is a proven ESC from Novak. I know many people who are really happy with them. Let's face it, with the power the HV motors deliver you don't need the Tekin or MMP timing advance. Then why pay the extra money for them. In Stock class I can see it and I am planning to get the new Havoc Pro SC for my 17.5 Stock SC10.

The on-resistance (based on the MOSFETs) of controllers is important: our GTBs, SLYDRs, Havoc Pros, and (upcoming) Kinetic and Havoc Pro SC, all have very low (0.00040 ohms) on resistance and a 540 motor limit of 3.5 turns. Our Havoc 2S, 3S, XBRs are 0.00120 ohms, with an 8.5 turn, 540 motor limit.

So, because of the number of MOSFETs used in the esc, the performance of the lower on resistance controllers is superior. As the new ROAR Sportsman Class with non-timing escs develops, low on-resistance controllers will be very important.

TURN OFF THE LIPO CUTOFF
The cutoff was designed for bashers that run till the battery is flat dead. The Havoc is automaticly turned on as default as opposed to XBR and GTB you had to turn it on purposly.
Novaks lipo cutoff is just too sensitive. And if your in a 10.5 or above class you don,t need no stinken fan............
