After using the car for a few weeks, today I went to a new circuit, with very little grip. I though at first that the battery voltage was low, but I wasn,t. I even tried another Lipo battery and it happen the same thing again. The car suddenly stops, and after 2 seconds or 1, it works again, anbd then again it stops..It happened suddenly, not problems at all before...Any idea what this could be? I have broken a Ko Propo speedo two weeks ago and I would not want to have another one broken..

mine also has done this, keeps cutting out as if overtemp but esc and motor at only 30deg c.

shhot an email to [email protected] with serial number an prob im sure he will send quick reply.

Mine is at Novak for the second time with the same issue. All they want to do is update the firmware i talked with a Tech and that's what he said.
This is such a common problem with the Havok they should offer a cheap trade on something else or replacing it.

Well..thanks.I live in Japan,so I don,t know what to do...

It's to bad that they have had this problem for almost year and a half with no REAL fix. Replaced all three of mine with LRP's and guess what....no more issues!!!

what radio are you using? mine glitched like that once, when I was using a cheaper radio. Otherwise it has been perfect.

My havok 3s worked great for a few months until last night. Now it just seems to randomly stop accepting input from the receiver. Steering still works. The drag brake keeps working -- you can move the car and hear it braking. You can drag the car and move the motor to see if it's a rotor position sensing issue and it doesn't help. The motor is cool, the speedo is cool, the lipo is charged, and no error conditions are reported from the esc -- everything looks normal. Turn it off, then turn it on, bam, fixed!

Last night it screwed me over in one qualifier and in the first lap of my main. Honestly, I'm done with novak. Completely done. This is just totally unacceptable. Nine out of ten people I've talked to who ran or run novak at my track had stupid issue like this from random cutting out to false motor thermal shutdown.

Before this, I was geared lower than their recommendations with my ballistic 8.5 and my motor would thermal left and right. When it thermalled, the temp with a gun would be around 160 at the endbell -- their acceptable max range is 160-175. Put in a mamba max pro, motored up to a ballistic 7.5, left the gearing the same, put in a castle mamba max pro, and I can run the piss out of it and it doesn't go north of 130F.

Novak brushless speedos = FAIL. If you have one, good luck. I used to run novaks back in the day and they were great -- I was such a novak fan boy it's not even funny.

Have you talked to Novak support? Have you given them a chance to fix the issue. I have eight Novak Brushless ESCs in different cars, trucks, etc. Do they ever fail? Seldom, if they do; Novak has been A+ in working with me and getting the situation fixed.

Nope. I have no plans to either. I might send it in, but I'm replacing it with another castle mamba max pro regardless. I've been watching locals deal with novak failures left and right and I'm not playing the game. I'd rather just get another mamba max pro, have a cooler motor, and be done with it.
