The best cure is the sinitered rotor. It dropped my motor temp drasticly. With the sinitered rotor I'm running a high 36mm rollout and it comes off the track at 130 degrees. I've run the rollout even higher, close to 38mm, but I'm at my personal driving limit in the 36.8mm range.
the motor can pull a high roll out , i geared mine to the moon (1/12th scale)

Hi Guys,

I'm not sure where to start, so I'll just start.

Temp with the 13.5 is a bit different. With the sintered Rotor, you'll see about 130-140 as the max. I've got reports from drivers of gearing up past that temp, with no laptime change, sometimes "felt" slower.

With the regular Rotor, you want about the same max temps. The problem if you overheat the standard Rotor is that it pretty much NEEDS to be replaced at that stage. After they get hot, they get weak, this makes the motor run hotter and the cycle continues.

Now, I've been doing the warranty inspections here at Novak since 2001. Pretty much I'm the only guy here that does them "full time". I've seen every color and condition of ESC you can imagine. From good to bad. Now since BL has come around, things are more tricky. The question of Did the motor kill the ESC or was it the other way around is common. From my experience testing Novak "systems" it's never both, it's one or the other very very clearly. The motor has a defect, or the ESC does.

Typically I don't think a motor will "kill" an ESC (at least not an Orange one) The GTB and the SS have ESC protection for this. EVEN if you disable the MOTOR temps sensor, the ESC's is still there to protect it. Disabling the motor temp protection only runs the risk of shorting the motor VIA it being very very hot, or getting it so hot it goes bad and shuts off the ESC.

Other products are not this way, So when the ESC "lets go", it also applies a short across the motor coil. This in turn, shorts the motor out completely. In that case, it's fairly safe to say, the ESC killed the motor.

I'm not going to post that one ESC or the Other ESC has this condition. I really hate when people do that to us. If you'd like some information on this topic drop me an email anytime.

And as always, feel free to email me directly anytime. The first think I do when I come in, and the last thing I do before I leave is emails.

Thanks
Charlie

Good run Saturday Chance. I didn't know you had a sintered rotor in yours. Good to hear it helped out with some of the issues. I'll have to try one out sometime next year. I'm all moneyed out after buying the 2 XRay's and XMas shopping! But we'll see what Santa has to bring I guess. Hopefully I'll get some more green and I'll try one out. Catch ya Saturday...

Thanks Jimmy, I just got lucky. You need to get one, I would like to see just how fast they really are. I think they're faster than stock, I just lack the skills.
But about the sinitered rotor, more people are using them than you think, there's maybe two or three that don't have them... yet. It's just nobody wants to say they are using them for some reason. It's easy to tell, just look at the size of their pinion/spur gear. LOL

I used profile #3 if you have the sintered rotor leave it with #3 but if you have the stock rotor yes use #3 but bump up the drag brake some

GEAR IT UP HIGH....really high. Don't make the mistake that I did or you might think the 13.5 is a total waste....(my example, C027 used 30/116, 13.5 I am using 36/108...yes, that much of a gear ratio different)

Nope, it ships with the bonded rotor. This is the part you'll want when you're ready to upgrade it:

Only 3.5R comes with sintered rotor and ribbed motor can
4.5R come with ribbed motor can but with standard rotor.
The rest 5.5R - 7.5R come with standard rotor & motor can.

I wish the next generation of velocity motors all come with sintered rotor & ribbed can.
