I took my 10.5T novak setup for a run today, and it seemed to get pretty warm. My gear ratio is set to novak's ideal 5.5:1 (its actually 5.56:1).

The thing is, I dont have a temp gun or anything to measure it with. So i was hoping that the built in "thermal protection" will shut the motor off in the case of it getting to hot.

Is that right?

no...


and there is no "ideal" gear ratio...

"Can a sensored brushless overheat?"

Yes.

Yes there is... Novak have a chart on their site that lists the FDR target of 5.5:1 for the 10.5T motors...

And a guide using info for many manufacturers here

So the question is more, can a sensored motor that is with an esc with thermal protection overheat?

So far I have a yes and a no so what is it?

If novak knew what they were talking about now days they would be still holding more market share...

The optimum ratio is dependant on track size, vehical weight, voltage, & motor.

Please DO NOT take any thing for fact on a chart other than a part number....

Yes & No... Novak Motors have temp sensors in them, Novak ESC's use them.
Do Novak Motors burn up? yes
but not a offten as their ESC's do.

So essentially, get a temp gun, a bunch of pinion gears, and hit the track.

And by the sounds of it a fan for the esc...

Thanks.

A fan might help, but odds are it will just stop working at some point.

Lol. Thats awesome.. Only just picked one up last week, had its first run today. Now I'm all paranoid...

Nah, just learn how to gear it for the track and keep the temp of the motor below 160F or 71C.

Our Havoc 1S, 2S and 3S systems have the motor temp sensors engaged when used as a system. However, when not using these escs, our motors do not shut off if you are over-gearing them or using them with improperly adjusted timing/boost escs. You can always contact [email protected] for assistance with Novak products.

What are you running this in? I like Novak and have not problems with their esc's or motors. Their gearing charts/recommendations are not the best I've seen though. Everybody likes to jump on Novak when they have an esc or motor go up, truth is every brand has bad apples. They just keep it quiet when it's their brand so they can keep talking smart. I've seen Tekin's, LRP's and Novak's have issues. Buy what you like, they all work.

It's a havoc 2s esc with the ss pro 10.5t. It's the combo pack. I've got it in my rtr kyosho tf-5 shaft drive tc. Probably more power then I should put through that chassis... But I couldn't bring myself to spend the same money on the 17.5. . The esc doesn't feel hot, nor does the lipo, I guess I'm just being paranoid, I'm going to order a temp gun, and a new spur and a bunch of pinions to give me a better range of gearing choices at the track. And while I'm ordering all that it can't hurt to grab a fan for the esc.
