sensorless not best then? Tekin motors work ok? have Tekin tested motors?

sensorless more powerfull than sensored answer NO!

read here > sensor vs sensorless

it give all answers sensored vs sensorless!

I as a buyer find it very hard to trust Novak's page because they have a vested interest in pushing sensored technology.

Sensorless and sensored are different technologies that's all. They both have their advantages and their inconvenients.

That article has been written by a company that has all its eggs into the sensored technology, do you really think they'll say that sensorless is better? If you want to know more about them, I recommend reading some material from outside the RC industry...

"I as a buyer find it very hard to trust Novak's page because they have a vested interest in pushing sensored technology."

so go buy a mamba or an R1 if and when you can get it. you'll find out why sensorless is dominating right now. don't get me wrong, the mamba is a machine. and it has NEVER thermaled on me (sorry novak, but i hope you have a new version in the works...). but for off road or other forms other then touring sensorless is better. and i have yet to get the low end rip (in tc) out of the mamba that a 5.5 novak has on the bottom.

tekins promise of never releasing the R1 until it is perfect is gone. and from experience (mine and others i race with), sensorless don't run novak style (ie delta (?) wind motors) without cogging. and that includes low wind motors.

so who are you going to believe now? accepting tekin's claim that sensorless is just as good or better then sensored is just as bad as not trusting novak...

no flame intended, but i have to give my 2 cents, as i've run every combo of brushless around.

Your post is quite confusing, I think you're pretty confused with the whole B/L technology and that's why you say sensorless when you should say sensored, etc...

GM have a system that runs better in sensorless mode than in sensored, and that's according to the BRCA national champion. I trust him better than you, no offence mate. I've not experienced any cogging either with my 4.5 or 3.5 (in 5-cell).

At least Tekin have aknowledged that in some applications a sensored system is better, and are doing their best to develop a system for that application.

yea that's what I was saying.

How can I trust a company that's saying 'sensored is better!' when they are the ones selling sensored technology? of course they're gonna say their stuff is better. It's simply marketing disguised as research. It confuses people who haven't done any research and convinces them into buying into sensored technology.

I'd rather take the advice from an objective person in this hobby.

"so who are you going to believe now? accepting tekin's claim that sensorless is just as good or better then sensored is just as bad as not trusting novak..."

I know you said 'no flame intended' but I find it very hard to take it any other way than a flame. and an uncalled for one at that.

I just re-read the Sensored vs Sensorless article from our website and I'm confused as to why some of you see it as so prejudicial and lacking in objectivity.

The different brushless technologies are described correctly, in my opinion. Perhaps, you could point out just where Novak claims that "sensored is better"?

There is no need to trust Novak's information about brushless technology. By all means read whatever you can find. What other RC company has taken the time to offer a detailed explanation of the differences and posted that information to their website?

How about posting those links?

"the Sensor based feedback system is much faster, more reliable, and overall far superior"

sounds pretty biased to me

NovakTwo

Are you saying that the statement is incorrect?

No what I think he is saying is when Novak says that the sensored feedback system is "far superior", that in other words is saying that's it's better.
I like Novaks gear; it's some of the best stuff out.

Faster, so software computation is slower than a wire transfer of info.
More reliable I've had 2 novak sensor harnesses failed out of the package with broken leads @ the connector.
Far superior...not an objective statement.

Not saying it's not true, but it is biased, as would be expected from any companies website.

NovakTwo

I challenged the comment upthread that our article said that Novak claimed "sensored is better".

Now a new charge is made that certain claims are biased. We also say:

Is this also biased? Is it untrue?

~McSmooth~

If Novak feels sensored motors are "far superior", then they should have little objection to allowing sensorless to compete in ROAR events. They would simply be able to dominate the competition, correct?

What better way to demonstrate their superiority than going head-to-head?

dude... face it... its a marketing article. theres nothing wrong with that. thats what companies do. they push their products. but trying to pass that off as a scientific comparison is just silly.
