Default kV ratings of the .5 brushless motors

I can't find any kind of info on these at all.

what's the unloaded kV ratings of the newer brushless motors? like the 13.5, 10.5, 9.5, etc

I looked at that already but I figured that only applies to novak motors.

Am I to assume that those ratings apply to all the .5 motors coming out, novak and otherwise?

Nope.

The KV rating depends on the size and design as well as the number of turns. For example, I am running a 2.5 turn motor in my 1/8th scale electric conversion, but it is only rated at a KV of about 2000. A 2.5 turn in a Novak motor size and design might be as much as 12000 KV.

and I think that shows a problem. I can't determine how fast a motor is using the .5 ratings. If they stuck with kv ratings I could know exactly what i'm getting instead of going '7.5 what?'

All of the Novak KV ratings are given here:

Like someone else mentioned, KV is a function of motor design and setup... so these numbers will vary from manufacturer to manufacture.

If you do not have a Novak motor, I suggest contacting the manufacturer for for your motor's specifications... and see if they have any info for you.
