So the motors are quite nice, they do have temp sensors that my previous flipsky 6374 that it doesn’t have.
I don’t particularly feel a difference, perhaps a bit smoother with those curved magnets.
But I really like their look that goes quite well with my motor mounts.
I think when they turn, they are “smoother” than other motors.
@CiscoV extra speed
Ah. Ok. That’s what I thought but didn’t want to jump into conclusions
Looks nice 
That’s what the magnets would do: less cogging torque so easier coasting but at the expense of getting a bit hotter for same output power
Last flipsky motors i took apart the stator inside was smaller than you’d think. But almost the whole motor performance can be summed up and compared with ANY other motor looking at the kv and electrical resistance. Other than that the stator laminations can be a variable in performance but pretty small in our slow turning use.
Other than that it’s a comparison of the mechanical aspects and if bearings are tightly fitted. Or motor balanced. Or won’t fall apart.
That tail fin is awesome.
Yes. I have (1st week in March.) Shipping was $28 DHL on 2 motors. I got them in a week here in Cali SF Bay Area.
I was just looking at these up close on their site.
looks like this new can has a single retention screw to hold the motor can to the motor shaft. This looks like a failure area to me for sure. They use the same bevel inside the can as many other companies to increase the area of contact with the shaft, but a single retention screw will probably be a weak link for this can. At least that’s what my TB motor experience has shown – and there’s whole threads dedicated to this
There are two, but they are 180° offset, so may as well be one.
ahh good to know, couldnt see them in the drawings. Next time theyre apart take some pics
getting some interest in a gb for these motors
I have been waiting on a 2020 v2 antispark for just over 30 days. There is a USPS shipping label, but they are still waiting for it to arrive in-country.
Magnets definitely installed the wrong way. 
What do you mean?
Should they not be facing the other way and be concave in as opposed to concave out?
No, the convex shape is intentional.
It has less detent and lower noise because the magnet field is more uniform.
Got it, I always thought it looked backwards but didn’t know why.
Don’t you lose some strength though? I get the fact that it’s more uniform which translates to less cogging (right?) but there’s more distance between the stator and magnets now right?
Yes it has a higher Kv because the peak magnetic flux is lower.
Oh wow. I always thought that the curvedagnets are preferred because when installed with the concave side facing in they reduce the airgap and increase the efficiency.
Yeah this has always been my assumption too. I would have guess less detent/cogging could be dealt with small angled magnets or more magnets so you don’t sacrifice the airgap and efficiency
@rosco your previous question answered by someone who does know what they’re talking about ^
the magnets that way will likely make the motor less efficient as the magnet is further away from the stator. Maybe if it was a 200kv motor with normal magnets and then they switched to those convex magnets maybe it would go to 250kv…and then you’d have to do another turn of wire on the stator side to get back down to 200kv, and that requires thinner wire and more electrical resistance and bit more heat.
but will produce less cogging and cogging torque, so coast easier.
then again it could produce less “noise” having a more sine shaped magnetic field produced that would pair better with the stator and have less losses in that way.
