brotherhobby is on my go for list next to xnova, i flew some tmotors in the past, actual i fly some f20 v1 1406 3200kv... i like them but they arent my first choice actual. the seems not as good on micro motors, their f15 was bad.
brotherhobby does competitive quality motors in all sizes, from x-class to 1103 they are on top, i dont see that by t-motor...

my superman 1404 was very nice but they didnt last to long

i didnt saw trust data for the iflight motor, it seems in the same weight are but have higher max current, maybe its also more powerfull too? awaiting your impressions :-)

brotherhobby did 1404 motors years befor they get popular :-)

they have a new model, maybe the size you like and know would be a good comparison about bh as brand?

as you like t-motor smoothness, you should feel at home on bh motors :-)

What happened to the Superman's? I've put mine through the paces and it just keeps going. But I hate the 9x12 mounting pattern on mine. Yea, Tmotor has had some bad press lately too with I think someone finding Velox (low end) innards in a Black Bird motor which cost a little less than a left kidney.

As for the Xings, I'm expecting typical iFlight super notchiness which evidently is torque or something like that? Personally I love smooth - just something about the flight characteristics. And the BH VY's are crazy smooth. But I still do think they are budget motors - maybe not Emax Eco budget but def not in the same class as Tmotor. It's funny I think XNova is even more budget dude LOL.

Also I checked my build after tuning and noticed ALL the stack screws were very loose. Clearly not so loose that everything flew off. But way more loose than I normally have it. I also noticed the balance lead off the lipo was not fully secure in flight. My filtered gyro was clean but I did notice some noise in gyro scaled. Maybe it was this causing some noise enough to push the BH motors too much at such aggressive filtering and high D.

they worked for nicely, but one after the other windings got "burned", i had 5 pieces after replace the first - a flight later the next died, while troubleshoot the third. it wasnt "hot" flights when they quitted.

xnovas work under high performance for long time, they are durable can handle a lot heat. they change their color from red into pink overtime from excessive heat xD they arent smooth.
they would have some 1404 motors too xD why did you an to the conclusion of budget product?

the vy are ultralight motors are more weak for the benefits of low weight. a t-motor f20 II is different there, but brotherhobby other motorlines like the tornados 1407 II fit the same needs.

emax motors does all seem like budget motors to me, not just the ones written eco on it :-) i use some rs1306 4000kv from them and like them

I'm just going by feedback from others regarding the Xnovas and BHs as "budget" motors.

If those Supermans burning out were not too long ago, you should get with Nguyen at Airblade. He's super chill and will probably help you out - and he'll want to know about this too.

The Xing's should arrive today. Those will replace the T-Motor 1404s on my red Ronin build which is now transplanted into a older prototype Mk2 frame. Very excited to see how it flies and compare to the BHs. But I don't think I'll be able to get some tuning in until the weekend.

I'm a total noob, guys.  It was the loose stack screws causing the problems.  Everything is bolted down now and these motors are barely running warm pushed *VERY* hard at D=40 and minimal filtering.  Happy days  

... not so much for the Xings though.      Don't get me wrong, they are actually impressive motors - not notchy at all like what I've seen in all other Xing motors I've used.  Kinda surprised me actually.  But my noobness struck again when I used screws that were too long and insisted they were not touching the coils.  They were.  You know what it's like to take a lighter to $30 cash?  I do.  

But i've since gotten them replaced (yes, I did it twice.  Thanks for noticing that.  Why don't you give me a paper cut now and pour lemon juice on it.     ) and ... well, now the thing just falls out of the sky whenever I punch the throttle LOL.  I know ... when my noobness strikes, it strikes like something fierce LOL.  

oh nooo

nice you got full performance out of the bh :-)

Yea I think there's something wrong with the FC which is super annoying.  Checked BLHeli for any errant ESC settings, tried turning off bidirectional Dshot, even tried reflashing firmware from scratch and still it cuts power to the motors on the slightest bit of throttle blip.  I'm going to try swapping out the motors to rule that last bit out then I'll have to swap out the FC.  Either way, it's gonna suck.  

Ok so now I'm re-thinking the 1404s on my sub250 long range builds. I'm using 4S and 2800KV to good effect. But I'm wondering if it might some efficiency gains with a bigger motor. But should I go 1505 or 1407? I'm not aiming for higher performance but for better cruising efficiency. What do you guys think?

i bet, wider stator does match efficiency better. high stator does give nice response but cost efficiency.
if you choose a high stator, higher pitch might work better, for wide stator low pitch should be most efficiency.
ecalc could do better suggestions than me :-) ecalc.ch i believe it will give a good route

Yea I'm allergic to ecalc lol.  1505s it is.  I trust you hugs!    

In all seriousness, I think you are right from some further researching.  I also ran the numbers.  I've been tracking the weight of every single electronics, screw, standoff, bits and parts so I have a little database now to come up with reasonably precise AUW predictions.  I'm going with Toka 1505 2650KV specifically.  And if my maths is ok, I should still be good to use the GNB 4S 1100mAh lipos.  If my maths is ok, I should have about 10g to spare but I do plan to use a lot more TPU than a freestyle build to hold the antennas and GPS. 

I am aiming to make a proper LR build but just micro / sub250 with a bottom slung lipo and GPS mast, etc.  All that TPU is gonna add up.  But at least no need for landing skids which is surprisingly heavy.

a buddy fly the 1505 toka motors with 2650kv on 6s and 4inch, it flys very nice.
his build is ultralight, but could ask him for a flighttime test on 4s if you like
