XZING or DONG
By kwadkenstine on Apr 11, 2019
Edit 12 june
This post has been misunderstood by some.
The objective was to compair 2 differently manufactured and labled motors and compair thrust at about 66% throttle , hence the 1700 point setting in motors tab in bf. I was not surprised they were different .I was surprised at how close they appeard to be. .
Make of this what you like.
Motors
XZING 2306 2450kv.
DONGXINGWEI 2306 2700kv.
Both motors run up to 1700 in betaflight motors tab . D SHOT 600 .
4S BATTERY.
XZING drew 18.1 amps at time of photo.
DONG drew 19.4 amps at time of photo.
Props dal cyclone 5046.
The xzing motors are smooth smooth smoooooth.
The others sound like cement mixers.
DONG $43.00 australian dollers for 4 free delivery.
XZING $24.00 australian dollars EACH.
KV is a meaningless useless number.
Motors should be marked output in wats per gram motor weight/voltage.
Or something like.
For me i love the xzing but i live in ironore country where it doesnt rain.
Even landing gently fills the motors with iron rust and heamotite.
Yes it blew me away when i saw how close they were.
Edit.
For those fans of kv jargan ,please concider this.
KV is only a number.
rpm per applied volt with no load..
So a 300kv motor spins at 300rpm at 1 volt.
Where is that voltage measured from.
the battery or the esc output.
If the output of a esc is different from others in any way the numbers become dificult to compare.
Lght or heavy bells change kv.
motor output is not linear . what voltage and esc settings were used by the manufacturer ..
Rpm and applied voltage is not enough information to be quantifiable.
A third point of refrence is needed. Just like radio triangulation. Without 3 points of refrence a location can not be calculaited in 3d..
Dont be fooled by claims of kv.
And from The research ive done it seems that reviewers of the xing motors feel they behave like motors with higher kv.
Heavy bell = lower kv .
So the 2450 behave in the air like a 2650..
IS this a lie???
DOES IT MATTER.
Durability , so far not an issue with xing or dong . im going to smash them before they ware out.
I have only one set of xing and 5 quads sporting the dongs .
no failures on any of them xing or dong.

For me the difference is in the durability of the xing motors. Cheaper motors all too often have shit bearings or don't hold up in crashes, so I end up having to buy 2 or 3 extra more to get 4 that will work for more than 20 packs. I have found that I end up spending more with cheaper motors in the long run.
Fascinating!
true to an extent but I feel (and a lot of us will know first hand) that different levels of quality and lifespan exist and are very real. not to say someone or a small group won't have their cheap motors last years, they definitely do but on average, not so much. again, some bits are, agreed, way overhyped
I am in no way am having a go at anyone . I appoligise if it seemed that way. But the naming convention motor promotors use can be fiddled. No doubt quallity costs. But really the only diference between the motors is the xzing has a o ring and a hex bolt to retain the bell and give the bearings some pree load and possibly better bearings. but i find the price difference hard to swollow.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

"KV is a meaningless useless number." This makes no sense at all... First of all the KV is a very important number... You are testing 2 motors at different KV's and are surprised when one does better? Your thrust testing isnt even correct because these motors can output far more than 1KG of thrust so right off the bat all of this information is invalid. I've used low cost motors and high cost motors, high cost motors last longer, have better bearings, nicer windings, stronger magnets and better overall construction quality making them more durable. The XING motors are very well priced for how they perform and the feature set they have. Just so you know they are XING not "xzing"
look up miniquad testbench read the post properly and get an education
no sesce of humior eigther
sense humor either* lmao
Picking on a persons spelling is a low blow
maybe you should use www.dictionary.com and get an education
cant cure dyslexia . please dude have a good think about kv and what it actually tells you about a motor.
my statement may have been a bit strong but it is still true .ask someone else who you trust not your mates.
i dont want a clash .
