XZING or DONG

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.

"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"

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 .

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.

ADD 5% to manufacturing cost and 5% for material cost . boes not justify price hike.
I have and fly xzing motors znd the 2 pice bell is seperaitingon on some.

im not going after anyone just pointing out that a cotton shirt costs far less than a silk shirt manufacturing costs same .
Yes silk is more costly but not enough raw material is used to really impact on final cost
If you can grasp that.

sorry sarcasm not needed

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.

lol no problem, its all good :) I'm a believer in 'if it works, just fly' so sticktime>gear

A couple years ago I built the TransTEC Frog and since then I've been patiently waiting for another TransTEC frame to catch my eye. Fast forward to today and the TransTEC Laser S is that frame. It's a 82g racing frame that features 6mm arms, a TPU micro cam mount, 30.5mm and 20mm stack mounts and 3K carbon and 7075 hardware. My goal here was to build a high quality 6S racer at a reasonable price. I'd..

This is the 4th installment to my popular "Wizard Killer" series, and is based on the popular Wizard X220HV 6S. As usual, the goal was to build a substantially better quad, yet come in below the retail price of the BNF kit. Here are some of the improvements: Higher quality EMAX ECO 2306 1700kv motors Foxeer's top-of-the-line Falkor mini camera Eachine 25mw-1000mw Leaf VTX with microphone Tools This..
