The finish of the motor looks very rough and the supplied bolts does not seem to be hex which became quite a standard for multi rotors.

It's a very small motor. Not a lot of hex heads on laptops, etc. Also, very rough? Seems like a very harsh standard for:

A) something that doesn't exist, it was invented
B) subminiature item, where finish doesn't improve performance
C) macro photos are usually put through a postproduction to eliminate flaws

Nice to see these small motors. Is RacerStar a Banggood exclusive brand btw?

What is landing :O
Would love to test the 1104 motors if possible with a new 160 frame build

Imagine I disagree with you.. I don't say your point of view is not correct, but
a rough surface means low quality machining or poor material.
In case of low quality machining - then it might be that the other manufacturing process is low on quality and might end in bad quality motor.

In case of low quality material - might be that the magnets are also low quality - thus the performance of the motors might be lower.

I have a bunch of motors worth nothing for which I have paid.

Update: I don't say this motors aren't good. Somebody will have to tell us. It is just the impression they give me for the first time.
Unfortunately I don't have anymore a suitable airframe for such size motors.

First you criticize the lack of hex head.

Your criticism makes no sense since M1.6 hex is more likely to strip, Needs a new tool, and its **not** a standard like you said.

You have no basis of opinion on the quality of the machining, because you're just looking at a photo. It's not jewelry it's one small brushless motor. There is no excess roughness in the picture, that's your imagination, IMO. Normal milling.

When Chinese manufacturers are innovating, and bringing new products to the market, it's a good thing. Spreading fear, uncertainty and doubt, especially when you don't even want the item, is unnecessarily negative.

maybe its meant to be that way, and it has a glitter coat. It does seem to look like that only where the light shines on it

To be fair, the other motors have a similar surface , its probably just the tinted red coating.

Worst case scenario is that theyre cast ( similar surface) rather than milled.

@BGJim, if you want you can send me some 1806's to play with i have a QAV250 frame getting ready for some fun, ground vs air

Interesting that the BR1104 4000kv thrust table shows 115gm with a 3020 prop on 2S, which is similar claimed thrust to a DYS 1104 5400kv, and the BR1104 has about a 35% higher efficiency at this thrust. It is also similar thrust to a DYS 1104 4000kv running on 3S. Plus the selling price is 20% lower. No mention of 3S so perhaps limited to 2S, which is fine for my purposes if these figures prove to be in the ballpark. Nice to see some more new motor designs.

I don't think my eyes are deceiving me when I see curved magnets on the 1103, in the drawing and the picture. If so, this is big news.

Let's see how it tests in the users hands.

Would prefer the 1104, these can be fit to my Tarot 130 for instance.

I would like to test the 1104 motors and can compare to the DYS 1104 motors
