1130g with a 3-stage paint
Found a picture in the thread showing 1018gr with normal paintjob so 100gr extra. With uhd hanger and bottle cage screws.

Whats the hole under the hanger used for?

Also, the hardware included a thin metallic washer. Where is that used?

Not sure about the hole under than hanger, but that thin washer I beleive is used to interface the fork/steer tube and the lower bearing in the headtube.  But without a picture you could be referring to something different.  Also I'm just going off memory from my build.

Got my frame in the mail this week, built it up and took it out for the first ride.  I built it up with SRAM red XPLR and XMCS bars.

The build process was the smoothest I've had for a Chinese frame so far.  Others I've built up are: Speeder SC-55RD, Onirii One, Velobuild AreoGrav, and a Yoeleo rim brake frame a while back. In general the parts included were just slightly higher quality than most.  The headset bearings come in their CEMA box, the expander plug seems nicer than others I've gotten and the thru axles are on the lighter end compared to others (I think they weigh the same as the Onirii and 10g less than Speeder, not that 10g matters but to me indicates they are paying attention to details). 

The only issue with the frame I had was super minor.  The drive side of the bottom bracket was very difficult to get the threads engaged.  It would have been really easy to cross thread if I just forced it.  Once the first few threads engaged it went in smooth.  The other side went in butter smooth, so not sure what the problem was.  Fork has the brake cable come out on the left hand side, which is good for routing the non-UK way but might be annoying if you want your front brake on the right (I assume there isn't an alternate fork).  Brake mounts seemed faced and aligning the capipers was slightly harder than the Speeder but easier than everything else, including my old Canyon Aeroad.

Handle bars so far seem great.  Super stiff.  Geometry seems good and they now have those little bumps on the tops for grip and a nice XMCS logo in front. 

I've only ridden it for 30 miles so far so can't give a complete opinion on the ride feel, but will say general impressions.  Compared to the Speeder and Aeroad it is way less harsh and much smoother.  It also feels a bit smoother than the Velobuild AeroGrav.  Compared to the Onirii it's similarly comfortable but feels much stiffer.  The Onirii is a bit of a noodle and this bike is not.  In terms of handling, for me it's the best I've had.  It's not twitchy or super racy but it I would and will race a crit on it and I won't be wanting for more.  For me it handles like the like the Canyon but less twitch and more stable.  The speeder for me just doesn't handle well because I have to add a ton of spacers + positive angle stem so it's feels unstable.  In terms of stiffness/repesponsiveness I haven't really done any sprinting to test but it feels rock solid.  On the flat/downhill it feels a bit more sluggish than the Aeroad and Speeder, probably the longer chainstays.  Uphill it feels really good out of the saddle.  Just seems to go when you put the power down.  That's probably due to it being lighter but just as stiff in the rear compared to my old Canyon. 

To summarize: to me it feels like the Aeroad but more comfortable, lighter, more stable, and a tad less twitchy.  Once I put some more miles I can give more in depth opinions.  This is just based on one ride so subject to change, but I really like the bike so far

The frame seems to be inspired by the Ridley ASTR RS.  The geometry is nearly identical
