The story behind the build

I always try to make my builds as noisefree as possible to tune the BF filters and PIDs.
Sometimes it's not just for the flight performance but as a challenge.
So it was no question to build one quad with the most engineered frame in this aspect, the AOS.
I just wanted to wait for the second version because I believe in evolution :)

With this build I also wanted to realise a long-cherished wish to connect all (main)components pluggable.

Choice of components

Ok, the frame was set.
I am a big fan of the Xing2 motors, therefore no discussions... Size? I prefer 2207.
I also became a fan of the Holybro stuff, especially the ESCs. For FCs I follow the rule more power is better -> Holybro H7 stack
For the videosystem digital was set anyway. But I like the DJI Air Unit because I like the look, its rocksolid and it has sound recording which I find very helpful for tuning (I use no Gopro or something else).
The Azure Vanover are proofed by myself and I have less vibrations than with the most other brands.
For the VTX antenna I think the AXII is one of the best, although it is a bit bulky.
According to Chris Rossers doctrine, damping grease is a must have. I wasn't able to get some of this NyoGel type, but I got some Rocol Kilopoise 0868S which turned out to have at least a mensurable effect.

Building

I love the concept of this frame an really enjoyed the build.
But I don't like to fix things with double-sided adhesive tape, cable ties or something along those lines so it was a challenge to get the Air Unit into the frame.
To put the stack to the front or rear also was no option for me, so I got some headache....
I modified the Air Unit to fix it with screws, but the length was a problem. Finally I made it and nothing touches the FC directly, but the clearance between Air Unit and FC is less than 2 mm.
The concept of the pluggable components also worked, so I was very happy with the result.
It's a bit more messy than I expected but i'm ok with this - the goal was not to build the prettiest quad ever but an innovativ one.

Flight quality

I pre-tuned the filters according to Chris's recommendations: How to tune Betaflight 4.3 PIDs and Feedforward like a MAD SCIENTIST! Featuring the AOS 5 V2
and turned the masterslider to 1.5 for now. This setup is not at the edge, but the quad flies very good and stable!
I put a noisplot for the gyro scaled roll into the photos, this is a flight of app. 2:30 minutes with a lot of fullthottle, flips and rolls.
This build really has the potential to get my best flying quad!
