First micro build and it turned out great! I wanted something that I could fly anywhere, fly aggresevly, and also let others try out and not have to worry about breaking when it crashes. I went with the Betafpv 1-2s 12a V2 aio w/ Expresslrs so I wouldnt have to buy an RX, and I'm also not a fan of integrated VTX's. If youre in US or Canada and want fast shipping I found the FC at AirbladeUAV.com and they worked really well with me. The first one I recieved would shake aggresevly along the yaw axis, so much that it was unflyable and ended up being because of a faulty gyro, after a week of intense troubleshooting I contacted airbladeUAV and they sent me a new one that works great now.
(sidenote this is my second build, the first being a 6s. plz excuse spelling errors:)

As far as the parts go everything works great! The antenna fits nicely ontop of the canopy and is secured well with a ziptie. The Larva X canopy canopy was a gamble but it fits great and sheilds the camera really well which was a priority for me since I plan on getting sendy with this. But be sure to have some extra spacers on hand to lift the canopy up a bit because the camera can get pressed to the vtx and will get hot if not given enough of a buffer. I like the rush tiny tank vtx but it likes to set itself into pitmode, but youtube has the answers for that. Soldering the Camera directly through the vtx ended up being easier than through the FC and the signal range has been great. The baby ratel 2 camera is amazing and handles pretty well in lowlight which I thought I diddnt care for untill I had it and now I love night flying:).

The main reason I wanted to post the build is to put some info out there on this FC. Its not very user frendly out of the box and its relativly new so theres not alot of info out there, hopefully this helps somebody out:) (Ill put links to the websites at the bottom)
To bind Expresslrs I had to go to the express lrs website and search "spi recievers" , on that page it will let you type in your binding phrase and translate it into a cli command that you enter into betaflight and from there it should connect (no need to update the rx or even use the ELRS Configurator at all).
The other issue I ran into is Dshot wouldnt work if smart audio was enabled, I had to contact betafpv about it and they told me to enter "set dshot_bitbang = off" then "save" and that got it working.
The last thing is be sure to update the firmware to the newest version. I had some rx connection issues untill I did that and now its working flawlessly. The betafpv website shows the details for which firmware to download on the same page where you go to buy the FC, just scroll down and it has plenty of info (be sure to enable "show unstable releases" in betaflight and then you should be able to find the correct Target firmware.
Finally if youre getting some prop wash or wobbles on high throttle, the FPV Cycle reccomended PID tune for the Kebab babytooth build worked great for me and it flies amazing:)

I really love this build and am having a blast with it! It really lets you bang it around without breaking anything and still allows for some fun casual freestyle maneuvers
