Gotchas:
actually got Omnibus Nano v4.1 no longer available must remember to change motor 6 to motor 4 in resources. lol
Also installed Betaflight latest. 4.1.x oh my VTX tables.. https://intofpv.com/t-what-smartaudio-version-do-i-have so this vtx reports as 216 but actually is smartaudio 2.0
used metal screws for now till I get used to flying then might use plastic ones to save some weight as when using 850 lipo its over 250g but can squeeze under with a 650 lipo
update: he flew real smooth and quiet on 4" props with default betaflight pids. Put him on a diet, took out the antenna and replaced with a dipole, took out metal screws. Lost 26g! Here he is with 5" Props, well under <250g now with a 450 4S.

The "VTX report 216 = SA2.1" mentioned bij JB in the video is actually incorrect (some of the comments on YT already say so).
I'd suggest to use this as a reference for what version SA is on: https://intofpv.com/t-what-smartaudio-version-do-i-have (and still use the video as a guide on how to obtain the info and set the VTX tables).
