This is the Super 75x frame available from AirbladeUAV.com.

37.4g as pictured without lipo.

It's intented to be an easy swap for the eletronics on either a Beta 75x or the Mobula 7. It has mounting holes for 11xx and 0x0x.
Mine is a custom build, but is most similar to a beta 75x conversion.

The RotorX 1835 props barely fit and wire management is critical on this build if you use them. I also had to trim the canopy quite a bit to clear the props. 40mm whoop props fit without any clearance issues, but the rotorX props are so smooth, quiet, thrusty and efficient that I recommend the extra effort to fit them.
The pictures make it appear I mounted the VTX underneath the FC and the buzzer on top. For the final build, they actually swapped positions as I was able to save about 0.6g in wiring by making the VTX wiring harness much shorter.

You can expect excellent flight times with this build. I can get over 4 minutes of cruising, and 3:00-3:30 of hard flying.

I used the BetaFPV Beta 85X EOS2 mount because it fits betaFPV canopies (one is included with the frame) and is very durable when printed in TPU. STL files are here: https://betafpv.freshdesk.com/support/solutions/articles/27000053350-stl-file-for-eos2-camera-mount-25-45-switchable-
