Very nice build.
My current build is also a sourcemicro.
Do you have the models of the printed parts?

And what about the props? On my build, the 2.5" props are touching the standoffs...

For the moment I use 3 batteries 1S 300mah from Betafpv (which I already owned) while waiting to order 3S 450mah.

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
