I mainly fly micros, from 3" to something as small as 1S brushless micro, wanted to make some nice HD video when I fly outdoors but action cams are too heavy for micros.

What I was looking for is something small-ish, top mounted battery, equipped with Runcam Split/2 and no props in HD footage, nothing out there really suited my needs, I decided to make my own. From paper draft to 3D CAD model, ended up not so micro, 155mm motor to motor diagonally for a true X 3" setup.

~Got the frame made and I built the rest, waiting for maiden, unfortunately didn't see any daylight in my free time for the last few weeks (maybe months), it might need to wait a while... :(~

Nope, not exactly performance-oriented design.
Yes, camera is at somewhat unusual position and less protected and yes, I broke the lens, gotta update camera mount design...

Looks good! Whats the total weight without battery? Also, whats the weight of the frame components?

211g without battery in the pictured configuration, the extra weight of 4mm plate offers no real benefit IMO so I've discontinued it

leaving 3mm true X the only "set" configuration for now, dry frame with hardware approx. 52g

also price dropped to match similar frames in the market if you're interested

looks cool! A 4in version would be fucking awesome!

That would need to enlarge the middle section of the frame quite a bit to keep props out of HD footage, or turn it into Wide X to keep the current body size.

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

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..
