Ez-wifibroadcast DIY HD FPV system based on ov5647 camera, Raspberry Pi Zero and high power AR9271 transmitter.
Will be running ardupilot on onmibus F4 V5, note the V5 has no built-in current sensor, hence 4in1 esc with current sense.
Expected runtime:+20min flight time on 160g 25c 2200mAh 3s zippy compacts (AUW 555g)
or +35min on 330g 5400mAh 3s2p Li-Ions (AUW 710g, similar to mavic)
XL8 arms modified to accept triangle bolt pattern.
Mini GPS replaced with BN880 M8N, as noise from nearby regulators made it unusable.

First tests
Zippy Compact 25c 2200mAh 3s
17minutes hover at 6A consumed 1600mAh (72% of 2200mAh).
Motors consumed an average of 64W (5.5A at 11.6V), efficiency 8.6 gramms per watt.
Other loads (Raspberry Pi, VTX etc.) 0.5A

BS-430 ESC current calibration result (calibrated at 6A):
BATT_AMP_OFFSET: -0.013
BATT_AMP_PERVLT: 25.639

Omnibus F4 V5 Vbat calibration result:
BATT_VOLT_MULT: 10.937

What flight times did you actually get?

150 meters isn't even as far as a 200mw vtx will get you... I'm thinking that's more like 25mw type range

Where can I see more about this video/telemetry system?! I'm following your builds now. This kind of experimenting and cobbling together unique systems and builds is my favorite thing on rotorbuilds. :)

I think 150 M for teh wireless card is not meters but the speed it can run at 150Mbps

How have you found flying with the raspberry pi camera? I ran a raspberry pi camera setup for a while, but with the analogue video out fed into a 5.8vtx. It was a wierd experience too much delay and the camera seemed effceted quite badly with the vibrations from the quad. Never got used to it so shelved the idea. This build has sparked my interest again cheers. Like the OSD.

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..
