BlackMagic Hexa

The purpose of this frame is to allow us to fly a cinema oriented camera in more of an FPV manner (close proximity, dives, high speed ...).

Everything is custom built: frame, crash cage, silicon mesh. The design was done by Octavia Richea.

Flight time is 6-7 minutes at normal pace and will go down to just a couple of minutes if pushed. The PDB cannot sustain the 6 motors being pushed to max for too long which is why we exercise caution when flying it in order not to fry the PDB. These motors can easily go to 45-50A in full throttle, we've tested them on the bench.

It has a video switcher which allows the pilot to see what any of the two cameras sees. The latency of the blackmagic composite video output is minimal which makes it flyable in FPV mode.

We have a second receiver onboard to allow the camera operator to adjust all camera settings while flying.

Nice build. What UART on your F7 board did you wire the Crossfile receiver to? I can't get any response from mine, connected to UART 2.

Edit: I figured it out.... had TX/RX swapped. :)

You know you are doing something right if you are concerned youll over amp a kamakazi matril insanity pdb...

painfpv   May 23, 2018  

and here is a 422 prores sample from the same flight test. keep in mind that this was with stock PIDs under very windy conditions. also note that although the lens is a 7.5mm the crop factor on the bm cameras is ~2.88 which makes it a ~22mm lens which is not very wide.

untill I can process some of the footage, if you are curios to see how live telemetry looks like on this setup here's a quick video from the very first flight with it:

Hey Paul,
In the description you mention you have a video switcher so you can switch between the BlackMagic and the RunCam.
I recently bought a BMPCC and was thinking about getting it on a large fpv drone too, what hardware are you using to switch video?

painfpv   May 23, 2018 

I bought it 4-5 years ago :) and can't find the exact product anymore but it is very similar to the one I've linked below, might be exactly this one without the nice paper wrapping: https://hobbyking.com/en_us/hobbyking-3-channel-fpv-video-switcher.html?___store=en_us

skjb93   May 23, 2018 

Thanks. That product seems pretty straight forward, how did you get the BMMCC connected to it though?

painfpv   May 23, 2018 

I've powered it from a 12V regulator, connected it via SBUS to my second receiver and connected the video composite to the video switcher. here is a pinout but you also have the pinout on the box it comes with. https://i.imgur.com/1Bhckiw.jpg

wouldnt be suprised

CaptainFalcon   May 23, 2018  

I'll jump on this bandwagon.... WE NEED VIDEO!!!

painfpv   May 23, 2018  

I've posted updates regarding this setup, including some video results, on this facebook group: https://www.facebook.com/groups/1551618814932503/?ref=br_rs

I will also upload the results on youtube or vimeo and link them here when I have a bit of spare time.

I suppose you're required to include flight footage from the BM camera when you post awesome builds like this.😆

I will add footage in the description and let you know here. :)

Whoa! This is the first copter I've seen using Blackmagic's Micro Cinema! Kudos... I'd love to see a video of this guy in action.

Whiffles   May 22, 2018  

I'd love to see some footage from this. Anything published?

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..
