DJI digital video has been out for quite awhile now for hobbyists to include in their custom builds. Transmission range is not a valid point because a clean analog video signal and Crossfire outpaces DJI enormously. The 20 min flight time is a lie, Joshua Bardwell measured 10 minutes hovering. That's extremely easy to surpass on typical light weight 5 inch freestyle drone with a 1300mah battery that cost a fifth of t…

You seem in the know, any recommended sources or communities I should look into, or even if you're happy to share more I'm keen to hear it

I got into it a few months ago Joshua Bardwell as the sibling mentioned is a great source of info: https://www.youtube.com/channel/UCX3eufnI7A2I7IkKHZn8KSQ

The main thing anyone starting needs to realize is that it takes quite a bit of time to get used to how Quads fly in Acro/Rate mode. I started on a simulator (Liftoff) with an XBox pad and that was super punishing as gentle and precise control is needed. Switching to a proper radio was a night and day difference. I'd guess it took 5-10 hours of flying time to get to the point where I could comfortably go where I wanted 99% of the time. I'm up to 50 hours of sim time now and flinging the things around with wild abandon. Looking forward to summer and getting out to try the real thing.

My recommendation for starting out would be to grab a cheap radio that is easy to connect to a PC and a copy of a simulator.

Holy sh*t that is amazing. I can't justify spending 1300EUR on it, unfortunately... :( I really like DJI and how innovative they have been in making awesome consumer products that just work and are super easy to use. I have owned a few.

Don't worry I think there'll be a big second hand market for these after people get cocky and switch flight modes and stack it into the ground. :)

Have you tested one? Video reviews are reporting at least 10-15m flight times in cold weather.

As you say at the end, this isn't a drone for racing. I think this drone would mostly be for videographers wanting to add FPV-style shots to their arsenal. I shoot with a Mavic 2 (https://serio.com.au/) and if there was a bit more of a market for the FPV look in the work I typically do, I'd grab one of these right away.

At this point though it's probably something I'd look at closer once I have a bit more spare time and can think about situations where it might be applied.

Uh? Can you explain this?

Given it's shooting 4k with a wide FOV, you could crop out the props. Most of the time with 4k, I am cropping and reframing anyway. In the past, my Mavic props have occasionally been in view too.

If you have leftover charge after you land it means you could have used a smaller (and thus lighter) battery, which would have let you fly faster.

Presumably not literally like in the case of a rocket or formula 1, but also literally as in, I could have used a lighter battery with less charge that goes faster

As I said, 10-15 minutes seems completely realistic when talking about the sensor stabilized and comparatively slow flight modes.

Most FPV channels that were reporting on the DJI FPV drone and actually tested the completely manual flight mode (which is the only one that really compares to the FPV flying you see in many videos) got around 3-5 minutes out of the battery.

And again, it makes sense when looking at freestyle maneuvers and how much power they require.

I’d love for someone to build an overIP bridge for this, so I can sit on the couch at home and fly through the Grand Canyon.

I’d happily pay a reasonable sum for it. I wonder if it could be done using a Stadia controller and chrome cast?
