Why is the flight time at 40km/h roughly 1.4 times hovering time? One would expect drag reduces the efficiency...

#22Flying in VR is not good for motion sickness.
It's not VR it's just like a normal screen strapped to your face (it's a simple image not stereo like VR does).

It's the same thing with helicopters, they need more power to hover than to fly forwards. It's called translational lift. https://en.wikipedia.org/wiki/Translational_lift

Not sure why downvoted. But it’s true, it’s not for everyone. I love my oculus but I can only play games in which I am stationary (my character doesn’t move unless I move in the real world) It’s a shame because this looks fantastic but I probably won’t be able to use it without getting motion sickness almost immediately.
It's not VR (no stereo image) it's just an easy portable way to have a big screen.

#25There has been a huge divide in the drone world between high performance first person view (FPV) drones capable of acrobatics and the "tripod in the sky" type drones that companies like DJI have popularized. The former has been very DIY and the latter have attracted companies to build integrated solutions. This new drone from DJI brings an truly staggering amount of innovation and integration to the FPV space: - Low…
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

#2650Mbit, 28ms latency wireless link at 12km distance, and on a battery budget, eh? I'd love to hear more, I love science fiction.
Ocusync has been out for some time now and it already sounds like magic. I think when compared to wifi or some radio bridges it usually operates in much less congested environment. Nonetheless, if you think about frequencies used, energy going down with r^2 and bandwidth they are doing, it's an amazing feat even in ideal conditions. And here's it's a moving object, on battery, with four electromagnets around it.

To be fair, hovering time is often lower than flight time for copters.
Re: DJI FPV
#28Awesome controls, although a little disappointed in the image quality. Hoping for a v2 of this
What of the image quality disappoints you? The example footage looked great to me, and 4k@60fps is the main thing missing from Mavic 2 that I wish it had.
Re: DJI FPV
#29That’s impressive. I’m not sure I understand how you can still communicate and see the video feed even when the drone is far away.

There are various FPV groups on Facebook, and Joshua Bardwell shares a lot of knowledge on YouTube. Also, prepare to lose a lot of your life soldering things.
