I was so annoyed by my long range wing that I wanted to build a quad.
This is my first build running EmuFlight. Even with that big battery it flies decently.

600g AUW (with props and gopro)
775g 4S4P 18650 10.4Ah

-> 1375g takeoff weight
~25min flight time

Edit 1 (18.12.2019):
Landed at 3.3V/cell (under load) after 20min.
I am going to try a 4S3P pack with 3500mAh cells to get the same capacity at almost 200g less weight.

That pack seems crazy, even to me - do you think there would be any utility in a lower weight (4S2P, 4S3P) setup for the same general idea?
I'd want to run a 4S1P pack up top, and 4S2P bottom mounted, and see what that could do, but that's new territory for me.

It flies with up a 5S8P 2kg battery but I'll soon be building a 4S3P with either VTC6 or Sanyo 3500mAh cells.

Nice. That just makes me want to go fly around with my 6S 5000mAh LiPO pack.

That pack is a beast! What cell are you using? I'm loving the benefits of Li-Ion so much that I'm trying to work on some smaller quads as well. If only there were high drain 18350 I could have a proper 2" Li-Ion build. Love the build as well!

I'm using Sony VTC 5 2600mAh.
Take a look at Dave_C FPV on YouTube. He is working on some cool longrange micros

Watching the micro long range video now. Very cool!

my goodness gracious, this is definitely a dream build for me... wow, well done!

Thank you! I started to plan and improve the component list almost half a year ago.

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..
