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.

Edit 2 (24.03.2020):
I upgraded a few parts and am mainly using it for freestyle flying:
FC: Matek F722-STD -> KISS FC V1
ESC: FETTec ESC 4in1 35A -> FETTec ESC 4in1 45A
Here are a few videos that were filmed with this quad:


(Beginning was filmed with a 10" Hex and the DVR was from my race quad)

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!

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

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..
