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)
