Wu-Tank 6" Long Range FPV Drone Initial Flight Tests

I converted over my Wu-Tank 5" Long Range drone to a 6" long range drone and these are my initial first flights, thoughts, etc..
What I did was replace the Emax Eco 2004 3000kV motors I used for 3" 4s and installed Emax Eco 2004 2000kV motors, and then slapped on some Gemfan 6026 (6" 2.6" Pitch Bi Blade) props and test flew it on a 4s 4000mAh Li-Ion and a 6s 1300mAh LiPo to see the difference.
First flight was very short lasted less than a minute using the Li-Ion battery, the quad had very little power even with it being practically naked. However this might still be a very viable battery for taking this out on mid-long range flights.
Second flight was with a 1300mAh 6s Ovonic battery and I went for 5 minutes but had to stop as the 28 degree F (-2.2C) was killing my hands. That battery went from 4.1v down to 3.9v in 5 minutes which is awesome.
Third flight I was using a 1300mAh 6s CNHL battery that has been quite abused and is rather old. I got around 7 minutes of flight, with a DJI Action2 camera and the CNHL battery weighs about 30g more than the Ovonic battery.
Stay tuned for the flight time test!!

Great video! That DJI Action 2 Footage looks great. Super smooth

Yeah I really like the Action 2, I love the functionality, and the form factor. It's not Hero 10 or 11 quality but still pretty damn good, and tough as nails, and they are going to update it so that you can use gyroflow on the footage instead of the built in stabilization.

Nice one, im working on building a 6", do you think 1950kv motors would be ok?
