Nanolongrange V2 GPS FPV drone with single 18650

Here is the improved version of my Nanolongrange FPV drone frame. Main advantages over V1 are
- 18650 and 21700 battery capable
- lighter (<95g AUW)
- GPS

Build:
The frame is based on the currently lightest available Whoop AIO board which need to be used due to its smaller form factor. The build is a bit more difficult as you need to solder! Moreover, the solder pads are quite small so you need a steady hand. The video shows all the building steps.

Parts used:

- 3x 6mm and 10x 4mm M2 screws (I used Titanium to save around 1g over steel)
- rubber bands

Update:
After extensive testing I can provide you with more information on my Nanolongrange V2 design. Therefore, I've created a video with testing, tips and tricks. First of all, make sure you got the VTX settings right if you experience a short FPV range (if your local regulations allow). Second, a higher VTX output interferes with the GPS. Thus, power up via USB to get a quick fix and reposition the GPS module on the frame.…
