Nanolongrange V2 GPS FPV drone with single 18650

thingiverse

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: - <a href="https://www.banggood.com/custlink/G3KhOJpuoD">Happymodel DiamondF4 AIO</a> - <a href="https://www.banggood.com/custlink/KDmYLrCwjy">Flywoo Robo 1202.5 11500kv</a> - <a href="https://www.banggood.com/custlink/m3KRtE4DZy">Gemfan 3018 props</a> - <a href="https://www.banggood.com/custlink/vmmd9kpYDF">Beitian BN-180</a> - <a href="https://www.banggood.com/custlink/DmKYCzyirZ">Caddx Ant</a> - Longrange RC System like Crossfire, Tracer, ELRS... I used ImmersionRC Ghost - 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. Third, using an omni-directional antenna brings a cleaner FPV feed. However, you need to desolder the monopole copper antenna and solder the omni antenna directly on the FC. I also tried a step up module. It brings some interference into the FPV feed but ensures that the VTX keeps a high output at a low battery voltage. In addition, I ve tested its freestyle capabilities and a 21700 battery (Samsung INR21700). I also designed a new version of the frame. It allows for standard sized tinywhoop AIO boards. A cheap solution is <a href="https://www.banggood.com/custlink/mKmytd6G5c">Jhemcu Play F4</a> There is also more space to use an external VTX like <a href="https://www.banggood.com/custlink/GvDdo9Z4D0">IRC Tramp nano</a> with <a href="https://www.banggood.com/custlink/GKGEaIIB3f">step up module</a> The frame comes in under 10g (PLA+) as it is beefier. Therefore, I call it NanolongrangeV2b(beefy). Update 2: Nanolongrange V2b allows you to use standard sized tinywhoop boards and an external VTX with a step up module. On +500mW FPV range is no issue anymore. I strongly recommend you to print the frame with PETG, it is very robust although slightly heavier than PLA+ (2g). The best GPS for this drone is in my opinion from a Gopro (I have tested Beitian 180 and 220 as well as a small Goteck) which can be salvaged from broken Hero 6,7 and 8 cameras. Finally, make sure that the cut off voltage of the step up module is well below 3V!!!
