I saw this interesting 1S 3-inch FPV drone using 18650 Li-Ion cell for long range, and I had to give it a try. I will share my rather unsuccessful attempt and what you can learn from my experience if you want to build this too.

Li-Ion cells such as 18650 or 21700 have higher energy density than LiPo (more capacity mAh for the same weight), they make great battery for long range flying. I will recommend what to buy, and also show you how I built a 4S 18650 Li-Ion battery from scratch.
Field of view (FOV) is an important consideration when buying FPV goggles, but FOV is not something easily comprehensible. That’s why I created this tool to help you compare screen size of goggles with different FOV side by side.
Even if your motors KV are for 4S LiPo (for example 2208 2500KV), you can still put a 6S LiPo on your quad. This is a new feature in Betaflight that auto adjust motor output to compensate for the voltage difference.
LQ and RSSI can be confusing for first time TBS Crossfire users. I will try to explain the differences between LQ and RSSI for Crossfire. I will also show you how to set it up in Betaflight and OpenTX to monitor your link quality and range.
Minimizing the radio control latency can improve flight performance of the FPV drone, as well as giving the pilot more confidence and faster response. In this post I will explain how to reduce RC link latency as well as the considerations.
GPS Rescue mode in Betaflight is similar to “Return to Home” on a DJI drone. It is meant to help bail you out when your video feed or radio signal gets sketchy, the quad is supposed to return to you automatically using GPS.
DJI FPV footage has an aspect ratio of 4:3, and it leaves two massive black bars on the sides of the screen on Youtube. I will show you how to create 16:9 Superview for DJI FPV footage in Davinci Resolve :)
You can build a working GoPro Hero 6 with spare parts and it might be cheaper than buying the whole camera. If you want a naked GoPro this is way more convenient as you won’t have to spend time taking the camera apart.
The Radiomaster TX16S is a great radio, but you can’t remove/swap/upgrade the antenna for the internal multiprotocol module. In this tutorial, I modified my TX16S with a SMA pigtail so it has a removable antenna.
Here is information regarding “naked” GoPro Hero 8 camera – a stripped down GoPro 8 can have the weigh reduced from 126g to only 15g.
