Lipo batteries degrade over time, sometimes this degradation results in dead cells. It seems to be a waste to throw the whole pack away because other cells might still be working. In this post we will show you how to make a working LiPo by combining the good cells from multiple damaged/defective batteries.
The Fatshark battery case is a convenient holder for 18650 cells. However it’s not designed for charging, and you have to take the 18650 batteries out of the case to charge them. It’s quite annoying so I decided to modify the case so that I can plug it straight into the charger for charging.
Buzzer can help you locate your crashed drone, but typically it won’t work if the battery is disconnected in the crash. Here we will show you how to build a DIY lost model alarm with its own little built-in battery.

We all know bigger FOV gives you “bigger screens”, but how much bigger? In this short post we are going to find out. I also made a handy tool to let you quickly compare the FOV between two sets of goggles side by side. It’s scary what a strong cup of coffee can do to you :D
More and more top pilots are posting cinematically edited long range FPV videos of mountain dives, flying across rivers or sweeping over villages. The sense of exploration in these videos is truly amazing, and reminds me of what got me interested in FPV in the beginning, to explore!
Does ND filter on GoPro cameras actually remove jello and make your FPV videos look more cinematic? We are going to find out in this post, and I will also explain what an ND filter is, and how ND filter affect GoPro image quality.
I tested some high KV motors with 6S and the result is pretty interesting. Generally it’s recommended to use low KV motors around 1700KV for 6S and 5″ propellers. But when I first heard the idea of using high KV motors on 6S I was a bit skeptical so I decided to find out for myself :)
Charging LiPo batteries in the field is an excellent way to let you fly for longer. I will share my field charging solution which I believe is better than buying more LiPo batteries in many aspects.
LQ and RSSI can be confusing for first time TBS Crossfire users. In this tutorial I will try to explain what the differences are between LQ and RSSI in Crossfire. I will also show you how to set it up in Betaflight and OpenTX on the Taranis TX to monitor your link quality and range.
