The GoPro Hero 9 is an awesome camera for FPV, but it’s heavy! By taking it apart and remove the unnecessary bits, you can reduce the weight from 158g to under 20g, even a small…

Unless you are super tech savvy, it’s almost impossible to fix a dead ESC. Anyway it wouldn’t hurt to learn how to test and troubleshoot bad ESC for common issues, and understand which component might…

Apart from tuning PID, you should also tune BLHeli settings on your ESC to achieve better flight performance with your FPV drone. In this article I will share my BLHeli_32 configurations that I use which…

By making Caddx Vista “naked”, you can shave almost 10 grams off your DJI FPV setup which is a huge flight performance boost to any micro FPV drone. I will talk about what a naked…

I will share tips and tricks on how to build and use the “naked” GoPro 8 – a stripped down GoPro Hero 8. You can reduce the weigh of the camera from 126g to only…

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…

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…

If you over-discharge Lipo batteries, you can end up with dead cells that read zero volt and cannot be re-charged again. In this post I documented how I repaired/fixed a LiPo battery by removing the…

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…

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…

We use low ESR capacitors in our drone to absorb voltage spikes, actually TVS diodes can achieve the same result sometimes even more effective.

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…
