SMA (RP-SMA), MMCX and U.FL are the three main types of connector used in FPV transmitters, receivers and antennas. The many types of connector can be confusing for beginners.  In this guide I will explain…

I just bought a MacBook and have done some research on which model is best for me. In this article I will explain why the 14-inch MacBook Pro M1 (2021) is a better purchase than…

My 4-year-old Logitech G Pro gaming mouse started giving me random double clicking on the left button. It’s a common issue but took me quite a while to find a real fix, which is to…

I have been testing FPV camera latency independently and I share the results here. Latency has an impact on the pilot’s reaction time and stick feel, and it is one of the most important aspects…

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…

This post explains how I built my FPV display, a great tool for bench testing, and it lets others watch your flying in the field. This project requires 3D printing, some cheap components and basic…

Capacitors can make your FPV video signal cleaner, and your mini quad fly better. In this tutorial we will explain what types of low ESR capacitor you should get and why low ESR is important, and…

Are you having trouble with motor outputs on a flight controller? One of the motors just doesn’t spin when you arm the quad? In this post I will share some experience how to troubleshoot and…

You can prolong the life of electronics in an FPV drone with waterproofing, the most common method is Conformal coating. It helps prevent components from moisture and chemical damage when flying in extreme conditions.

I had a power problem with the Taranis external module bay, it took a while, but it was fixed at last. I want to share this adventure of troubleshooting as it was quite a great learning…

This post shows you how to program ATtiny 85 and 45 micro controllers using the Arduino as an ISP. I also explain the advantages of using Attiny chip over Arduino for DIY projects. 

The inevitable question for RC hobbyists is how to get rid of old and damaged LiPo. LiPo batteries can extremely dangerous if not handled correctly, causing fire and even explosions. In this guide I will…
