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 soldering skills.
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 where to install the caps in a racing drone.
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 fix “dead” motor outputs on an FC.
You can prolong the life of electronics in a quadcopter 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 experience. And it might actually help somebody in the future, who knows.
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.
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. Read More
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 we will show you how to dispose LiPo batteries safely.
Proshot is a new ESC protocol that encodes DShot using PWM pulses. In theory there might be some benefits in using Proshot over DShot. However whether or not it makes a noticeable difference and overweight the downsides, that’s another question.
I will show you how to flash Frsky receiver firmware on your R-XSR, R9 Mini, XSR, D4R-II, X4R-SB, XM+ and some other RX. Updating RX firmware is useful when you have the wrong firmware that prevents you from binding, and getting the improvements and bug fixes in the latest firmware.
In this FPV camera latency testing I will share my results on over 20 cameras, also my method of testing camera delay. FPV camera lag has impact on a pilot’s reaction time in flight, and it is one of the most important considerations in selecting FPV cameras.
Antennas for FPV can be categorized by their polarization: linear and circular. In this article we will discuss the differences between linear and circular polarized antennas.
