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.
There are up to 72 FPV channels in the 5.8GHz analogue system. This article contains tables and charts to enable you to look up the specific frequency for each channel and band to ensure the best possible video signal from your rig.
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 often hear “higher gain antenna has longer range”, but don’t be fooled! Antennas doesn’t amplify radio signals, but rather just changes the radiation pattern, which is a trade-off between coverage and range. Antenna gain is a reflection of the maximum range you can get.
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.
LC filter is one of the most basic filters in electroincs, which comprises of just one inductor and one capacitor in its simplest form. This circuit is widely used by FPV hobbyists to suppress noise in power created by ESC and motors. Read More
When it comes to radio receiver (RX) and transmitter (TX) protocols, confusing acronyms are often used: PWM, PPM, SBUS, DSMX etc. In this post we will explain the differences of these RC TX and RX signal types.
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.
