In this guide I will show you where to get the uninverted SBUS and Smart Port signals on many different Frsky receivers, including the R-XSR, XSR, X4R-SB and XM.
Lipo battery balance plug can sometimes be damaged by spinning propellers in flight. it’s extremely unsafe to use this LiPo with a broken balance lead as it can short itself easily and cause fire. In this article I will show you how I fixed mine.
The new GoPro Hero 2018 edition is cheaper than the Hero 5 Black, but it won’t do 4K nor 2.7K, only up to 1440p. There are some other features missing too. Interestingly there are smart people out there managed to turn it into a Hero 5 Black that is capable of recording 4K videos!

Before throwing away damaged or old LiPo batteries, you should first drain them completely until there is no charge left. In this article I will show you how to build a battery discharger using high power resistors.
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
The Frsky X-Lite has an external module bay that is too small to fit standard size JR modules including the TBS Crossfire. Are we giving up that easily? HELL NO! A few people have been taking the X-Lite apart as soon as they received the the first batch, and trying to find out whether they can get it working.
