When talking about radio receiver (RX) and transmitter (TX) protocols, you will surely encounter some confusing acronyms like PWM, CRSF, SBUS, DSMX, FPort etc. In this guide, I will explain all the common RC protocols…

FPort is a new Frsky receiver protocol which brings a few improvements over the existing SBUS and SmartPort Telemetry. This tutorial will explain the advantages of FPort, and how to set it up on Betaflight…

The Mini Immortal T Antenna is now available for TBS Crossfire receivers. These antennas are super tiny and should be great for micro quads such as Tiny whoops and “Toothpicks”. Let’s compare its performance to…

There are many transmitter options available for mini quads. While many would recommend a high end transmitter, beginners might choose to save a bit of cash on selecting a TX. This is completely understandable when…

This tutorial will show you how to make your own DIY SBUS to USB converter. This would allow you to fly FPV simulators wirelessly using any FrSky SBUS Receiver. All you need is a cheap…

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.

The Dock-King from FuriousFPV is a ground station that houses the True-D diversity module. It uses better algorithm to improve video signal from the True-D receiver module.

In this post we will share some findings and results regarding the latency of FPort receiver protocol. Separate tests were run on the XSR and R-XSR RX’s, using a logic analyser.

So you want to flash Frsky RX firmware, but too lazy to take your quad apart? You can flash it through your flight controller, just like how you flash your BLHeli ESC’s using FC pass-through.

It’s important to setup failsafe properly on your mini quad for maximum safety and preventing fly-away. In this tutorial I will explain what failsafe is, and how to set it up in Betaflight as well…

  There are a whole range of radio receivers (RX) for the Frsky Taranis, and I have rounded up the ones suitable for mini quads and micro quads in this article. We will explain the…

The FrSky’s R9 receiver is designed to work with the Frsky R9M long range module, however it was just a bit too big for mini quads. Therefore Frsky made a smaller version, the R9 Slim,…
