By default you can only get the total battery voltage with Crossfire telemetry. Here’s an easy trick to get averaged cell voltage from telemetry, so you don’t have to do the math in your head.

New Feature in OpenTX 2.3.10: RXNUM – Receiver Number for Crossfire
In the latest OpenTX they added “model match” to Crossfire, i.e. RXNUM which is basically a number you can assign to a model before binding the receiver, this allows the model profile on your radio can only control a particular receiver.
LQ and RSSI in TBS Crossfire
LQ and RSSI can be confusing for first time TBS Crossfire users. I will try to explain the differences between LQ and RSSI for Crossfire. I will also show you how to set it up in Betaflight and OpenTX to monitor your link quality and range.
How to Fly FPV in the Winter!
Flying FPV in the winter can be hard on RC pilots and models. Low temperatures can even lead to such profanity as “nice weather for flying, but it’s too cold to go out there!” Here are a few tips that can help you and your drones survive those winter FPV sessions.
The Guide to FPV Flying | First Person View System
In this article we provide advice on how to choose the hardware needed for an FPV setup, some useful tips about flying FPV and explain the different common configurations of FPV systems used in FPV drones.
DJI FPV Signal Strength Explained – Look at Bandwidth, Not the Bars!
The signal bar in DJI’s FPV Goggles is sometimes unreliable, I found bitrate (aka bandwidth) is a much better signal strength indicator. If you use Crossfire, you can also display LQ in OSD although it’s not yet supported.
How To Replace Camera and Cable in DJI Air Unit and Caddx Vista
Here’s how I normally replace the camera or coaxial cable that connects the camera and Air Unit or Caddx Vista. These parts are user replaceable by design, so it’s very easy to do.
How to Get Started with FPV Drone
So you are new to FPV Drone and wondering where to start? You have come to the right place! This beginner’s guide explains the basics of buying, building and flying an FPV drone.
How to Improve Radio Control Latency for FPV Drones
Minimizing the radio control latency can improve flight performance of the FPV drone, as well as giving the pilot more confidence and faster response. In this post I will explain how to reduce RC link latency as well as the considerations.
How to Setup GPS Rescue Mode in Betaflight
GPS Rescue mode in Betaflight is similar to “Return to Home” on a DJI drone. It is meant to help bail you out when your video feed or radio signal gets sketchy, the quad is supposed to return to you automatically using GPS.
DJI FPV System FAQ – Common Issues, Questions and Tips
Here are some of the most commonly asked questions about DJI FPV Goggles, Air Unit, Caddx Vista and Remote Controller. I will keep adding to this list as a knowledge base so we can all find the answers easily.
Why Use Linear Polarized Antenna on Radio Transmitter (And Not Circular Polarized)
Circular polarized antennas (CP) are far more popular for FPV setups, but why most radio transmitters still use linear polarized antennas (LP)? In this post we will explore the differences and explain the advantages of CP and LP antennas for radio transmitters.
