Improved circuit design
Newly upgraded Temperature Compensated Crystal Oscillator (lower packet loss, high frequency stability)
High-performance at 2400MHz or 900MHz (900 / 868 bands available)
Make sure to install the antenna away from conductive or magnetic components (carbon, metal, motors).
Flash the latest firmware and follow the ELRS Community for updates, tutorials or contributions.
Use iFlight ELRS receivers coupled with our transmitter for maximum performance! We’ve probably achieved market’s best crystal frequency stability at a very low frequency deviation. Please checkout this article for further information https://github.com/ExpressLRS/ExpressLRS/wiki/Crystal-Oscillator-(XO)-Frequency-Error
The 900MHz as well as 2400MHz band have outstanding performance and long range capabilities. If you’re not sure what to get, please checkout the official ELRS Long Range Competition to see what has been achieved. https://www.expresslrs.org/2.0/info/long-range/
What can you expect? Due to local regulations, the 900MHz FCC region seems to have a better performance than the 868MHz EU region. The 2400MHz band works great in any region, has a higher packet rate up to 500hz. This is not a common 2400MHz protocol and cannot be compared to anything prior on the market.

What is a Video Transmitter?

VTX stands for video transmitter, this is the heart of the FPV life system. Pumping life into the many possibilities of FPV. VTXs come in many different shapes, sizes, strengths, and wiring setups. Strapped to the front of the quad is an FPV camera, and strapped to the head is a pair of FPV goggles. You can watch live, instantaneous footage right from the cockpit because the VTX is sending the footage received from the camera out to the goggles.
You are picking the right VTX for you. This will start with knowing if size and weight are factors for you. If you are planning to race, and only race, then you will select any VTX that is light in weight. It’s probably important that your VTX can do pit mode and channel control (depending on which one you choose). This may be a smart audio feature or the tramp protocol. Pit mode is where you will be able to set your VTX to a certain mode that allows you to power up your quad without powering up your VTX to keep you from blasting video and trampling over other racers on the track. Channel control allows you to change your frequency right from your radio for easy switching at a race, or to prepare your quads for the race the next day. Seeing that range is not so much of a factor in a race, only 25mw is allowed, and all that you need. So you can pretty much pick any when it comes to figuring out which is best for you and your power output needs.
