This is the most innovative, feature-rich flight controller anywhere on the market. With a speedy F4 processor, full graphics capable OSD, and stackable form factor, it has all the basic essentials - but it's the details that count.


The Radix immediately makes an impression with its unique integration of the Betaflght OSD, which is fully graphical - add your own pilot or team logo to the OSD, or download one of many popular brand logos to show off your components. The BrainFPV Logo Customizer makes it easy to put your own stamp on the OSD.

That's just the start of the features this board provides: a built-in barometer displays altitude data right on the OSD, the MicroSD slot gives you black-box logging, there's even a dedicated camera pad that gives you the ability to adjust your camera settings on the fly.

The 180MHz F4 processor not only gives you quick response times, but also makes sure there's plenty of processing power to spare to handle all your peripherals - the board has four UARTs. When setting up the board you'll be amazed at how well laid out the solder pads are in relation to their relative components, and wonder why other FCs aren't like that.

Whether you're racing, flying freestyle, or going long range, the Radix is your next FC.
