How to setup Custom Logos in OSD



Introducing radix, the smartest, most innovative line of drone electronics BrainFPV has ever developed.


On top of the normal Betaflight OSD, radix on-screen-display gives you extra features you can't get anywhere else. Extra features also include a graphical barometer scale, artificial horizon, gyro spectograph, RC stick display, 3D OSD support and more! 


There are WAY MORE features than customizing your logo on the splash screen. Features you cannot get with the normal Betaflight OSD. You have heard about the graphical features of our OSD. But what exactly are they, and how do I use them? Find out about all the cool features and how to enable them here: HOW TO PIMP YOUR BRAINFPV OSD


Radix is engineered to perfection with a visually stunning form factor and plug-and-play stacking. The radix flight controller uses soft cables for vibration isolation and stacks seamlessly on the radix power board, Hobbywing 4-in-1 ESC, and radix wing power board (wPB). Its simple, sophisticated design facilitates a faster build time and minimizes human error.

  • The fastest STM32 F4 processor running at 180MHz, as well as the industry leading Bosch gyro for an unparalleled flight performance!
  • Integrated BAROMETER, a necessity for long range flyers! How high are you?
  • Never run out of space with the MicroSD card slot for logging enthusiasts!
  • A dedicated camera control pad for changing camera settings in the field!
  • FOUR full hardware serial ports (UARTs), making it easy to use telemetry, change VTX settings, without ever running out of ports! Two of them feature signal inverters for S.Bus and SmartPort, allowing for a flawless setup!
