BrainFPV brings us their latest creation, the Radix Flight Controller. With a speedy F4 processor, full graphics capable OSD, and stackable form factor, this FC has all the essentials but with many things, it's the details that count. There are so many, you'd be better off looking at the specs yourself.
Full-graphics capable OSD with horizon, gyro spectrograph, RC stick display and more.
Flexible design means easy builds with a stackable form factor with Radix PDB or Hobbywing 4-in-1 ESC
