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.

Check out a detailed review on our new /Learn page!
