Pirx 5 Freestyle - because analog dead-cat is just better!

Pirx 5 Freestyle FPV frame

Everything in the 5" freestyle FPV frames was already discovered and we do not need new frames? Bullshit! All the frames that I tried so fast, even the ones from the most reputable manufacturers, were always "ok, cool, but I do not get this think over here!". Pick your own: too tight, not a good place for a GoPro, lack of mounting options, and dozens of other WTF moments.
