I only have some cheap FPV gear, but if I were to go all the way, I would get the Skyzone 3D FPV googles and camera, or maybe just a craft big enough to carry an old GoPro Hero 2 3D rig.
Sure it seems like a gimmick, but 3D FPV seems like a natural pairing. Until I win the lottery and can afford a Skyzone setup or even a rig large enough to carry an insane 3D GoPro rig, I’ll just have to live vicariously through others.
