Parkzone Extra 300 6S FPV Build

My very first RC airplane was the venerable HobbyZone Champ. It was a high-wing trainer which almost literally could fly itself. I loved it, my friend crashed it into my face, but I wished it could roll, flip, and do more exciting maneuvers a bit more gracefully. Next up was a Parkzone Ultramicro Mustang. It flipped well, it rolled well, it was much faster than the Champ, and I loved it. But the dihedral in the wing made it tough to fly inverted, and the size meant it struggled to carry even just a stripped down pen cam.

And then I got drunk one night and went on Amazon.

A day later, a Parkzone Extra 300 was at my door. It was fast, had legitimate aerobatic creds, and could comfortably carry a GoPro. I flew this plane line-of-sight for years. After catching the FPV bug, I knew I had to FPV a plane like the Extra. So, that's what I did, and this is how I did it.
