I fly my FPV when I just want to fly for fun, which is about 90% of the time. Nothing compares.
While I've developed good manual skills, I probably fly 50% of my FPV time in Sport mode using the Motion Controller, which simulates a traditional aircraft control stick in your hand.
The flight controller then flies the drone very much like a fixed-wing plane, continously controlling camera pitch to simulate pitch behavior of a plane.
The result is a thrilling, heart-pounding experience that feels like racing around in a high performance jet. This can not be duplicated with the standard RC – impossible to duplicate the camera pitch control.
Here's a clip from a few days ago... working my way to shooting the pier at full throttle. This one was around 40mph on exit!!
