First-Person-View (FPV) is a different flying technique that defers from typical line-of-sight flying which involves the pilot to maintain visual sight of the aircraft as he/she controls it’s direction. Facing away from the pilot the controls on the radio (remote-control) turning right to turn right and turning left to turn left. If however the direction of the aircraft changes to face the pilot then controls are now opposite. Rolling left on the radio will turn the aircraft to the right and vice versa.
It’s the easiest way to become a fighter pilot without quitting your day job!
When flying with first-person-view (fpv) there is a small standard definition camera mounted on the aircraft and the pilot uses either goggles or a screen to “see” as if the pilot was sitting in the cockpit of the aircraft. In this case, direction will always remain the same. In this flying mode the pilot can perform complex manoeuvres and still maintain full control and orientation of the aircraft.
The experience of flying something you built is amazing, and being able to fly something like a fighter jet, making barrel rolls and dog-fighting manoeuvres is something. Where else could you have this ability unless you are a trained and active Air Force pilot!
