🛩️ FPV Basics

Everything you need to know to understand First Person View drones

What is FPV?

FPV (First Person View) is a method of piloting a drone where the operator sees exactly what the drone's onboard camera sees in real-time, through specialized video goggles. This creates an incredibly immersive experience—you feel like you're sitting in the cockpit of a tiny aircraft.

FPV vs Camera Drones: Unlike DJI Mavic-style drones which are GPS-stabilized and flown via smartphone screens, FPV drones are fully manual. The pilot has complete control, enabling speeds over 200 km/h and acrobatic maneuvers like flips and rolls.

How FPV Works

Video Signal Chain

Camera → VTX (Video Transmitter) → RF Signal → VRX (in Goggles) → Display

Control Signal Chain

Radio Transmitter → RF Signal → Receiver → Flight Controller → ESCs → Motors
