FPV Racing Drone

Overview

The FPV racing drone is a 5-inch carbon-frame quadcopter flown first-person through video goggles. The pilot sees a live feed from a nose camera while steering with an ELRS radio, giving the immersion that defines freestyle and racing flight. The package spans the aircraft, the FPV Goggles, and the Radio Transmitter.

The airframe is the Carbon Frame: stacked carbon top and bottom plates separated by aluminium standoffs, four 5 mm arms each carrying one motor, and a camera mount flanked by 3D-printed TPU bumpers and antenna mounts. Four Brushless Motor outrunners spin 5-inch tri-blade Propeller units.

How it works

Thrust is managed by the Flight Controller and the 4-in-1 ESC. The flight controller carries an MCU, an IMU, and a barometer; it reads stick commands from the Radio Receiver and the IMU, then commands motor speeds. The 4-in-1 ESC drives all four motors from one board, with a low-ESR bus capacitor smoothing current ripple and an XT60 feeding power from the LiPo Battery, a 6S high-discharge LiPo pack.

The pilot's view comes from the FPV System. A low-latency FPV Camera feeds a 5.8 GHz video transmitter that broadcasts through a circular-polarized antenna; the on-screen-display chip on the flight controller overlays battery voltage, timer, and warnings. The goggles receive that feed on dual micro-OLED displays.

Control travels over a separate ELRS 2.4 GHz link from the radio to the receiver. A Buzzer & LED Strip module adds a lost-model alarm and indicator LEDs, and an optional GPS Module adds GNSS positioning for rescue and return-to-home. Onboard wiring is gathered into the main Wire Bundle harness, keeping the stack tidy inside the frame.
