FPV Drone Snippets

Betaflight configuration, tuning, motor and prop theory, power, radio link, video, and hardware setup for FPV drone builds — grouped into the categories below.

Categories

  • Aerodynamics
    Propwash, rotor downwash, and ducted-fan airflow — the physics behind how a multirotor flies.
  • Motors & ESCs
    Motor KV, prop matching, timing advance, ESC PWM frequency, and DSHOT/RPM-filter theory.
  • PID, Rates & Tuning
    PID theory, the Betaflight tuning math, rate curves and modes, blackbox-driven tuning protocols, and cinematic tunes.
  • Power & Batteries
    LiPo cell chemistry, C-rating and cell count, storage and care, plus capacitor selection and placement.
  • Radio Link & Antennas
    ExpressLRS configuration, RSSI/LQ/SNR telemetry, and antenna placement for RC and video links.
  • Reference
    FPV terminology glossary and a Betaflight vs INAV firmware comparison.
  • Setup & Safety
    Flight modes, failsafe and GPS Rescue, stick commands, CLI backup/restore, preflight checks, and common build pitfalls.
  • Video & OSD
    Analog vs digital FPV video systems, OSD element setup, and mapping VTX power to a transmitter switch.
