Drone Flying 101 – An interactive tutorial for beginners

Original Article ↗ Hacker News Discussion ↗

Simulator-based FPV training

  • Strong consensus that simulators are essential for learning FPV/acrobatic flying: drastically cheaper than crashing real drones and skills transfer well.
  • Popular sims mentioned: Velocidrone, Liftoff, DRL, Freerider FPV, FPVSIM. Velocidrone seen as most “pro” and physics-accurate; Liftoff praised for features and PID tuning practice.
  • Time-to-competence estimates vary: some say 20–100 hours to be truly comfortable; others argue 30 minutes–2 hours is enough for basic flying.
  • FPVSIM’s web version runs on most platforms but users note annoyances (repeated controller calibration, Firefox stutters, limited control mapping, designed mainly for on-screen joystick).
  • Sims also used to learn PID tuning and, to a lesser extent, to test whether motion sickness is an issue.

Controllers / Radios

  • Broad recommendation: radios running OpenTX/EdgeTX with ELRS protocol; they work as USB/BLE gamepads for sims and real drones.
  • Common picks: Radiomaster Pocket, Zorro, Boxer, TX16S; some like “gamepad” form factor, others full-size.
  • DJI and BetaFPV radios are viewed as more limiting: ecosystem lock-in, compatibility mess, latency, and quality concerns.
  • Debate ELRS vs Crossfire: ELRS considered technically ahead, cheaper, and fast-evolving; Crossfire praised for ease of updating/pairing but seen as stagnating.
  • Emphasis that FPV needs a non-sprung throttle axis and high input resolution; regular gamepads are seen as inferior.

FPV vs GPS/Cinematic and Hardware Choices

  • Two “families”: GPS-stabilized cinematic drones (e.g., Mavic-type) vs FPV/acro quads.
  • Cinematic GPS drones are easy to fly; FPV is harder but more engaging and used increasingly for dynamic “cinewhoop” and action shots.
  • DJI dominates non-FPV and FPV video links, though many FPV pilots build custom quads (GepRC, iFlight, Nazgul, cinelifters, whoops).

Regulation and Licensing

  • Disagreement over how restrictive EU rules are. Several commenters say sub-250 g drones are widely flyable without per-flight permits, subject to standard limits (no crowds, airports, some nature reserves).
  • FPV in EU typically requires a visual line-of-sight spotter; some find this impractical but note it’s rarely enforced in low-risk areas.
  • Mention of simple, free online EU pilot training and registration; local quirks (e.g., beaches, city bans) vary.

Military and Ethical Aspects

  • Lengthy discussion of FPV drones in Ukraine: from tank-killers to targeting individual soldiers, plus recon and artillery spotting.
  • Disagreement whether FPV drones are “novelty” vs central to modern warfare; many argue they’ve reshaped tactics, especially when combined with ISR drones and jamming.
  • Emerging trend toward machine-vision and autonomous or semi-autonomous strike drones; concerns about escalation and psychological impact on operators.
