propeller options

Ground Effect

  • When quad is close to surface → prop wash bounces air → airflow becomes turbulent
  • Creates unstable lift → drift or wobble sideways

PID Sensitivity

  • Too high P/D gains → overreact in turbulence
  • Too low I gain → can't hold position → drift

Throttle Resolution

  • Small throttle change indoors = big lift difference
  • Harder to keep steady near ground

prop wash

📌 What is Prop Wash?

  • Prop wash is the turbulent/dirty air created by a drone’s propellers.
  • When the drone flies into this disturbed airflow, the flight controller struggles to stabilize, causing:
    • Wobbles
    • Vibrations
    • Shaky footage

🔍 Typical Signs

  • Shaking after a quick throttle drop → sudden throttle punch.
  • Jitter when coming out of sharp turns.
  • Visible oscillations in blackbox logs.

Propeller Blade Count vs Flight Stability in FPV Drones

1. Two-Blade (2-blade)

  • Pros: Very efficient, longer flight time, strong thrust
  • Cons: More vibration, noisier, less stable control
  • Best for: Outdoor speed, racing, long endurance

2. Three-Blade (3-blade)

  • Pros: Good balance of thrust and efficiency, faster response, more stable than 2-blade
  • Cons: Slightly less efficient, shorter flight time than 2-blade
  • Best for: Freestyle, cinewhoop, general indoor/outdoor flying

3. Four-Blade (4-blade) / Five-Blade (5-blade)

  • Pros: Very stable, smoother at low speed, softer noise, excellent control
  • Cons: Less efficient, drains battery faster, noticeably shorter flight time
  • Best for: Indoor FPV (Tiny Whoops), precise control, stable video shooting

Indoor Recommendation

  • Best choice: 3-blade or 4-blade props
  • Why:
    • Indoor space is small → low speed stability and smooth control are more important
    • 4-blade or 5-blade props give “stickier” control indoors, easier to hover and move slowly
    • 3-blade is a good compromise between stability and efficiency

👉 Summary:

  • Indoor practice / fun: Use 4-blade (better stability & control)
  • Mixed indoor/outdoor: Use 3-blade (balanced performance)
