▾ What are the effects of pitch and diameter?

Propeller pitch
Pitch
  • Higher pitch propellers will go faster at top end speeds.
  • Lower pitch propellers will have better acceleration, fuel efficiency, and pulling power.
Diameter
  • Smaller diameters achieve higher top end speeds.
  • Larger diameter propellers are great for pushing heavy loads, maneuvering at low speeds, and getting excellent hole-shot.
