Drone Speed Calculator

Estimate your drone's theoretical and realistic top speed

Revolutions per minute of the motor
Propeller pitch in inches (e.g., 4.3)
Propeller diameter in inches (e.g., 5)
Optional — for estimated RPM check
Optional — KV rating of your motor

Estimated Speed:

Enter values and click 'Calculate'.

Note: Theoretical speed assumes zero prop slip. Realistic speed accounts for ~25% loss from drag, prop slip, and air resistance.
