Fewer propellers mean more battery-life for the Falcon bicopter drone

When are two propellers better than four? When they give your drone extra battery life, greater portability, and reduce noise, claims Zero Zero Robotics. That’s the pitch for the company’s V-Coptr Falcon: a bicopter drone with an impressive flight time of 50 minutes — 20 minutes more than the comparable DJI Mavic 2.

For years, four propellers have been standard for consumer drones, offering greater power and stability. But Zero Zero says its tilt-rotor design, which lets each propeller swivel independently, allows the Falcon to match four-prop rivals. Tilting the propellers improves the drone’s aerodynamic profile, says the company, reducing drag.

Add to this the reduced battery drain from running fewer propellers and the drone’s...
