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

10. 1. 2020 | The Verge | www.theverge.com

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

Add to this the reduced battery drain from running fewer propellors and the drone’s compact form when the two arms are folded, and you have a pretty convincing sales pitch. In addition to its bicopter design, the Falcon looks kitted out for aerial photography and videos. There’s a 12-megapixel main camera mounted on a three-axis gimbal, with a 1/2.3 inch Sony CMOS and Qualcomm ISP capable of capturing 4K video at 30fps.
