AeroVelo, a team of students and graduates of the University of Toronto, began flight testing its Atlas quad rotor HPH on 28 August 2012.

[1] The core team of AeroVelo is the same group that created Snowbird, the first successful human-powered ornithopter.

[2] The Atlas is the largest HPH ever flown,[3] and has a tip-to-tip rotor span of 154 ft (47 m), second only to the Russian Mil V-12.

[4][5][6][7] The peak power of 1.1 kW (1.5 hp) was generated only during the first few seconds to climb to the required 3-metre (9.8 ft) altitude.

[7] Control was created by leaning the bike, which flexed the entire helicopter frame, tilting the rotor axes.
