Kitty Hawk, funded by Page, unveiled a "Flyer" model it described as "an exciting first step to sharing the freedom of flight."
The company was created last year in Google's home town of Mountain View, California, and has been testing a prototype in New Zealand.
Images and details were available at a freshly launched website at flyer.aero, and CNN posted coverage of a reporter taking to the air in a Flyer over a lake at a test site near Las Vegas.
The electric aircraft had 10 small lift rotors on its wings, making it capable of vertical take-off and landing like a helicopter.
Kitty Hawk said that at 15 meters (50 feet) away, it sounded about as lound as a lawn mower, while from 250 feet away the volume was on par with a loud conversation.
Test flights by first-timers were over water, with the top speed limited to 32 kilometers per hour (20 mph) and the altitude to no more than three meters.
The uncovered cockpit appeared big enough for one person, with their head poking out as it might from a go-kart.
