It's a DJI Phantom. They are a consumer-ready quadrotor - almost anyone can fly one.

I looked a tech spec, could not find a flight duration. Have you any idea of flight aloft duration?

This information is incredibly hard to get from most multirotor makers, because it's always really bad and they don't like to be compared to each other.

From the battery size & numbers for this general class of quad I'd guess 15-20 minutes (confidence +/- 5 minutes), although that depends whether you put a camera on or not, and if so what.

Our DJI S800 airframes will go to 30 minutes with a full load of batteries, but they are much larger and more efficient.

It says at the bottom of the "Features" (http://www.dji-innovations.com/feature/phantom-features/) page 10-15 minutes of flight time.

I bet contacting the owner via Twitter (@Jenk1907) would help. Or the email address shown in the video (jenk1907@me.com).
