At just nine feet long, the Dryosaurus' relatively petitesize could make it attractive to a private collector interested in displaying a Jurassic specimen in his living room.
The petitesize naturally means a smaller internal battery (rated for 4.5 hours, compared to the original's six), but JayBird let us know that the Sprint is acoustically identical to the JF3.
The first, called Ease, is a mere foot in diameter by 16-inches tall and can fly safely in tight spaces or through open windows or doors, thanks to its petitesize and ducted rotors.
