Saw this DIY quadcopter at the Drone 101 course I attended earlier today:
According the the guy who “built” it, the original frame broke. It would have been a waste to throw away the drone since everything else was in good condition. So they decided to experiment using cardboard as the frame.
And yes, it is able to fly…
