After building our first Arduino-based flying drone robot, we decided to take what we learned and build a tiny quadrotor that was safe to fly indoors and out. We used the same electronics, but built the frame out of ABS sheet and kite parts. This little robot, which we call the Black Hornet, is about 7″ across between the props.  He’s great fun to fly day or night (he’s equipped with two arrays of cool blue LEDs), and definitely sounds like a huge hornet.

The Mini Flying Drone has since been upgraded with an all new frame design based on a sandwich of three custom-made carbon fiber plates and four carbon fiber square shafts.
