You can always learn a thing or two about technology by studying what others are building. The Ball Drone is worth a look for those of you into DIY drones. It is a self-made ball-drone with air vanes for position control.
This 3D printed drone has 4 air vanes and only one rotor. It also has a brushless DC motor. The project requires a turnigy digital servo TG9d, TMS320F280049PM controller, and a BR2830 BLDC Motor.
