When highly evolved nano-aliens descend upon our planet to mine our plethora of carbon monoxide gasses they’ll surely be piloting something like this Mini HoverDrone. This is by far the smallest flying R/C device we’ve ever seen and it’s damn impressive in the air. With a diameter not much larger than a silver dollar and a single propeller on the bottom, the HoverDrone somehow manages to float in the air as it spins and flashes its blue LED. The simple slider control allows only up-and down movement… but this makes it so easy to fly that anyone can instantly control it. Buy a few and create your own buzzing alien insect swarm.
