Quadcopters and drones

This is currently a skeleton page. Please help by adding your contributions either here or in the associated Discussion page.

This page will cover flying toys as well as larger and more serious drones.

Summary

In recent years the availability of lithium batteries with a high power to weight ratio and of cheap control electronics and sensors has made possible both flying toys or various sorts and drones for professional and serious amateur use. Particularly with toys, damaging crashes are common, but other faults may also arise.

Safety

Be sure you know how to fly your device safely. Rotating propeller blades can be dangerous.
