Some quadrotors can be dangerous if flown carelessly. Depending on the size, weight, and power of the quadrotor, collisions with property, people, or pets can cause serious damage. At the very least, crashes of your quadrotor can damage the craft and end your flying career until you purchase a new one or repair the damaged one.
Although this book is not about flying quadrotors, we believe that some discussion of good flying practice is necessary. The discussion will be particularly helpful to new pilots.
