Building Multicopter Video Drones

Book Description

Build and fly multicopter drones to gather breathtaking video footage

In Detail

Multicopters have revolutionized the television and film industry. For the cost of just a few hours of traditional helicopter rental, videographers and cinematographers can own a multicopter drone that shoots stunning aerial shots that helicopter pilots can only dream of. This book is a practical guide that aims to help you learn how to build, fly, and program your own drone.

The book starts by explaining the physics of multicopter flight and then walks you through all of the decision processes when choosing a platform. From turnkey systems to custom-built multicopters, you will not only comprehend the working of the components, but also gauge why the choices you make are crucial and how they affect your flight. As you go through the book, you will gain a firm grip on the principles, choices, and safety issues involved in a multicopter flight.

Finally, it will teach you the maneuvers to capture great camera movements and explain the intricacies of stabilizing them in post-production. In short, you will be well on your way to becoming a professional multicopter videographer.
