Overview of this book

The Ardupilot platform is an application ecosystem that encompasses various OS projects for drone programming, flight control, and advanced functionalities.The Ardupilot platform supports many Comms and APIs, such as DroneKit, ROS, and MAVLink. It unites OS drone projects to provide a common codebase. With the help of this book, you will have the satisfaction of building a drone from scratch and exploring its many recreational uses (aerial photography, playing, aerial surveillance, and so on). This book helps individuals and communities build powerful UAVs for both personal and commercial purposes. You will learn to unleash the Ardupilot technology for building, monitoring, and controlling your drones.This is a step-by-step guide covering practical examples and instructions for assembling a drone, building ground control unit using microcontrollers, QgroundControl, and MissionPlanner. You can further build robotic applications on your drone utilizing critical software libraries and tools from the ROS framework. With the help of DroneKit and MAVLink (for reliable communication), you can customize applications via cloud and mobile to interact with your UAV.

Chapter 7. The Holy Grail - A Fixed Wing Drone

Wow for a holy grail, she sure is one ugly pig, right? Well, prototypes just aren't usually pretty. So, why is a fixed wing drone (like the airplane in the following image) considered a holy grail?

The answer is pretty simple, actually. Airplanes need to keep moving in order to stay airborne. Go too slow, and you stall (a fancy word for fall from the sky until you build up speed again except that it's usually vertical speed, and vertical speed is going down).

With multicopters, tuning them is fairly easy: take it off, hover just outside of ground effect (OGE), and let it twitch around a bit. If it's too crazy, just land it, reset the settings, and repeat. Since an airplane is constantly moving tuning can be quite a bit more hazardous to the aircraft.

While tuning fixed wings, I've had them turn into lawn darts, porpoise like dolphins jumping out of the ocean, and (as stated in a previous chapter) blow their wings right off. So, it's important while...
