In this chapter, we have learned how a gliding drone flies, and a number of things about aerodynamics. I hope you will make a glider drone and share your experience with me. We also learned how you can make airfoil glider wings, add the components to the body of the glider, and how to set up ArduPilot. In Chapter 8, Building Prototype Drones – Racing Drone, we will make another type of drone known as a racing drone. The racing drone will be fun if you like competition with your friends. So, let's begin making the racing drone.
