RC helicopters have become so cheap that they’re now a really attractive robotics platform. This guide gives a jumping off point for starting your own project. It covers how to integrate a Gumstix embedded linux system into the helicopter. Code is provided so that you can hook up a usb controller to your laptop and control the helicopter over Bluetooth. All you need to do after that is build some cool controls, hook up a speaker and start streaming Ride of the Valkyries.
