With the Joystick4UAV app you can control your multicopter with a joystick. The app is based on the Joystick2PPM app and has been extended specially for the use with a multicopter by supporting six flight modes. Please refer to the picture below for the system setup and to the app web page for more information.
PLEASE NOTE THAT THIS APP CURRENTLY ONLY SUPPORTS A LOGITECH EXTREME 3D PRO JOYSTICK AND A USB2PPM PIKODER.
