Here a regular gaming pad, perfectly capable to control your aircraft when in manual or assisted flight
Here and example of an Joystick that looks like an RC transmitter, but is just an USB connected Joystick. Handy for quick tests, and for ER 13, why not add one to you Paparazzi toolset?
Here a real RC transmitter connected via trainer port to your PC to be used as a Joystick
Also supported are USB based Nintendo gamepad controllers useful when flying in NAV/GUIDED modes
If plugged in, under Linux a quick test to see if the device is recognized via:
Although the message is a little different for every joystick type, it should display something like this in last lines:

You should always calibrate your joystick. By calibrating you make sure that your Joystick is not sending steering commanding values; while it should not when the steering sticks are in neutral position.
Install the joystick and the jstest-gtk packages via:
$ sudo apt-get install joystick jstest-gtk
Use the graphical jstest-gtk tool (or the commandline jstest) to view/edit your joystick calibration and axis/button mappings. Start it via:
Store the calibration
Your calibration and mapping will only be lost once you unplug the joystick, so store your configuration via:
$ sudo jscal-store /dev/input/js0
If you replug your joystick the next time, udev should take care of automatically loading the appropriate configuration.
Whether you are running on Mac OS X or Linux, the test_stick tool provides the ability to profile a joystick device.
$ ./sw/ground_segment/joystick/test_stick -h Usage: ./test_stick <option> [<option>...] Options: -d <string> device name -h display this help
The default device name is set to 0 if the -d option is not specified.
Here's a snippet of the tool output when a single USB enabled SNES gamepad is connected.

TIP: To display this RC transmitter in a simulation session remove the default ""--norc"" option from the session commandline You can give realtime steering input and switch modes while the aircraft flies it flightplan via the simulated flight.
