One thing to consider when using that sort of slides for the mechanism as in the link posted by 531 Ghost is that they are not made to support large loads at the extreme of deflection in that direction. I know because I have used them the same way in my own design (here are some pics: http://s5.photobucket.com/albums/y172/Brandano/DIY%20Rudder%20Pedals/ ), and had to modify them slightly later to avoid some binding with the screw heads. It would be better to have the rails on the sides of the pedals rather than underneath them, or to have some sort of wheel supporting the weight, with only one sliding bearing to keep the pedal aligned. Also, using two parallel linear bearings mean they must be very precisely aligned. If they are not perfectly parallel they will cause a lot of friction, and become loose over time as they deform.

This pedal in FlightSim is too ugly, and the use of pulleys is anti-KISS. Look at plans for Baloo Pedal: Build in parallelogram principle like most of commercial pedals: Simped, VKB, GS, discontinued TM RCS. Animated .GIF of VKB pedal. Look at Simped drawings, is very similar: http://www.dhs-electronic.de/img/produkte/6_f16c_voll.jpgThe spring system to center pedal is similar to one used in above pedals too. The only part in Baloo Pedal difficult do make is the foot rest, since original was built in metal by laser cut - JFA build one using manual methods, see in relative thread. Simply adjust this part to material, ie. Alluminium, MDF, Plywood, Plastic... and tools available. Similar project build with PVC tube and joints, bearings: http://www.sukhoi.ru/forum/showthread.php?t=38242I'm not saying that this project is the best available, but it is practical to build. For cheap USB controller, search for Logitech Attack 3 joystick, that have just 3 axis. Sokol1

My wiring diagrams won't be much use to you, because I am using the pedals port on my Thrustmaster HOTAS Cougar, that emulates an old PC Gameport for compatibility with older pedals. This is a picture of the wiring diagram I followed: http://users.skynet.be/fb011080/images/Hotas/prog_ch/pix1.jpgI replaced the rudder potentiometer with a homemade hall sensor later, which means that I had to tie the "free end" of the rudder potentiometer to ground like the two toebrake ones. This means that the potentiometer works as a voltage divider rather than a variable resistor. It's a bit of a subtle difference, but it essentially is an arrangement that is more stable, because it does not vary with temperature changes, and the Cougar seems happy with it. I think that even with the "variable resistor" arrangement the rudder axis potentiometer is just a portion of a resistor network.
