Put a small screw tip on a drill, cause there are a lot of screws to get off! It's easy to get to the pots as Sokel linked in that thread, however if you want to actually remove the pedals it requires the full teardown of the stock units. Once you have the bottom off a ton of little parts want to fall out (little pins and tiny wheels), cause these things are a mess of little parts inside. Basically the pedals are attached to wheeled sleds via 4 screws, and once you get access to those you can remove the pedals but they can only be accessed from underneath the sleds which are only accessible by opening the entire assembly. If you are using them for a mod then it's pretty easy to get them out, but if you wanted to rebuild the
Saitek pedals as they were before you opened them, have fun with that! :p
