Salvaging RC Vehicle Parts

Its getting close to the wire now so to say. My robot project operates without any real set dates for when I do things or release updates. However, it is my goal to have Salvius fully mobile before August 30, 2012. Today I stole salvaged the RF receiver out of an old RC vehicle in order to satisfy my need for a quick way to control the robot's arms. Ideally I would like to have more controllers that I can use with the Arduino but I don't have the money at the moment, nor do I have controllers picked out if I did have it.
