The Joystick Enhanced Device Input (J.E.D.I.) Control System allows you to control all the features of your full-scale droid with a single 6 channel R/C receiver.  For those on a budget, the Vex 6-channel radio, that can be found on E-Bay for around $30, and is a fine way to control your droid in radio quiet settings.  However, through use of a Receiver Converter, other R/C radios may be used as well (and provides more frequencies, or more reliable operation if using 2.4GHz radio). The J.E.D.I. Control System reduces the total electronics cost of a fully functional R/C droid by integrating and coordinating the many functions of a full-featured droid.  The main component is the J.E.D.I. Controller board that coordinates all features using input from the droid wrangler via J.E.D.I. joystick strokes.  Additional components bring logic displays, dome lights, sound, and servos together for a fully integrated solution.  Explore the links at left for more information.
