A servo control system was a part used in podracers.
Anakin Skywalker needed a servo control system to fix his podracer before the Boonta Eve Classic. Qui-Gon Jinn was able to obtain one by either trading a fuel converter and a repulse booster to Barbo or an engine binder and a repulse booster to Teemto.
Qui-Gon could also obtain the servo control system by killing Barbo or Teemto and stealing it from them, but Anakin would then refuse to accept it.
