High Power Launch Controller

Here are some PDF file of my two pad 12 volt high power rocket launch control system. This system was built with several parts from my electronic parts box. The control box case was purchased from Radio Shack. The system uses two 12 volt relays and a battery at the pad location and a remote via some left over cat 3 cable. I uses a wire reel to store the wire (600 feet) when it is not in use. You will need both files.
