Elekton Controls is located in Bayport. It is the central location for the third book of the Hardy Boys series. It was built on the site of an old windmill, which was incorporated into the new design. It is used to design controls for space missles. It is bombed as part of a sabatoge groups plans. Fenton Hardy was responsible for disarming one of the two bombs that were set, as he wasn't able to get to the second in time to disarm it.
