The umbilical cables will double as security for your transmitters too..
Jamie's idea above for a simple mechanical timer switch could be incorporated in your switch panel if you so wished..
A simple push button timer switch like this may do..

The fail safe in the car and switch off the power to the tx is a great idea.
