Designing a parachute system/device

  1. Oct 9, 2008 #1
    I am trying to build a system to activate a servo at a unspecified point in time when a machine and remote looses their signal between another. When the signal is lost between the two, the new system must activate a servo. We are using radio transmitters, but I can't figure out how to tackle this problem. Any assistance would be LOVED!!!

    The biggest problem I am having is how to link these three things together. I was thinking about using a sensor that monitors the 2-way signal between machine and remote with a LED, then the LED turns on or maybe stops the LED when the signal is lost, then activates the actuator... i don't know...

    can i build a sensor that does this?

    Should I buy transmiter and put it on the plane and connect the reciever to a circuit that activates the servo? Im trying to make this happen without me doing it manually. Does this make any sense?
