Guess I didn't think that one through, did I Frank? There are several gizmos on the market to do this. Here are a couple:

The servo signal is not an analog signal, it is a logic signal with a 1-2ms wide pulse that repeats approx every 20ms. As such, it can't be used directly to trigger anything, it must be interpreted by another circuit. The receiver pin also doesn't source enough current to drive anything other than logic levels. Simple PIC circuits can be designed to translate from servo signals to switches of any size. See: http://www.anvilus.com/mrc.html for an inexpensive circuit that can drive 4 relays (or any 150ma load) from two servo channels. It even includes mixing if you want that feature. Add 4 inexpensive auto relays to that circuit and you'll have a solution that is far less expensive and far easier to fix than anything else on the market.
