Reading Values from PPM RC Receiver

I am trying to get a range of values from a Futaba RC receiver in PPM mode thru the Serial Monitor on a Arduino Uno. I got the design from Make Magazine for building a RC lawnmower. I've tried reading it as both an Analog and Digital signal, with no success. All the hardware checks out as far as connections and such. I'm getting a number right around 260, whether or not the RC receiver is plugged in. I'm wondering if anyone else has tried this or if someone has some advice for me. I can provide more detail (i.e., the program) if needed as far as troubleshooting I've completed.

It isn't an analogue signal, so reading it as such is not a good idea.
Have a look at using "pulseIn"
