OK, so I got it <almost> working now that I have this knowledge.  I plugged the RC Recevier into the Netduino 5V (I got tired of the 4.8V battery back needing to be rechanged) and I added this code:

        static OutputPort outputPort = new OutputPort(Pins.ONBOARD_LED, false);                public static void Main()        {            InterruptPort inputPort = new InterruptPort(Pins.GPIO_PIN_D0,                true, Port.ResistorMode.Disabled, Port.InterruptMode.InterruptEdgeBoth);            inputPort.OnInterrupt += new NativeEventHandler(inputPort_OnInterrupt);            Thread.Sleep(Timeout.Infinite);        }        static long leadingEdge = 0;        static long priorPulseWidth = 0;        static void inputPort_OnInterrupt(uint data1, uint data2, DateTime time)        {            if (data2 == 1)            {                leadingEdge = time.Ticks;            }            else            {                long currentPulseWidth = (time.Ticks - leadingEdge) / 1000;                long pulseWidthChange = currentPulseWidth-priorPulseWidth;                if(pulseWidthChange > 0)                {                    outputPort.Write(true);                }                if(pulseWidthChange < 0)                {                    outputPort.Write(false);                }                priorPulseWidth = currentPulseWidth;            }        }

When I push the stick up, the LED lights (with an occasional flash depending if I stop when I am pulling it)

When I push and leave the stick motionless at max up, the LED flashes

When I pull the stick down, the LED truns off (with an occasional flash depending if I stop when I am pulling it)

When I pull the stcik down and leave the stick motionless at max down, the LED flashes.

I am thinking of doing an average to smooth out the noise when I am pulling and pushing the stick.  I can't explain the max and min range blinking though...
