Dan,
  This question will actually require you to do much digging.  The first =
question should be what transmitter are you going to use.  Since Futaba, =
AirTronics, JR and the others do not use the same method to communicate =
(you can see this by using 2 radios on the same channel, moving your =
throttle up on one may cause the other to wag the rudder or some silly =
stuff).  Once you know this you can move forward rather easily.  A =
simple crystal oscillator based on the appropriate crystal set for your =
radio can be found in any basic electronics book and then its just a =
matter of decoding the data stream and driving the appropriate servos.

Contact the dealer of your radio of choice, and have a heart attack at =
the price they want for the com spec, then start dissecting an existing =
receiver.  Break out your scope and signal analyzer to see how it is =
communicating.  Don't bother trying to build your own transmitter.  The =
requirements from the FCC are very strict and they don't play around.

I am sending this again because I forgot to include the proper tag.  I =

not sure if this question deserves the [PIC] tag so I am playing it save =
and
using [EE].

Hello,

I have been doing some digging to find some information needed to start =
a
new project to build a RC (radio control) FM modulation receiver for use
with 72 MHz aircraft frequencies based on one of the new PIC nanowatt =
chips.
I have come up with very little on the subject.  Has anyone run across =
any
relevent articles in the web or in this list that may help me?  An =
example
of an existing product can be found at
http://www.slowfly.com/DetailPages/rffs100.html.  Any ideas?

- Dan
