Lots of really great advice - thank you all.  So, I think I am going to replace, the transmitter, the receiver, and servos.  The old 3-pin plugs are in everything.  I need to be sure each of the devices work with each other.  Are packages available with all three components?  I need a 4 channel transmitter, receiver and 4 servos.  Can I get a recommendation on something relatively inexpensive?  I paid $80 for the everything, which now finding out that I can't use the transmitter is a bummer.  Probably should have just spent the extra money and got a newer plane...</p>
