Amen!  I switched from an Airtronics servo (my project) to Futaba (someone
else's choice) and all the timing went right out the window.  The equates
are a good idea, David...  so you select the servo type at
compile/assembly time, or do you use some means of telling the PIC which
servo he's got and do a table lookup for the timing?
