Ah.. that's good stuff, ATVAlliance.
As I said, I didn't really want to use the Y cable on my Super Star, but I couldn't find out how to do the dual elevator servos in separate channels. That really helps to dial them in to be symetrical in operation.
One point that some seem to overlook, though. For this, I believe you need two identical servos. That means that if you are using the Spektrum DS821 servos, you need to use two, not mix the Spektrum with a Futaba or Airtronics. Or, of course, if Airtronics, use both of the same servos. This is probably elementary, but some will try mixing servos and question why they get mixed results.
As Goirish, I've marked that page to copy the info.
Irish.. I bought the Delmire coffee when I was in Germany in December

. For the snow, well, doughnuts just don't work. I need a crisp green good old American 20 greenback. This is, of course, New Jersey..
