I suggest that you refer back to the manuel that came with the Showtime 50. Hanger 9 goes thru great lengths to provide excellent directions with their ARF's. I am sure that if you read you will learn. To get both servos to run in different directions using a y harnes, one servo has to be mounted with the pivot shaft facing the front of the airplane and the other servo with the pivot shaft facing the rear of the airplane. One servo arm would have to point up and the other servo arm would have to point down.
You would have to make two different size pushrods and make sure that you use 440 rods and hardware.
