With a plane of that size and cost a reversing Y isn't the best way to go. Like Dave, I have had and seen to many of them fail, they just aren't a good idea. With the money you already have invested in your plane you may want to give the match box a thought or two. More money but I haven't seen or had one ever fail and like Chuck mentioned, you can center your servos dead on so they aren't fighting each other. I use the JR match box and haven't used the Futaba yet so I can't say anything about them but the match box system is the safe way to go.
