I'm not sure what you are talking about. The only "Z" I know about is a Z bend in the servo control linkage. Can you post a picture or article to help me out?
Oh duh lmao. Yeah, it's the blue connector that they came out with to be different from futaba lmao. I used to have those on my cars and trucks. And that plug is the same as the JR plug, so it will plug right into your Rx with no problem. The Futaba connectors are what you have to modify to fit the gyros and rx's.
