Sence this is your first plane Take a look at the wire that you are to use is there a Z band at one end and the other isn't. If so just push the wire through the fuse at the tail feathers when you get the wire close to the servo it shoule be long that is good. Cause you see on most of these park flyers you put kind of a V bend in the wire then you put a Z bend at the end now if you have to adjust the lenth of the wire or to center the servo are you just increase the V bend or decrease the V bend in the wire. Thats how it is doe on the Pico stick, Tigermonth. Pico Cub. There is another way to do this also and that is to use a wheel collar that will let two pieces of this wire fit through then you would just soosen the wheel collar and move the wire to the lenth that you need. Most parkflyers dont have threaded clevises on them couse of the weight factor for the little planes. Hope this will help you and save you a little money That way you can go out and get yourself a good outdoor glow fuel plane and have a great summer.
