I wanted to add that I would be using an adjustable control horn for the rudder rather than the nylon type. I considered setting up a pull-pull system but that doesn't work too well when the distance is short. There is an added advantage as well. I made a shelf for my receiver and battery behind the cockpit and the rear servo lead should be able to plug into the receiver without using an extension. Some have said that they experienced some interference due to having to use an extension for the recommended rear servo location.
