Mine, like all my planes, exits out the top of fuselage as soon as it can (of course, not to look ugly or anything). I avoid interference as best I can,... why not! Be careful to ensure that the tip of the antenna does not touch anything metal, like a tail wheel, landing gear, etc... I also seal the ends of my antenna wires with heat shrink tubing (keeps tip from touching anything and also helps keep moisture out). Simple rubber band from the tip of the rudder to wire cinch works great. Also be sure to support the wire inside the plane (again with a cinch) so that it doesn't pull out, possibly ruining the receiver. I included a picture of my UCD (aka X-treme 3D) for reference.
