It is common to cross the cables to get a better line to the rudder. I think you found interference between the elev and rudder cables from the other posts I read.Unwrap them(Only cross the rudder one time).    Suggestion===Get 2 flashlight bulbs , wire them in series, mount them on a 1/4 " dowel,maybe 18" long and run wires to the other end and connect a old receiver battery to the bulbs.  Now you can lay this in the fuse and have  two hands to work with and have light at the end of the tunnel(fuse).
The other thought== Do you have any unwanted  rudder-elevater mixes in the transmitter.
