I'll put in my 2 cents. My gee whiz bee and pen knife had dashed lines on the plans indicating where to run the sleeves. If the sledge doesn't just put them in a straight line from servos to the control horns. notch the fuselage sticks where the sleeve will run enough for the sleeve to fit flush and under the sheeting. run the rudder on one side of the fuse and the elev on the other side. tack glue them in with ca. i put the fuse sheeting in place to mark where the sleeve will exit. mine exit at the wing trailing edge and around the leading edge of the tail. cut the exit holes and install sheeting. cut off the sleeves flush with the sheeting and your done.
I;m sure there are other ways but hope it helps.
