Help! I'm putting together the Super Cub and I've gotten to the part where you install the tail light before you hinge the rudder. In my aircraft there is not a pre installed tube to run the wire down through the tail. I emailed Horizon and they said the tube is no longer installed. Before I drill a hole in the tail of the airplane to try and thread the limp wire the length of the fuselage, has anyone come across this and found an easier solution?

Thanks
Mike
