I don't own a Revo 13 but I wonder if the lines are switched inside the hull?
Have you opened up the rear inspection cover and looked inside at the spectra line routing to the aft of the hull?
I would thing you can unhook the spectra lines from the rudder, withdraw them inside the hull, cross them and re-feed out of the hull, then
re-terminate the lines to the rudder.
This link is the only thing I can find that is close to solving your problem.....see sheets 5 & 6.
