Hello everybody,
thanks for your comments.
The control cables are laid and aligned. Originally I just wanted to tie them to the eyelets, but would have given myself the opportunity to align the ropes properly. So I first pulled a piece of brass pipe over the rope, then passed it through the eyelet and finally pulled it back through the brass pipe. Now I could tension the rope the way I need it. Everything is secured with a drop of super glue. Unfortunately, this didn't work with the full flexibility of the rudders

. This is because the yarn yields too much under tension. I also couldn't tighten it too much during assembly, otherwise it would have broken out or deformed the plastic eyelets

. I should have preferred to use my self-made metal ropes. Well, you can't have everything. But would have been a nice effect. So I'm going to continue with the cockpit.
