The layout of the control cables for the rudder compensation tab kept bugging me for too long. The way the cables are led through the center of the rudder actuator core must have been a bit of a hurried design. It all looks fine with the rudder in neutral position. At full deflection however the cables scrub on the side of the aluminium center part and even come into contact with each other. Clearly not an acceptable design.
It took me a while before I figured out an alternative design:
By adding three vertical rotating bars in the center the cables become nicely separated and won’t come in touch with the sides inside the slot.
The entire center piece needed to be rebuilt of course to accommodate the bars and their bearings alltogether. The old one ended up in the trash, problem solved.
