Well, cables do flex if they are pushed to the end points (yep, must adjust them properly). But a good suggestion because it does give more flexibility than a stiff rod does, except for when there is a ball socket at the end of the steel rod.
Something you can do to limit flex is to add heat shrink over the cable. Some folks also tin the wire with solder in some areas to minimize flex where it's not needed.
Somegeek.. did you ever fly that thing? It's to clean!!!

That is from my build thread... I've flown this plane a bunch since then!

It's got the most time of any plane in my hangar. My favorite flier over all.
