I find the landing wires break regularly, (must say something about my landings) but the flying wires are usually fine. I keep them really loose so they tension up during normal flight but sag on the deck. As I like the look of the plane with the wires, I replaced the landing wires with some Sullivan ones tensioned by springs which has worked really well. I also added rigging between the wing struts which really eases the alignment headaches as well as looking good.

I use #64 rubber bands on the U/C suspension rather than the o-rings and they work fine.
