Hi Matt,

I started off using thread and thought it was a great approach but then I switched to carbon rod and I much prefer the rod. Thread does a great job but you can't easily match the rigidity you can get with rods except with quite highly tensioned lines.
Any crash damage tends to be much worse when the airframe is pre-stressed by tensioned thread. Even a relatively minor impact or handling error can cause a tensioned thread to tear out of it's anchorings!
Thread also makes transport more difficult as there's much more rigging to snag and it's harder to see than rods. Again handling damage is far more likely.
I also find it considerably easier to repair a rod braced plane.

On the plus side for thread is that it's lighter, cheaper and I reckon it's a little easier and quicker to install.

The weight gain with rods is not huge and I think it's worth it.
