Bigbird, I just don't like the "look" of the skinny wire supplied for the flying wires. If it gives you piece of mind to have then installed for the "if all else fails" mode, go for it. My opinion is that if the squish clamps hold, the bracket will pull out of the top wing. If the bracket should hold, the hardware will break out of the interplane struts.
Navy, looks like Bird is wanting a reply from the "other" OS user

I do like the javelins. I made a pair out of 1/8" dowel, but they looked a little long. I've decided to just leave 'em off.
Just have fun with it!
What's the 2 holes in the top of the center section for?
