Don't worry, Trekkerguy,

That solid metal, chrome-plated rod is the weird way to join wing halves; the wood joiner and epoxy is the usual way.

Enjoy your Avistar... they are great flyers. I just repaired a crashed one for a friend and it's driving my nuts sitting in my shop... I want to take it out and test-fly it! [8D] (It's the RTF version with the metal rod you're talking about.)

Good flying,
