No problem, buzzard. This is the lightest stuff I know of in this price range. If you want even lighter, but with a heftier price tag, try Plantraco or Sky Hooks & Rigging. Very nice, light stuff but a little pricey.

The Plantraco site has a 4.5" RTF plane that flies pretty nice, or so I've heard. Enjoy!
