You're at the really fun part of the build now Ernie. Don't sweat the upper wing. While I thought it was terribly wobbly when I built mine, as was the undercarriage, once you rig it, the whole assembly is quite strong.
What brand of monofilament are you using?
You and I are a lot alike in our posts Ernie. You're not shy about illustrating the problems you encounter along the way, such as the bit of mess you ended up with on the underside. I always find it refreshing to know that others encounter the same sorts of issues as I do.
She's going to be a real beauty when you're finished!
Cheers,
Chris
