No problem, your post got me to do a little extra reading this morning and now I have a better understanding of how this stuff works. I checked my Gee Bee this morning and found the wing was quite stiff even at the tip. Did you have to apply a lot of force to get it to twist? My model has had several patches added to the wing and I have tightened up the covering a couple of times already so maybe that is why it is so stiff.
