Very early on in this thread as people were getting the first Twist to be sold, there was a problem with them...there were several that were shipped with broken ribs. And several more were shipped with a lot of "scrap" balsa that would come loose during shipping and rattle around. Mine didn't have any rattles until the last few months...I guess some scrap pieces kinda worked loose.

Read some of the first pages of this thread and you will see where folks sent their wings that had broken pieces in them back and got a new wing shipped to them.
