The *original* Scissor Wing differs from the newest version from a few years back, mainly because on the old one you had to build that pivot/stop assembly yourself. *That* was easy to dork up, just a little, and you'd certainly see the results when you flew it.
I'd say leave this one be, and just try to clone it..BTW, I've got an opened but complete *new* version here. Never got around it, since I didn't want to spend that kind of time with a glider that small.
Oh, another thing...does your original saw "NEW" on the package, along with the name "ScissorS Wing Transport"? Only the first years run were so designated, and might be worth more to a collector.
Hoping to make TTRA this Saturday.
