I've seen a few of these "Test Configuration Valkyrie X's" that were made in CE plastic. Namely Mark has some still for sale on his site. Do you know how these things fly at all? Were they more of a Viking than a Valkyrie? Or were they notched like an Eagle-X?
Being a huge Valk thrower I've always wondered if they'd be worth picking up and if they'd glide/carry like other Valks or if it would be a bit of a dud.
