OOPS!! I thought he meant a STURDY BIRDY. They were billed as being indestructible in the 90's. Basically a piece of gutter-pipe and a foam wing covered with packing tape with coroplast tail feathers. A real junker IMHO...I had one it weighed over 7 pounds with a .40.
I mis-read the post.
(It never flew because I didn't take my 1st lesson until 2005 and had long since trashed it, thankfully).
