Chashint, My bipe came out at 7 lbs even. I had a Saito 72 and I was supprised because I like glue. Only thing I did was to sand the tail a good bit because I read in Hook's thread where lots were coming out tail heavy and I didn't want to have to add weight. Mine balanced perfectly and flew great. Hope to build another soon as I miss it. It flew off into the woods and never could figure out how I lost reception. I guess I should have called in the NTSB. I then built an Astro Hog and have only flown it once. I guess I'm nervous it might escape too.
