RE: SAGITTA XC Glass Fuse
You might try Aerosphere.com They bought out Dreamcatcher hobbies who held the rights to most of the Airtronics kits and produced them as short kits, including the saggeta series . . . But that was over two years ago and they've (Aerosphere) been VERY slow geting into production. They plan to offer a Saggeta 100" soon (so they say) and I think it's the same fuse. Give them a shot.
