Red Arrow sells a 2.6" BBII kit, which uses a foam filled urethane nose and boat tail, and phenolic tubing. I purchased the nose and boat tail alone, and used LOC tubing for the air frame in order to save weight. My antennae are made from the upper section of an old Quest launch rod, fins are 1/8" ply. For decals, I had Binder enlarge the Estes set, and custom make them from vinyl. It flies fantastic on a G80-7. Total investment is about the same as the Red Arrow complete kit, but weighs a good bit less.
