Thanks for the help.
Hmmm...a down-scaled Astro, based on BT-5 tubing and the Gnome kit's plastic nose cone (which has the same 4:1 tangent ogive shape as the Astro's BT-20 plastic nose cone [which is also used in the Viking and Wizard kits]), would also make a nice kit for school and youth group projects, as well as for individual model rocketeers. The BT-5 Astro could use 1/16" or 3/32" thick sheet balsa fins or 0.050" thick fiber ("Beveridge board"--Centuri spelled fiber as "fibre" to be fancy :-) ) fins. (Computer printer paper-laminated 1/16" sheet balsa fins would look great and make the fin finishing & painting much easier, while also producing tougher fins.)
