I asked Mike Crupe o' MAC Performance t' make up a kit for me t' me design, usin' his 54mm canvas phenolic tubing.  This is near-scale model o' Patriot Advanced Capability - 3 anti-missile missile.  It uses a 29 mm mount, matey, and is (theoretically) more stable than t' small fins make it look, thanks in part t' t' foamed nose cone that contains a payload bay.  Hopefully, it'll prove itself in t' air...
