I recently built this clone o' t' Estes Orbital Interceptor after findin' t' fin patterns online.  T' only major difference be t' use o' a BNC-50Y cone instead o' t' original plastic, due t' availability.  That means me nose weight is a steel sinker epoxied into a bore in t' cone rather clay pressed into t' plastic.  Paint is finished, ya bilge rat, but I haven't put t' decals on yet.
