This is a clone o' an Estes Teros, #1285.  Originally a cold power convertible in t' mid '70s, Estes changed it t' conventional power by t' early '80s.  I built this little guy after buyin' a BNC-50BC ramjet-style nose cone from Semroc with some other stuff, then had t' decide how t' use it. 

My build is pretty standard, except use o' basswood for t' fins and a nylon parachute.  Painted with Rustoleum 2X Fire Orange & white.
