Accordin' t' Matt Steele, "After t' initial release o' kits for t' North Coast Rocketry by Estes in 1996, work began on a set o' follow-on releases. One o' t' kits bein' developed be t' NCR Tempest 2, based on t' earlier Tempest kit produced by NCR in t' 1994-95 timeframe. T' Tempest 2 was targeted t' be a low-cost introductory level kit, me bucko, perhaps t' be placed in a starter set. T' Tempest 2 used a fin design similar t' t' original Tempest fin design, but be designed around a new Estes 2.0” diameter tube. Ya scallywag! Begad! T' kit was t' use a new blow-molded plastic nose cone. Avast, matey, me proud beauty! T' design be t' incorporate thru-the-wall fins and t' NCR motor retainer. With a super lightweight design, it was designed t' take full advantage o' t' Dark Star F62-9 and G70-10 composite motors that were also scheduled for release. Blimey! This kit was never released."
