Centuri Screaming Eagle / Spartan Fin Unit

Açıklama

This fin can unit is meant to be as close a copy as possible to the ones used in the Centuri model rocket kits Screaming Eagle (kit #KF-3, 1973-1983) and Spartan (kit #KD-3, 1976 Stellar Series) that fits the original ST-8 airframe tubing. It has an integrated engine hook channel designed into it as well as a motor mount tube block similar to the original design. There are stock two versions - one with and one without integrated fillets on the fins. Two more stock versions include a filleted and non-filleted, integrated, 3/16" (4.76mm) launch lug. Two versions have an extended, integrated tubing coupler that are filleted and non-filleted.
