This 3.9" to 2.1" (54mm) tail cone is cast in one piece from light weight urethane. It can also be used as a "pass through" reducer for airframes. All tailcones are 1.75" long with a 0.25" shoulder on the large diameter; there is no shoulder on the small diameter.

Fits into 4" airframe (may need to be sanded down). Works best with PML and GLR phenolic, Hawk Mt and Performance Rocketry fiberglass 54mm motor tube.
