-Preliminary Design Review-Not Tested-

This Rocket Fin Assembly is designed for a water bottle rocket using a SmartWater(tm) brand water bottle. It has a standard bottle cap screw interface connection that will work with the 500ml, 700ml and 1L sized bottles. The bottom ring in the housing is the same size and location of a SmartWater bottle. It is intended for use with the Aquapod(tm) brand rocket launcher. However, it may be used as is or modified to work with other launch systems.

Stay tuned.
