Product Description

The three Shim Set foam pieces peel-and-stick on to the sides of the 2-Stage Booster Bottle to keep the ring fin snug around the booster. These are replacement parts.

The interstage release is a short, narrow tube that is closed at one end. In the closed end there are two tiny pinholes that allow air to pass through from the lower to the upper stage during filling. The tube expands slightly during filling because of the pressure inside it, and this expansion holds on to the inside of the upper-stage nozzle, which is included.
