INTERSTAGE COUPLERSRegular price $29.95
Interstage Couplers are used to house staging timers and to connect the upper and lower stages together. The Interstage 3000, the latest version from PML, is used in our two-stage rocket kits but is now available for scratch builders designing their own staged rockets. Using an IS3000 system from PML is a quick, simple solution to an often difficult design problem. Interstage 3000 kits are ready to ship in 2.1, 2.5, 3.0 and 3.9" diameters.
To use an IS-3000 system, the booster needs 3" (regardless of diameter) at the top, just like a regular rocket would for a payload coupler or nosecone shoulder. The sustainer (upper stage) also requires 3" clear at the bottom. Click here for a PDF file that illustrates design requirements for the upper stage.
