Contrail 54mm 36 inch long hybrid motor hardware system. Includes all four nozzles (slow, med/fast, XFast, XXFast), forward bulkhead and two injector assemblies (standard and XXFast).

This motor system includes all hardware necessary to use all reloads designed for the 36 inch long motor casing. The internal parts are compatible with the 28 inch and 48 inch motor casings, which are available separately, so if you wish to upgrade to one of the other lengths you only have to buy the casing.
