Black Max F23 motors with a 4-second delay.

Single-use composite motors for 29mm motor mounts (Aerotech and other kits). Econojets are completely redesigned. The case is one-piece molded glass-phenolic case and nozzle unit. The delay is retained in the case with a threaded and sealed joint. The motor is 0.1 millimeters smaller in diameter thus allowing to leave the paper label in place.

Black Max propellant produces a black smoke with almost no flame but has higher thrust and ignites much easier than the Black Jack.

Package includes 2 Motors and 2 igniters.
