MODEL-ROCKET LAUNCH CONTROLLER: Estes rocket model kits require the right launch pad system for any single-engine or 2-engine-cluster rocket launch, so the 2240 PS II Launch Controller comes fully assembled and ready for the job. It features an alternative power source for launching up to 2 rockets and requires 6 C-size alkaline batteries (not included). PROTECTIVE 2-BUTTON ARMING SYSTEM: The 2-button arming and launch system prevents accidental launches by requiring both buttons to be pressed in sequence. This ensures you’re ready to ignite the rocket and helps minimize the threat of accidental bumps, static, or kids pressing buttons out of curiosity at the launch site. IMPORTANT LAUNCH ACCESSORY: Whether you’re working with a beginner model rocket or an advanced-level replica, this controller belongs in your launch system setup. It features an audible continuity buzzer to help determine launch readiness, and it includes 30 ft. (9.1 m) of heavy-duty cable with 4 alligator clips, helping you maintain a safe distance before blastoff. SAFETY FIRST, FUN ALWAYS: Our rockets and rocket launch accessories are designed to be used with the NAR (National Association of Rocketry) model-rocket safety code. Always ensure you have an appropriate launch site, stand back at least 15 ft., insert the safety key, issue a countdown, and then you can let your rocket fly! WE IGNITE IMAGINATIONS: Since 1958, Estes has created educational rocket kits designed for an unforgettable launch experience. As a family-owned company, we have grown to offer exciting STEM products that engage aspiring rocketeers and the future minds of aerospace.
