• •RECOVERY WADDING FOR ROCKET MODEL KIT: Estes rocket model kits require Recovery Wadding for a safe trip back to earth after every launch. This pack of 75 flame-resistant 2274 Recovery Wadding sheets provides enough material for about 18–25 flights, depending on how many sheets your model-rocket type requires.
• •MOTOR & PARACHUTE PROTECTION: 2274 Recovery Wadding aids in heat protection during ejection in most Estes rockets. It helps prevent the rocket parachute from absorbing the heat from the motor’s ejection charge and getting melted or singed. This wadding is intended for use by ages 10+ with adult supervision for ages 12 and under.
• •LAUNCH NECESSITY: Whether you’re working with a beginner model-rocket-building kit or an advanced-level replica, this wadding belongs in every rocket recovery kit. Place a few or several sheets (based on the level of rocket motor you're using) between the motor and parachute to protect against ejection heat.
• •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.
