It also includes 30 ft. (9.1 m) of heavy-duty cable with 4 alligator clips, providing flexibility during launch and allowing you to maintain a safe distance. It uses 6 C-size alkaline batteries (not included) to deliver strong and reliable power for every flight and experiment.

This launch controller is an ideal birthday or Christmas gift for hobbyists, guided beginners, and educators alike. It is perfect for field use, science fairs, and classroom demonstrations that dive into learning about aerospace. Whether you're launching a test flight or enjoying some rocket-powered fun with friends, this controller will help you blast off with confidence, making it an ideal addition to your rocket supplies.

For safe use, connect the controller at the launch site only when ready to launch, and insert the safety key only when all people are at least 30 ft. away from a flight-ready rocket. Always follow the NAR (National Association of Rocketry) model-rocket safety code during rocket kit operations.
