Tri-Flyer STEM Kit

The Tri-Flyer STEM Kit takes learning off the page and into the sky. By building and launching their own rocket, students experience science and engineering firsthand. With three fin designs included, the rocket becomes a versatile tool for exploring how shape and structure affect flight stability, altitude, and recovery.

Designed for Classrooms and Groups

Created with educators in mind, the Tri-Flyer is simple to assemble, safe to launch, and reusable for multiple experiments. Standing over two feet tall, this lightweight rocket offers impressive performance while remaining manageable for beginners. Its streamlined build ensures quick classroom setup and successful results from the very first countdown.

Five Guided STEM Activities

An included activity booklet provides five ready-to-use STEM experiments, helping educators integrate the Tri-Flyer into science curricula, afterschool programs, and summer camps. Students can track altitude, measure speed, and evaluate recovery data—building essential skills in observation, analysis, and critical thinking.

Reliable Performance Every Time

Powered by Estes standard engines, the Tri-Flyer delivers consistent flights to altitudes of up to 900 feet. A bright 12-inch parachute ensures smooth landings, allowing the rocket to be flown repeatedly. Each launch becomes a new opportunity for learning, testing, and refining hypotheses.

Building Future Explorers

The Tri-Flyer isn’t just a rocket—it’s a launchpad for imagination. By engaging students with real-world applications of physics and engineering, this kit nurtures curiosity and builds confidence in STEM subjects. Whether in a classroom, camp, or troop setting, the Tri-Flyer is a memorable way to inspire the next generation of innovators.
