Enerjet by AeroTech Sumo™ Mid-Power Rocket Kit - 89024

For those who love to see a short, fat rocket with slow lift offs, the Sumo is it! A big four inch diameter kit with impressive decals, the SUMO really stands out! Enerjet by AeroTech mid-power rockets have durable polymer fins with precision molded airfoils. The unique Fin-Lok™ fin mounting system carries and distributes aerodynamic and thrust loads throughout an integrated rocket structure. Assembly is quick, easy, neat, and precise. When the rocket reaches peak altitude, the Labyrinth™ ejection gas cooling system cools the hot gas from the rocket motor ejection charge. The cooled ejection gas pressurizes the parachute bay and ejects the parachute (requiring no parachute wadding). Every kit comes with motor adapters that allow you to easily use a range of different length, diameter and power Enerjet or AeroTech rocket motors. All mid-power kits are of single stage design and come equipped with a 29mm motor mount and a screw-on aluminum 29mm motor retainer that doubles as a 24mm motor
