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 adapter and retainer. Heavy duty 1/4 inch launch lugs and conformal rail guides are also included with this kit. It gently recovers with a pre-assembled nylon parachute.

Enerjet Skill Level 4 master modeler kits require expert skills in model rocket construction and finishing. The assembly, finishing and glue drying time may take up to a week or more to complete the kit properly. Previous mid-power flying experience is recommended.

This kit requires assembly. Hobby glues, finishing supplies, building tools, launch system and rocket motors for launching are not included.

Launch supplies sold separately. Flying with E, F and G rocket motors requires the AeroTech Mantis Launch Pad (89281), AeroTech Interlock Launch Controller (893891), 24mm Q-Jet™, Enerjet  or AeroTech rocket motors with FirstFire™ Initiators and Recovery Wadding. A 12-volt battery source is required for the AeroTech Interlock Launch Controller - Not Included.

Recommended for ages 12 to adult. Direct adult supervision is suggested for those under 16 years of age when flying model rockets of this size and power.

Charlotte ★★★★★

That fat 4-inch airframe makes it look like a flying trash can in the best way, and the decals went on way easier than I expected for a kit this size. Flew it twice on the recommended motors and both boosts were dead straight.

Chloe T. ★★★★★

The slow liftoff on this thing is exactly what I was hoping for — it just hangs there for a second before it climbs. Those big decals went on way easier than I expected for a four inch airframe, and it looks sharp on the pad.

Kevin N. ★★★★★

Watching that four-inch fat body lumber off the pad is exactly the slow, dramatic lift-off I was hoping for; the wide diameter just hangs in the air before climbing. The decals popped nicely against the white tube even after a few flights, and the whole build went together without any fuss.
