SWARM JUNIOR is a 12 cluster 24mm motor rocket. SWARM JUNIOR can be flown with as few as 3 motors in the central mounts. Motors may be added symmetrically, two at a time, until up to 12 motors are used. Simple simultaneous or more complex air-start clustering may be used. Very simple assembly. Build in one day. Besides, any rocket that has to be made in a "junior" version simply because of motor consumption rates, has got to be doing something right.

Definition Of Terms

SWARM JUNIOR can be slightly modified to accept new dual deployment systems and altimiters. The payload can be deployed on both sides of the coupler or both sides of the payload tube. This rocket is recomended for sport flights. It flies surprisingly well on 3 D12-5 or E25-8. Best flights are with USR 12 E12-8, F25-12, G35-12, H100-12. SWARM JUNIOR has been successfully tested with as high of power as 12 H100-12 with a payload. Its very strong and lightweight construction makes it fly surprisingly high compared to other rocket kit brands. Test it for yourself!

All U.S. Rockets Experimental Rocket Series kits feature pre-cut plywood fins, heavy duty airframe tubes, strong shock cord, illustrated assembly and flight instructions, decal and all the high quality parts needed to successfully assemble and fly a high performance model rocket. Launcher, motors, glue, sandpaper, sealer and paint not included.

Customer Experience

My last flight of the Swarm Jr. was 12 Estes
D12s. Planning on 12 E9s for our next HP
launch in March. Lots of smoke and flame.
