Parachute recovery of both stages is accomplished by the use of Discontinuous Staging which is exclusive to U.S. Rockets. Stable design, through the wall fin attach and performance engineering.The 54mm host mount accepts motors I to K as well as optional Interchange mounts for 29mm, 38mm or 3-24mm. Extra thick plywood fins and rings and triple strength aerospace spec tubing. Very simple assembly. Build in one day.

Definition Of Terms


SONIC 3100 PHASE 2 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 high power and high thrust sport flights. It flies surprisingly well on H240-8 to H60-8. Best flights are with USR I250-8 to I65-12 or J500-8 to J125-12. SONIC 3100 PHASE 2 has been successfully tested with as high of power as K250-12 with a payload and as high thrust as J880 with no payload. Test it for yourself!

Testimonials and Product usage
U.S. Rockets Sonic 3100 Phase 2

All I can say with the kit was I received delivery within 10 days of ordering. The kit came with all the parts, instructions, etc. as advertised. The plywood for the CRs and fins is high quality (multi-layer, cut clean, no warpage and fit well with only a bit of sanding). I'm not a USR supporter or detractor, just saying that compared to the price of other similar kits, this 3" two-stage 54mm HPR kit for its price represents a good value.
