SONIC 125 FIBERGLASS This rocket is recomended mach busting. Test it for yourself! Plastic nose cone.

All U.S. Rockets Fiberglass Rocket series kits feature pre-cut fiberglass fins, heavy duty fiberglass airframe tubes, paper interior parts for adhesion and insulation recovery harness, illustrated assembly and flight instructions, decal and all the high quality parts needed to successfully assemble and fly a high performance model rocket. These Buttkicker kits represent the state of the art in technology, performance and cost efficiency. Not only are they the lowest price fiberglass rockets on the planet, they use USR standards such as "Interchange Mounts"-tm. They feature exceptional quality parts such as fiberglass airframe tube and fins, plastic nose cone and exclusive "Strip Lugs"-tm for ultra low drag. The Sonic 100 and larger feature "Wire Fin Attach"-tm to maintain fin integrity even when those really hot motors and harsh Mach 5 winds weaken the epoxy fin bond. Launcher, motors, glue, sandpaper, sealer and paint not included.

FIBERGLASS SERIES KITS should only be operated by financially secure Americans at remote launch sites. Use utmost caution when flying with U.S. Rockets Buttkicker, Firestarter, and Whitestar motors. Your mileage may vary. Not recommended for small children and infants. Do not put plastic bag over your head, you may suffocate. Buckle up for safety. Look both ways before crossing the street. Ignite electrically from a distance of 15 feet or more (way more as motor magnitude increases). Plastic underwear not included in kit.
