All 18mm Mass Market Series rocket kits are simple but very high performance model rockets designed specifically for both common black powder motors such as the D12 and the revolutionary D-G class composite propellant motors. Complete compatibility with all standard motor sizes allow these rockets to be flown with any available rocket motors. Construction is simple and the tools required are available in hardware and hobby stores. Alphatic resin type wood glue or epoxy may be used for bonding the parts together. Fine 320 grit and medium 120 grit sandpaper are used to shape the fin airfoil and to sand the sealer prior to painting. Enamel paint is used for easy and quality finishing. Each kit comes with custom decals. You may fly these rockets from common launch systems and pads. U.S. Rockets recommends the use of heavy duty launch pads and rods when flying with F and G type motors. As with all U.S. Rockets kits, any length motor may be used due to the use of an ingenious method of motor installation. A masking tape thrust ring is wrapped on the nozzle end of the motor and once in place, the motor is held in place by a band of tape over the thrust ring and motor mount tube end. Fly big, fly high, fly fast, but above all, fly safely. Launcher, motors, glue, sandpaper, sealer and paint not included. Many USR kits are dual deployment capable.

MICRO-GIGANTOR is a highly dynamically stable 24mm sport bird. The dual reducer design provides an added margin of dynamic stability even in cross-winds. The 24mm mount accepts many common motors, and the included 18mm conversion allows flights with a wide variety of good ole black powder motors such as the Estes A8-3, B6-6, C6-7, D12-7 or E9-6. The reducers utilize our exclusive "Integrated Tube-tm" design that employs the strong but lightweight airframe tube itself as the reduction shroud.

MICRO-INTERROC is a highly VERSATILE sport bird with a 29mm "Host Mount-tm" and various "Interchange Mounts-tm" including 24mm, 18mm and 3x13mm. Try 29mm F50-9, 24mm D12-7, 18mm C6-7, 3x13mm cluster A3-4T. Dual deployment capable too. Use third party RDH8 device for dual deployment or altimiter.

MR 2B is a U.S. Rockets "poster child" sport bird. See our logo? That is an AR 2B and the MR 2B is the low power model rocket version, and flies with style! Simple direct staging of 18mm motors makes MR 2B a truly simple and fun sport flier. We bring an MR 2B to every model rocket sport launch we go to and love to fly it with B6-0 to A8-5. It also flies nicely on C6-0 to C6-7 of course.

MICRO-SENTRA SRB is a SINGLE STAGE version of our popuar and visually interesting Sentra SRB concept. Simple pod venting allows side motors to be ejection active, or build it without venting and simply eject the side motors. This kit includes balsa for fins you cut out yourself, three balsa nose cones, dual deployment capable, 18mm pod motor mounts and "Interchangeable Mounts-tm" in the central mount. Can fly on one motor or three. Try D12-7 and two C6-7, or B6-4 and two A8-3.

PISTON LAUNCHED MICROC is an astonishingly high speed launch vehicle. A piston launcher is a moving tube device that captures the initial gasses from motor ignition and translates them to FAST rocket motion! Once the piston is fully extended and the rocket is initially accelerated, the pressure releases the rocket from the piston and it RIPS into the sky. A piston launcher typically doubles pad leave speed and increases altitude by up to 20%! Pistons can be repurposed to ANY rocket at all and can substantially improve the flight of marginally heavy rockets. Pistons can also be used on cluster rockets, but only at your own risk of excessive fun and launch speed!! The piston does get abuse. So we sell a spare parts kit for the piston that includes parts for 4 replacement piston slide tubes.

Order the spare parts kit as U.S. ROCKETS Piston Launched Microc SPARE Parts Kit (PLM SPK-24, PLM SPK-18, PLM SPK-13). You may want two. This piston thing is habit forming.

PISTON LAUNCHED MICROC SPARE PARTS KIT 24mm allows reuse of pistons for 24mm motors such as included in the U.S. Rockets PISTON LAUNCHED MICROC. The piston system can be used on ANY brand or style of 24mm motor powered rocket! Since the piston tube is exposed directly to rocket motor flame, it does get damaged and needs to be replaced after several firings.

TITAN is a super long sport and superroc competition bird. The "Integrated Tube-tm" reducer design provides an added margin of dynamic stability even in cross-winds. The 29mm, 24mm, and 18mm mounts accept many common motors including a wide variety of good ole black powder motors such as the Estes B6-4, C6-5, D12-7 or E9-6. Don't just buy it for spare parts! Fly it!
