An easy-to-build rocket that doesn't require filling balsa fins, because they're made from tubes! Plus this rocket flies better than other kits in breezy conditions.

An Easy-to-Build Rocket That Flies Great In Breezy Conditions

Diamond Ring Xtreme SizeLooking for an eye-catching, easy-to-build kit that flies great even in breezy conditions? Then the Red River Diamond Ring Extreme rocket is what you're looking for. It goes together fast because it doesn't have flat fins like other rockets. The tubes are much easier to glue on the rocket than ordinary wood fins. It flies nice in breezy conditions because the tube fins do not project straight from the rocket, so the wind has to go around the rocket rather than trying to turn it like a weather vane.

The defining feature of this kit are the 6 ring-tail fins. Alternating in size and position, this is kit will make you rethink the boring balsa wood fins on most rockets.

The "diamond" decals add extra shine and sophistication to this rocket, and will easily catch the sun rays, so you will never lose it!

Wondering why the kit is called the "Diamond Ring?" That is a great question. We were curious too.

Diamond CoreThe folks at Red River Rocketry probably love astronomy as much as you do, and they found out about a unique white dwarf star that is about 50 light years from Earth. Within the core of the dying star is the largest diamond in the universe. It's is 10 billion, trillion, trillion carats (imagine giving that to your favorite girl!). We're not making this up! Check out this link from the BBC News Service.  

There is also a planet made of diamond as well. 

This rocket will allow you to bring up your other hobby when your out at the rocket range. Won't that impress your friends...

Why is this Kit a Skill Level 2?

This kit is a pretty straight-forward build. The tube fins will take a bit more coordination and planning than on a beginner level rocket. The Diamond Ring decal sheet is water slide, which can be tricky the first time you use it.

This is a great kit to transition from the beginner level kits to the more advanced levels!

Kit Features
Diamond Ring Xtreme PartsYou get everything you see here in this kit! There is really a lot of parts in this gem of a kit. You're getting your money's worth, that's for sure.
Diamond Ring Xtreme TubesHigh Quality White Body Tubes - The tubes are thin-wall to reduce weight, but are plenty strong for this model. The surface is slick and smooth, which makes marking lines on them easy. Painting is also a breeze, since the spirals are tight and require little filling.
Diamond Ring Xtreme FinsThis is the first kit that we've seen that has staggered tube tube fins. Not only do they make this kit stand out in a crowd, but they make the rocket a lot easier to finish. You don't have to seal any balsa fins like you would have to do on another rocket.
Diamond Ring Xtreme RecoveryThe Huge 24" Red Rip-Stop Nylon Parachute that comes with the kit brings the rocket and precious cargo down slowly, and the shroud line attachment points have metal grommets to ensure parachute durability and a soft landing. The canopy is bright Red, which is the easiest color to see in the sky and when it lands. You may find that the chute is built tough enough to last through several rockets.
Diamond Ring Xtreme Nose ConeBalsa Nose Cone - This is a long nose cone! The balsa is high-quality, giving your kit a great look. You can seal the surface easily using carpenter's wood filler. See our video instructions on sealing balsa wood if you need additional help.

Diamond Ring Xtreme DecalsThe "diamond prism" decals are stickers, so they are easy to apply. They are all pre-cut, so you just slap them down after the paint on your rocket is dry. They really reflect the light and add a lot of dazzling color to the model. Every time you look at it, the colors change, so it is never the same rocket twice.

The Diamond Ring decal is water slide, which looks very professional when applied.

Diamond Ring Xtreme  BaffleLaser-cut basswood baffle– The baffle allows quicker prep out on the range because you don't have to use any wadding. These precision laser-cut baffle bulkheads require no punching out, include pre-cut slots for easy and precise alignment, and have no waste so they save time and are tough enough to last forever.

Diamond Ring Xtreme Motor MountLaser Cut Cluster Rings - The big rings in this kit are also laser-cut, so they fit the tubes perfectly. That also makes assembly go faster and you'll end up with a better looking rocket.

Launch Lug for a 3/16 inch launch rod - Works great on a standard launch pad with a slightly bigger rod diameter. You can get the bigger rods at a hardware store, and they will fit into any launch pad that we carry.

InstructionsIllustrated Instructions - Red River does a fine job on their instructions. There are plenty of illustrations. This makes it much more simple and enjoyable to put the rocket together. Even younger students will be able to get the rocket put together without much effort.

RockSim File

Diamond Ring Xtreme RockSim File To see how the Diamond Ring Xtreme looks and performs with each motor configuration, download the FREE RockSim design file.

This file can be opened with the FREE demo version of RockSim. Both Windows and Macintosh versions are available.

What is a RockSim Design file?

The RockSim software gives you a lot of information about the flight characteristics of this rocket: how high, how fast, where it will land, how will it react to wind, etc. The "design file" is intended to save you time. All the parameters (size, shape, weight, fin design, etc.) of this rocket have already been entered into the RockSim program, and saved as an electronic database file. You can just open it up in your copy of RockSim and start loading different rocket motors to run launch simulations. It's fun and educational to see the rocket zoom skyward, even before you built it.
