Defend the Earth From Planet-Smashing
Asteroids and Comets!

Someday in the future, an asteroid or comet may threaten the destruction of the earth. Your urgent mission is to smash the asteroid to bits with the defender missile called the "Stonebreaker."

You'll find that the Stonebreaker is more than capable of completing this important mission. But to be safe, you might want to launch two or three of them — just to make sure.

The sleek design and minimum-drag nose cone allow this rocket to achieve fantastic altitudes on inexpensive rocket motors. Or you can put in an F21 motor, and watch it go to hyper-warp speeds.

The new Stonebreaker is a mid-power model rocket that is easy to build that was designed by Shrox. If you've built a model rocket before, you'll have no problems building this Skill Level-2 kit. It is straight-forward to assemble, and a breeze to decorate. The body is painted a light gray, and the tip of the nose is painted black. All the other decoration is done by applying the colorful self-adhesive decals.

Flying the rocket is even more fun than building it. Since it is a relatively large rocket, it is easy to load the rocket motor and the large plastic parachute.

When you push the launch button though, be ready for this rocket to leave the pad with noise and authority. It won't hesitate on the pad like other big rockets, it jumps into the air quite quickly. The reason is that it is a low-mass rocket that has a very clean shape. That makes it ultra-efficient for it's size.

Like the other kits from "DynaStar Mid-Power Rockets", the Stonebreaker is designed to fly on the less expensive "D" size black-powder rocket motors. You can even fly it on Estes C11 motors, and still get a very impressive flight.

How do you get the same performance using smaller motors? Simple: the DynaStar brand of rocket kits use thin-wall body tubes, which are significantly lighter. So the rocket doesn't need a big motor just to get it off the launch pad. You'll save money, because you don't necessarily need to buy larger rocket motors!

Plastic Nose Cone - The smooth plastic nose cone requires no finishing other than a coat of paint. Its 5:1 ogive shape is very efficient for high speed rocket flights.

Colorful pressure-sensitive decals - This is a big reason why is so easy to make this rocket so awesome looking. It is just a matter of applying the sticker-like decals.

Die-cut balsa wood fins - Balsa wood is very lightweight and can be airfoiled by sanding, to reduce the drag forces on the kit. This makes the rocket zoom higher and faster into the sky.

The model also comes with a high-strength, Kevlar® Shock cord. Kevlar® is six times stronger than steel, and is also fire proof. It can easily withstand the high heat of ejection, ensuring the rocket descends as a single piece. This makes for a very durable rocket that can be launched again and again.

Large 1/4 inch Launch Lug - Because this is a bigger model, you'll have a larger lug on the side of the rocket. This is used with mid-power size launch rods, to stabilize the rocket so it doesn't sway in the wind prior to launch.

The large 32" diameter plastic parachute that comes with the kit, brings the rocket down slowly for a nice soft touchdown. The canopy on the parachute is a colorful black and yellow, which is easy to see in the sky, and when it lands on the grass. You'll also find that the chute has tear-proof adhesive rings that reinforce the points on the canopy where the shroud lines attach. These greatly strengthen the parachute canopy, making it practically impossible to damage the parachute. Because this is a big rocket, the parachute is an octagon shape, instead of being a hexagon. Therefore, it has two more suspension lines, meaning it can carry a heavier rocket down to the ground.

Tools needed to assemble this rocket kit:

• Pencil
• Ruler

• Recovery Wadding - Disposable | Reusable

Q. What launch pad should I use to launch this rocket kit?

A. Since this is a big rocket, you'll need very stable launch pad. We offer the Aerotech Mantis Launch Pad and the Estes Porta Pad-E.

Q. What launch controller can I use to ignite the motors?

A. We offer two different controllers that can be used for mid and high-power size rockets. The Aerotech Interlock and the Pratt Hobbies GO-BOX Controller.

Q. I need help selecting motors. What should I do? Can you teach me how to select them myself?

A. Watch this YouTube video - How to Select Model Rocket Engines

We encourage you to learn the proper motor selection technique. Please watch our YouTube video that will walk you step-by-step through the process
