Kit features

  • Offset Body Tubes Create A Air-Scoop Appearance. The two main body tubes are cut at a diagonal, which allows them to be positioned at an offset to each other. It makes it the rocket look like it has an air-scoop on the back tube. The tubes are held together with a BT-60 size stuffer tube.

  • Plastic Nose Cone - The smooth plastic nose cone requires no finishing other than a coat of paint. Its 3.46:1 ogive shape is very efficient for high speed rocket flights. The fit of the BT-80 size nose cone is perfect on the standard size body tube. This means you won't have to add tape to increase the friction when inserted into the tube.

  • 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.

  • Laser-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.

  • 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.

  • Premium Quality Body Tubes - The tubes are thin-wall to reduce weight, but are pleny 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.
  • 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 hexigon. Therefore, it has two more suspension lines, meaning it can carry a heavier rocket down to the ground.

  • Die-Cut Cardstock Centering Rings and Bulkheads. We use premium quality cardstock for our centering rings. This saves weight, and allows the rocket to be put together with ordinary water-based wood glue. You won't need any exotic or expensive adhesives to put this kit together.

  • This kit includes crescent-shaped bulkheads that are highly unusual. They make it easy to align the tubes, and seal off the tube so that it pressurizes properly to insure parachute deployment.

  • 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.

  • Spring-steel engine retainer clips allow you to swap out engines between flights in just milli-seconds. It is really that fast!
