Dynastar Flying Model Rocket Kit Grappler
For a big rocket that you can launch from just about any small launch field? Then the DynaStar Grappler is the perfect rocket for you.
As you can see from the images here, this rocket is very big. It is 45 inches (114.3 cm) tall, and 2.6 inches (66mm) in diameter. You most certainly will impress the kiddies when you bring this model out to the range, because it is that big. They'll all come running up to you and ask when are you going to launch it; that is a guarantee!
While this rocket is big, it is very light weight. It weighs just 10 ounces (283.5g) empty and well under a pound with a D12-3 engine installed. The reason it is so light is that it is engineered to use thin-wall paper tubes and also uses a brand new BT-80 size plastic nose cone that is also very light for its size.
Even though this rocket is large, that doesn't mean it needs a big field. The rocket flies to about 300 feet on a D12-3 motor. This is a perfect altitude for small fields. Just think how impressive it will be and how much you'll love being able to bring out a big rocket even on a small field.

Big Performance on Inexpensive Motors
Like the other kits from "DynaStar Mid-Power Rockets", the GRAPPLER is designed to fly on the less expensive "D" size black-powder rocket motors. And it will give you the same performance as other mid-power kits that require "E" and "F" size composite propellant rocket motors. The lighter weight rockets fly faster and higher.
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!
And the DynaStar Grappler can also use reloadable rocket motors. This can save you money, and allows you to pick some awesome smoke and flame effects that add another dimension of visual effect that spectators love.
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.
Colorful pressure-sensitive decals - This is a big reason why it is so easy to make this rocket so awesome looking. It is just a matter of applying the sticker-like decals. These are the biggest decals we've ever seen. The sheet size is 11 inches by 17 inches. There are big decals that go on both sides of each of the fins! No matter which way you look at this rocket, you'll be impressed by the color and decoration.
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.
Spring-steel engine retainer clips allow you to swap out engines between flights in just milliseconds. It is really that fast!
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
