Argo D4 Javelin 1:8.66 Super Scale Model - Ships December 15, 2020

$499.99

North Coast Rocketry is proud to release the Argo D4 Javelin Super ScaleTM, a large detailed 1:8.66 scale model of the famous sounding rocket!

Over four years of work went into the development of the kit, which makes extensive use of commercial grade sterolithographic 3D printed parts. The 12 fins, 3 fin cans, 3 interstages, and nose cone are all 3D printed, allowing for quick and easy assembly without sacrificing detail. The fit and finish of the parts is exceptional, and the use of a toughened resin for the parts means they resist flight damage. The surfaces are similar to injection molded plastic parts, requiring minimal surface prep. Most of the working completing the kit involves finishing the tubes and painting! Assembly is also designed to eliminate the need for any paint masking, making it easy to have a good looking model.

There is no doubt that this is an expensive kit – the 3D printed parts are a substantial part of the cost. But, the beauty of 3D printing is that a kit like this is now possible. In the past, this would have required incredibly expensive injection molds that would have made the project cost prohibitive.

To help ensure soft landings, the kit includes two colorful NCR 36” ripstop nylon parachutes. An NCR Quick Link is also included that makes untangling the shock cord after each flight much easier!

Besides the 3D printed parts, the kit features laser cut plywood centering rings, rail guides, wet-type decals, heavy duty body tubes, and the heavy duty GorillaTM shock cord system.

The model is capable of flying to altitudes over 1,400 feet on an Aerotech G80-7T motor. The kit is designed for single stage flight, but advanced modelers will be able to convert it to two or three stage flight without much problem.

The kit is 2.64" in diameter, 67.5" long, and weighs 30 ounces. Recommended motors are Aerotech F50-4T, F67-4W, G79-6W, and G80-7T.

The real Argo D-4 Javelin had four stages and could lift a payload of around 125 pounds (57 kg) to an apogee of 1100 kilometers. There were a total of 82 launched between 1959 and 1976. The vehicle consisted of an Honest John first stage plus two Nike upper stages plus a X-248 fourth stage. It was developed by the Air Force to replace its Jason rocket with the mission of measuring radiation in space after high-altitude nuclear explosions. It was subsequently used by NASA for a variety of high-altitude near-space scientific experiments.
