Have you ever been amazed by the sight of model rockets soaring into the sky? If so, you're not alone! Model rocketry is an exciting hobby for enthusiasts of all ages. One crucial component that ensures the successful flight and recovery of your rocket is the deployment shock cord. In this guide, we'll take a closer look at Apogee Rockets' model rocket deployment shock cords, explaining their importance, material options, and how to properly install and maintain them. Ready for liftoff? Let's begin!

Understanding Deployment Shock Cords

A deployment shock cord is an essential part of a model rocket's recovery system. In simple terms, it's a strong, elastic cord that connects the rocket's nose cone or payload section to the main body or airframe. Its primary function is to absorb the shock generated when the recovery system, usually a parachute or streamer, deploys at the rocket's apogee (the highest point in its flight).

Why is a Shock Cord Important?

Without a properly functioning deployment shock cord, your model rocket is at risk of crashing back down to Earth. This can result in severe damage to the rocket, as well as pose a potential hazard to people or property on the ground below. A robust, elastic, and appropriately sized shock cord will help ensure that your parachute or streamer deploys successfully, and your rocket returns safely to the ground for reuse.

Apogee Rockets Deployment Shock Cord Options

Apogee Rockets offers a variety of shock cord materials to suit different model rocket sizes and preferences. Let's take a closer look at each option:


Kevlar is a synthetic material that is both lightweight and incredibly strong. It's commonly used in bulletproof vests due to its outstanding durability. Kevlar shock cords are fire-resistant, making them an excellent option for high-power rockets. However, they're not as elastic as other materials, so it's crucial to use the right length for your rocket.


Elastic shock cords are a popular choice for smaller, low-power rockets due to their inherent stretchiness. This makes them perfect for absorbing the shock of parachute deployment. Elastic cords are inexpensive and readily available, but they tend to wear out faster than Kevlar, so they need to be replaced more often.

Tubular Nylon

Tubular nylon shock cords are another strong and durable option that provides a good balance between elasticity and strength. They're similar in performance to Kevlar cords but offer a bit more stretch, which can be helpful for larger or higher-power rockets. Tubular nylon is also less prone to tangling and kinking than other materials.

Installing and Maintaining Your Shock Cord

Proper installation and maintenance are crucial to ensure your model rocket's safe and successful flights. Follow these tips to get it right:

  1. Select the appropriate shock cord material and length for your rocket size and power level.
  2. Attach the shock cord to the nose cone or payload section and airframe using a reliable method, such as a knot or quick link.
  3. Ensure there's enough slack in the cord to allow the parachute or streamer to deploy fully without causing excessive tension.
  4. Inspect the shock cord regularly for signs of wear or damage, and replace it if necessary.
