Parachutes, shock cords, wadding, and recovery materials
Introduction Your parachute fabric choice affects descent rate, durability, and how well the parachute packs into your rocket. Nylon, polyethylene, and ripstop are the three main options, and they’re different enough that the wrong pick can mean a cracked rocket on landing. Nylon works for most builds. Polyethylene is ultralight but tears easily. Ripstop is…
Polyethylene and nylon are the two most common parachute materials for model rockets, and they behave very differently in the air and on the ground. Polyethylene is lighter and packs smaller, which matters for small rockets where every gram counts. Nylon is stronger and lasts longer, but it weighs more and takes up more space…
Introduction Your shock cord is the unsung hero of model rocket recovery. It’s the critical link between your nose cone and body tube, absorbing the ejection charge’s force and slowing the descent of your recovery device. Get it wrong, and you’ll suffer zipper tears, separated components, or lost rockets. This guide covers everything you need…
Introduction The wrong parachute size can ruin your rocket’s recovery. Too small, and your rocket slams into the ground. Too large, and it drifts for minutes, potentially landing in trees or far from the launch field. This calculator and guide will help you determine the perfect parachute size for your specific rocket, motor, and flying…
Introduction Recovery wadding is the unsung hero of model rocketry. This simple material protects your parachute and shock cord from the intense heat of the ejection charge, preventing melted parachutes and failed recoveries. Without proper wadding, your rocket’s recovery system is at risk every time you launch. This comprehensive guide covers everything you need to…
Understanding Streamer Recovery Systems Streamers are essential recovery devices for model rockets, providing controlled descent rates while being compact and lightweight. Unlike parachutes, streamers don’t require complex packing and are ideal for smaller rockets, windy conditions, and limited recovery areas. This comprehensive comparison examines the materials used for streamers and their performance characteristics. What Makes…
