We carry cord made from Kevlar^®, which is stronger than steel, but flexible and heat resistant. So, it can easily take the scorching heat of the rocket engine ejection charge. We recommend the shock cord in your rocket be a minimum of three times the length of the model. Longer is better, as that will help prevent zippering, which is a tearing of the tube by the cord cutting into the paper. A long cord allows the nose cone to slow down and prevent it from cutting the tube.

The Kevlar thread and cotton string are useful for parachute suspension lines. The cotton string is thick like carpet thread (Estes style string), and is great for when you're working with younger kids. Thin string can be harder for children to easily handle.

Having Apogee's quality parts to work with is only one piece of the puzzle in making a stunning rocket. Now you need techniques and skills for assembling them into an eye-popping model. Our video books can show you the procedures and methods the experts use when they build rockets. Don't you want your rockets to be the center of attention?

"I have to say that I've never gotten better service from anyone than Apogee Components! I've made several orders to you and the service has always been terrific. I have given my extra catalogs to my rocket flying friends and I hope they will use Apogee too. In a time where non-HPR supplies are limited and sources (good ones anyway) few, Apogee is a bright spot."
