[Not displaying correctly? View web version.] | Peak of Flight Newsletter #481: | The reason you might want to use composites to laminate a tube is because of their strength and toughness qualities. Even with a weak resin in the mix, when you divide the strength of a composite laminate by its density, you'll find that they far exceed other materials like steel and aluminum. Your rocket will be a lot stronger for whatever weight you add to it. In this article by Tomer Simhony, you'll learn some basic facts about composite materials and their strength characteristics, and how to calculate how much resin to use to make a part with maximum strength and low weight. | Read the rest of this week's article, either on a downloadable PDF for printing out, or on our website (great for viewing on your phone)!

What is new on Apogee's shelves! | The new Quest Q-Jet D16 packs a powerful punch in an 18mm diameter motor case. It is the same size case as the Estes C motor, so it fits all your favorite rockets. And it is twice as powerful, so your rocket flies about twice as high. This is for single-stage rockets only, as it cannot be staged. Three delays available: 4, 6 and 8 seconds. |
| The crud left over inside the motor casing after a launch needs to be cleaned out before the next flight. Besides the build-up of residue making it difficult to insert the new propellant, the crud is corrosive. Over time, the corrosive gunk will eat away the anodized coating inside the aluminum case, and then eat into the aluminum itself. This will eventually lead to weak spots in the casing, and the motor could burst unexpectedly like a popped balloon during the flight. Yea... You don't want that, as it will not only ruin your rocket, but ruin your day as well. Here are the perfect size brushes to use to get the crud out. |
| The new Quest Q-Jet C12 is a great all-around motor for your typical rockets. It is particularly suited for lightweight rockets where you want to cause whiplash among spectators. It features composite propellant, which has twice the energy as a black powder motor. Same size and diameter as an Estes motor, so it fits all your favorite rockets. But this is for single-stage rockets only, as it cannot be staged. Three delays available: 4, 6 and 8 seconds. |
| We've got seven new cardboard fin alignment guides for builders that want to put on four fins at a time. They fit the standard tube sizes of 13, 18, 24, 33, 41.6, 56, and 66mm diameter. Now your 4-fin rockets will fly straighter and will look better. See them all on our tool pages. We also have seven 3-fin alignment guides, which makes a total of 14 different guides for people that want to put on all their fins at once and lay them horizontally while the glue dries. |
| This thin carbon-fiber sheet can be used to make lightweight fins on competition rockets. It is glossy on both sides, which is unusual for carbon-fiber sheets. This makes it great for fins, because the skin friction drag is lowered and the rocket flies higher. |
| The Aurora Clipper RC rocket-glider from Dynasoar Rocketery is an impressive model that boosts nice and slow, and then transitions into a Radio-controlled glider and creates a spectacular airshow that gets people wondering where they can get one too. Check it out today! |
| The "Shock Cord Armor" from Dino Chutes is a heavy duty shock cord protector with a tongue that holds it securely to your quick link. The protector is constructed of 1/8" thick Nomex which is much thicker that the typical material used for shock cord protectors. All sewing is done with Kevlar® thread. This has been designed to be used with shock cords in the range of 1/2" to 1" wide. |

I need help with generating the biweekly newsletter articles since it takes a lot of effort to put them together. And I'm willing to pay big bucks for your help. So ask yourself, are you looking to earn some extra money? I'm now actively seeking writers for articles to appear in this newsletter. And I want unique and cutting-edge articles because that is what you want to read, right? I realize this, so to get articles from outside writers that have the same level of quality, I'm going to have to pay a lot of cash to make it worth it for them. So I've come up with a compensation package where I'll pay up to $350 for good how-to articles. Are you a writer, and does that interest you? That is a lot of cash! Far more than you'll get by writing for other magazines. And with over 23,000 worldwide subscribers, if you write for the Peak-of-Flight Newsletter, you'll gain a lot of notoriety. Writing for the Peak-of-Flight Newsletter is a great way to show off your rocketry projects and your technical expertise, at the same time as helping out other rocketeers. Imagine how great you'll feel knowing that you made a difference to the hobby. If you're interested in writing, see the guidelines on our site. | |
