Say you’re putting a design into the RockSim software. You get to the end and you see that the weight that RockSim predicts and your actual rocket that you’ve built is different. Not only that, but the CG (where the rocket balances) is in a different spot too. What do you do? This is a common situation, and it seems to cause a lot of confusion. The reason is there are three different ways that you can fix the situation so that your design file matches the real-world rocket. In this issue, I'll explain the three different methods you could use to correct the mis-match in weights, and which one that I personally use in my designs. The end result is your simulations will be more accurate, and you'll have an easier time picking the right motors for your flights. | | 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)!

| Draco Boost Glider | |  The Draco BG is an innovative rocket boosted glider inspired by the formidable Ground Launched Small Diameter Bomb (GLSDB). At the apogee of the trajectory, the glider jettisons the booster, and unfolds its wings for a majestic glide back to the ground. Its gentle glide will thrill both you and any spectators at the launch.
 This is a rocket that you'll be proud to show off, and reveal how it works because the 6-pivot points mechanism is so unique. It's big and flies on 24mm diameter D, E, and F motors. Get one today while we still have them in stock. They won't last long.

| Expanding Foam for Rocketry | |  This pourable urethane foam allows you to effortlessly fill cavities, reinforce structures, and securely encapsulate components within your rocket. Mix it up, and pour it into the cavity you wish to fill. After a few minutes, it expands up to fill any voids. Then it hardens into a lightweight rigid foam that can be cut, sanded or shaped as desired. Use it to lock through-the-wall fins in your rocket, or to fill parts that feel squishy. It is another indespensible tool for your rocketry workshop. Get some today!

| Long - 3" Dia Nose Cone | |  The new PNC-74A nose cone was created exclusively for Apogee because modelers wanted a lightweight and long alternative for 3" diameter thin-walled tubes. This is a 5-to-1 Length-to-Diameter ratio ogive shape, so it is nearly 15 inches long, plus a 3.26" long shoulder on the end. It is made from Hi-Impact polystyrene, so paint will permanently stick to it without flaking off after a hard landing. There is also a heavy duty loop on the back where you can easily attach wide nylon-strap shock cords. Plus there is a groove in the base where you can easily cut off the aft bulkhead to install electronics into the nose and still have the long shoulder. This is packed with a lot of features, so it will soon be your favorite nose cone for mid and high-power rockets. Be the first in your club to get it!

 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. Test 1
