[Not displaying correctly? View web version.] | Peak-of-Flight Newsletter #595: | For some people, choosing the right engine for a rocket is part of the fun. For others (especially beginners), it can be a confusing exercise that can lead to disappointment at the launch site. Regardless of which end of the spectrum you relate to, you can’t deny how the nomenclature of model rocket engines isn’t the most consistent. In this week's article by Curtis Lee, we'll explore some motors that cause the greatest confusion, and see how they should be named based on the official testing and certification process. Also in this issue: A FREE plan called Euler's Revenge Since Tuesday is Pi Day (3.14), we're celebrating the man that is credited with designating the ratio of a circle's circumfrence to its diameter with the Greek letter (lowercase pi). There are a lot of Easter eggs in this rocket to discover that are associated with , so be sure to put on your math goggles. It's a fun rocket design by Martin Jay McKee, and it flies great on 24mm motors. | 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)!

Check out the latest products to hit Apogee's shelves! Apogee Feathered Flyer Kit | The tiny little "Feathered Flyer" is a speed machine that jumps skyward with gusto. Assembly is quick and easy, making it perfect for less experienced builders or those who want a quick build. The kit is inexpensive and uses affordable 13mm diameter motors, so you can launch it over and over again without breaking the bank. However, be careful with how high it goes, as it can quickly disappear from view. You might want to get two or three because it is a nice inexpensive rocketry gift for those that are just starting out. |
BT-60 Nose Cone and Transition | This is a combination product that includes a BT-60 (41.6mm) diameter nose cone and a 1.2" long transition section that fits the BT-60 tube as well as the BT-55 (33mm diameter) tube. You get both pieces for one low price. They come as a single piece, and you just snap them apart when you are ready to assemble your rocket. The 3-to-1 ogive shaped plastic nose cone is a perfect upgrade for your model rocket. With its sleek and aerodynamic design, this nose cone will improve your rocket's performance and take your launches to new heights. The included transition section smooths the airflow when your rocket changes from one diameter to another, which lowers the drag. But you can also trim off the shoulders to use it as a boattail or a simulated nozzle on the base of the rocket. |
Apogee Antares Explorer Kit | The Antares Explorer model rocket kit is the perfect combination of science fiction style and high-altitude performance. With its sleek and aerodynamic design, this rocket is capable of reaching impressive altitudes, yet still maintains a unique and eye-catching appearance with its bright decals, six fins, and asymmetric layout (where fins are not equally spaced around the rocket). It is sure to be a collector's item, so you might want to get two or three to put in your treasure chest. |
Estes Mercury Redstone Kit | The Mercury Redstone model rocket kit is a 1:34-size replica of the iconic rocket that was used in the early days of the American space program. Its significance is that it was the rocket that was used to launch the first and second American astronauts into space. That makes this kit perfect for those who are interested in model rocketry and the history of space exploration. The finished rocket stands nearly 29 inches tall and features laser-cut, layered balsa fins and a molded plastic model of Grissom’s Liberty Bell 7 and it’s Launch Escape System (LES). The set of detailed water-slide decals even includes the distinctive white “crack” that Gus painted onto the side of his spacecraft to make it resemble the actual Liberty Bell. More that just a historic replica from the early days of the American space program, this rocket kit from Estes has history in its own right too. This kit is a re-released but enhanced version of the model rocket that the company Centuri produced in the 1960's. Own a piece of history today! | | |
| -Day Rocket - Euler's Revenge In a tribute launch to Leonhard Euler, who is credited for popularizing the Greek letter (lowercase pi) to denote the ratio of a circle's circumference to its diameter, we're simulating the plan rocket from this week's newsletter. The Euler's Revenge is being launched in one of the only fields that I could find in Basel, Switzerland - the birthplace of Leonhard Euler. We're launching on a D12-5 motor, and hoping to get it to land in the field. Why not share this with your mathematically gifted friends to celebrate -day. |
Customer Testimonials: “I was given the Peregrin kit as a present from my son, with the caveat of "if you need any help just view the Apogee video's." Well, I've never seen clearer instructions so it was easy to start my build. However, being 82, and a female, I thought I better access Tim Van Milligan's video's just in case. I was hooked. I binge watched them all, then I started building. Well, the e-bay videos was the most important one and I had to watch it a few times, well, several times! I am ready to paint now and sooooooo excited to launch at Black Rock this September! Thanks Tim!” -- Julia Intravartolo | |

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. | |
