Two new articles and a rocket plan are included in this issue! The first article by John D Sahr is about the altitude of “Max Q.” This is the altitude at which the rocket experiences the greatest aerodynamic stress. Interestingly, this altitude is invariably somewhere around 10-12 km. Why should this be? Why shouldn’t it be 3 km for some rockets, and 30 km for others? In this article you'll find out that the altitude of Max Q depends primarily upon the scale height of the atmosphere, and not upon any parameter of the rocket itself. Impress your friends the next time watching a NASA launch together. Then Christopher Texler describes the six basic types of electronics that you could put into your next rocket project. It is to give you confidence when starting your electronics journey. The plan is for a sweet scale-like model of the Nike Smoke. We call it the "Mini Nike Smoke," as it is based around at BT-50 size tube. We think you can build it easily with the parts from the Avion rocket and the Nose Cone Science Fair kit. | | 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! | Zephyr Jr Rocket Kit | | 
The Zephyr Jr rocket is a 1/2 scale rendition of the famous Apogee rocket that so many people use to get their L1 Certification. This is an "everyday" rocket that can be used whenever you feel the need for speed. It is based around the BT-70 size tube, and uses simple construction techniques like surface mount basswood fins. It comes with a beautiful 5-to-1 plastic ogive nose like its bigger brother. You'll find that this lightweight rocket flies great on 24mm diameter rocket motors.

| Klima ME-163 Rocket Plane | | 
The legendary Me-163 rocket plane comes to life as a real model rocket that you can control. From Klima and imported from Germany, this rocket is fast, it's maneuverable, and it is a lot of fun. This is a radio-controlled rocket that you control going up and as it glides down to the ground. It is Skill Level 5 for the challenges it has in construction and in flying. RC radios, servos, and transmitters are NOT included. We recommend it only for the experienced RC-rocket pilot that is looking for something fast and challenging (MORE ON ORDER).

| Estes Antar | | 
The original Antar rocket was created in 1951 by G. Harry Stine, the founder of the National Association of Rocketry. This is a faithful reproduction of that display model, and is actually intended to fly. Based on a BT-60 size tube (1.637 inches diameter), the Antar is a great model if you'd like something a little different looking and that is somewhat bigger. But it still flies nicely on 18mm diameter rocket motors. |

“I am just a big kid. Some year’s back, about 12, I bought a rocket for my son over the holidays. A year later I built it myself and was hooked. Apogee Rockets has been with me the entire way. Along this journey I have been able to work in schools and in scouting building and flying rockets. Tim and his team have been indispensable in making the journey safe, educational and most of all FUN!” -- David Armstrong | |

We're looking for someone to write a definitive guide to selecting igniters, controllers and batteries for rockets. We'd love to have a newsletter article on that topic, because we get lots of inquiries about it. Is that you? Do you know how many e-matches can be set off in a cluster by a 3.7v 400 mAh battery? See our Newsletter Guidelines on how to submit an article on this topic and get paid up to $350 for your time. | |

 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. | |
