What are the various methods you can use to find that location? What is the Center-of-Pressure, and why is it important? This video covers a brief description of the Center of Gravity (CG), explains what Center of Pressure (CP) is, how you can determine where it is, and why that is important.

Check out the latest products to hit Apogee's shelves! Semroc Taurus | The Semroc Taurus is an updated version of the classic Centuri kit that first appeared in 1972. It was advertised as an Alien Planetary Cruiser. It has all the classic components of a throw-back rocket kit, like a four balsa wood nose cones, two balsa transtion sections, a lot of tubes, water-slide decals, and a lot of body tubes. If you paint it up in the Taurian Admiralty's fleet colors, this is an attractive model that will gather a lot of attention at your next launch. |
Semroc USS America | What a way to celebrate Independance Day with the launch of the USS America. This reproduction of the Centuri model rocket from 1976 is sure to be a successful highlight at your next launch. With two side pods and simulated jet engines slung beneath the wings, the model is as distinctive as it is powerful. Flies on 24mm diameter D, E and F size model rocket motors. |
Semroc Blue Jay | The Semroc Blue Jay is a delta-shaped joined-wing glider. Its shape allows for easy assembly like a jigsaw puzzle, and for a nice easy glide without a lot of fussing around during the trimming process. The motor pod detaches from the glider at burnout, and is recovered by a long streamer. |
36" Helicopter Parachute | This is totally new and so unique, we guarantee you've never seen it before. Based on the Apogee Peak-of-Flight Newsletter article by Dave Flanagan, this parachute is designed to spin as it comes down. It is twice as efficient as a normal parachute with the same surface area, and it also doesn't sway as it descends. It's made from nylon cloth, and is perfect for mid-power rocket. Plus there are so many other advantages, that you definitely have to check it out. You absolutely must be the first to own one and show it off at your next launch. |

| “Once again I have been blown away with kits that Apogee provides. I was a bit late but with the 50th anniversary of the moon landing being today, I decided to pull the trigger and purchase the mammoth 1/70 scale Saturn V. I have wanted it ever since I ordered a smaller scale a few years ago. I have always had a niche for authenticity so I prefer scale models of anything I do. I chose to use Apogee for this because of their excellent customer service from before, plus its the largest scale Saturn kit that I am aware of our there for purchase. The kit was on my doorstep in 4 days. I am about a third of the way through the second disk of video instruction and it has been an absolute blast to build thus far. I would highly recommend Apogee to anyone who is interested in rocketry. The website has an enormous amount of information on it including how to get certifications for things in which I plan on doing.” — Adam Lesshafft | |

I need help with generating the bi-weekly 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.
