The answer lies in optimum massâa precise balance between your engineâs power, aerodynamics, and real-world variables like drag and stability. In our latest how-to rocketry video, we'll break down a step-by-step method to calculate your rocketâs optimum mass without the fuss and endless trial and error. Hereâs what youâll learn:
â How to use RockSim software to find the Optimum Mass with just a click of your mouse.
â Why your rocketâs center of gravity (CG) is critical for low mass rockets and finding the optimum mass.
â Why fixed drag coefficients matter for consistent results. Whether you're preparing for competition or just want to squeeze every last foot of altitude from your favorite design, this straightforward, science-based approach will improve your results immediately. Watch the Video Now â

https://www.apogeerockets.com/education/downloads/Newsletter200.pdf Bonus Video: How to power on your Blue Jay Plus Altimeter Because it doesn't use a traditional on/off switch, powering up the Blue Jay Plus atimeter is a little bit tricky. In this additional bonus video, we'll show you how to turn it on using the included magnet. We'll also show you how to orient your altimeter in the e-bay of your rocket.
The advantage of the magnetic activation is that you don't have to cut a hole in the side of your rocket in order to install or activate a traditional switch. This gives you a more aerodynamic rocket and also reduces the amount of work you have to do to set things up. P.S. Love this type of hands-on learning?

| Check out the latest products to hit Apogee's shelves! | Apogee Arc Stratus | | Our new Arc Stratus kit is out, and is perfect for intermediate level rocketeers and STEM enthusiasts. This two-stage powerhouse soars on twin 24mm motors, leveraging gap-staging tech to ignite its sustainer flawlessly mid-flight. Its rugged laser-cut basswood fins and through-the-wall mounting provide stable ascents and touchdown durability, while the 9-inch clear payload bay invites creativityâlaunch micro experiments, trackers, or symbolic mementos, all cradled in a sleek, BT-60 airframe. Inspired by the legacy of the Estes Loadstar, but refined with modern muscle, the Arc Stratus balances nostalgia with innovation. Also comes with Kevlar shock cord, spring steel engine clips which enable motor swaps in seconds, and chrome decals that scream "look at me." Whether youâre chasing altitude records, classroom wow-factor, or the thrill of mastering two-stage flight, the Arc Stratus doesnât just climbâit carves your name into the sky. Are you ready to challenge the laws of physics and launch your legacy? [Shop Now]. |
| RS-Pro Upgrade | | The lastest version of RS-Pro is now available (v4.2.3f2). This new version has several new features, including the ability to 'read in' recorded altimeter or GPS data from Featherweight devices. This will allow you to display the trajectory of your actual launch in the 3D Launch Visualizer in realtime. We call this "replaying the flight." You can also compare this trajectory against predicted simulations from RS-Pro so that you can determine what can make your sims or your flight better in the future. If you're already a RS-PRO user, this is a free upgrade, and you can do a "check for updates" from within the software and get it right away. |
| Apogee Invicta | | The Apogee Invicta is a high-power, two-stage marvel designed for thrill-seekers and skill-builders alike. Standing nearly 6 feet tall with a robust 3-inch diameter, this rocket combines laser-cut precision and electronic staging for jaw-dropping air-start flights that will have every video camera on the field pointed at your rocket's launch. Perfect for post-certification enthusiasts, the Invicta offers versatility: fly it as a towering two-stage beast (using motors up to "I" class) or solo with just the sleek upper stage. With rugged through-the-wall fin construction, reusable nylon parachutes, advanced features like removable rivets for easy access to electronics, and an innovative baffle system, itâs built for repeat adventures.

| | Launch of the Week! In this week's Advanced Construction Video (above), I showed a ultra lightweight carbon-fiber rocket that we use in competition, and how we found the optimum mass for it. In this launch simulation, you'll see that rocket fly. The launch site chosen for the simulation is the field in Aradac, Serbia where the World Spacemodeling Championships will be held in August. I wanted to get a lay of the land and see what obstacles we might encounter while chasing this streamer duration rocket for 3 minutes. What do you think will be the greatest obstacle for recovery? | |
| Customer Testimonial âJust a few words about my experience dealing with Apogee Rockets. 1) complete product line from kits to all you need to design your own and everything you will need to build and launch your built. 2) software to assist you with your designs and kits so that you can be assured of each launch being successful. Test those modifications on the computer before flying and enjoy the benefits of safety as well as improved results. 3) did I say very complete product line with multiple vendors. 4) wonderful and knowledgeable staff both online and in person who can answer detailed questions about your rocket needs. Problems about your center of pressure and center of gravity on your new design? Give them a call or better send them the plans. What motor to test with first? Just ask. If I seem over enthusiastic your correct. I deal with many hobby shops in both rockets and radio control planes and thru experience I can say that Apogee Rockets brings all of the above and much more to this...â -- Terry Breckenridge | |

| 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. | |
