[Not displaying correctly? View web version.] | Peak-of-Flight Newsletter #587: | Ryan wrote me asking: “I am stuck on researching how to do a test of dual deployment on the ground. I have the Peregrine and after I do my L1 cert, I want to do dual deployment. I see people hook up a shop vac and I assume it is pressurizing the rocket to trick out the altimeter. How do I run a test on the ground to trigger the drogue chute and the main chute. Any videos on that?” Very good question Ryan. I’ll try to answer it here. There are two aspects to be concerned about when doing a dual-deployment. And that is why ground testing is important. These are...

Check out the latest products to hit Apogee's shelves! Lifting Eye Nuts | Looking to simplify your ebay set-up? Instead of using two threaded-rods, which most people do, you can cut down to just one by using these 1/4-20 Lifting Eye Nuts. They are perfect for securing your shock cord to your ebay and locking in your ebay sled's threaded rod. Using these multitaskers can replace standard eyebolts, reduce the weight of your rocket, and they don't require wrenches to install and remove. |
Estes A3-6T motors | We've been waiting for the Estes A3-6T motor to be re-issued for a long time. It is a long delay motor, that is great for upper stages of high performance rockets, like the Apogee Spek and the Midge. There is also a re-release of the Estes A3-2T motor, which is great for high drag models like gliders that don't coast very high and need a short delay. They are both in stock and ready to ship today. |
NCR LaunchMaster Controller | If you are looking for a more robust launch controller once you have graduated from A/B/C powered rockets, the NCR LaunchMaster™ should be your choice. It is bigger than the traditional starter set launch controller, and it uses batteries with larger electrical capacity so you can launch lots of rockets in succession without having to worry about having enough power. And it contains 30 feet of wire, giving you safety to launch motors larger than a D-engine. |
NCR Blade Caddy | The North Coast Blade Caddy™ is a safer way to store your razor blades. With four convenient slots, your razor baldes will be secure and non-hazardous when you set them down to continue to the next step in your build. This handy holder is 3D printed in a variety of brightly colored ABS plastic fillament so you won't lose it on a cluttered work top. |
Gliding Parachute System | Gliding parachutes have the advantage that they can be steared. That means you can bring them back to yourself instead of having them just drift in the wind. Additionally, they are more efficient that a round parachute, so a smaller chute will give you a slower descent rate. This is an experimental system that includes a nylon cloth Rogallo-shaped parachute and the controller ebay. It also comes with a servo, battery, and a charger for the battery. You will need to provide your own model-airplane style RC receiver and transmitter and have experience using them. Three sizes are available: 24", 28" and 32".

| What's Wrong With This Launch? There is something definately wrong with this week's simulation. What would you do differently with this flight to make it OK? The purpose of the Launch Visualizer is to make sure that these situations don't happen, by running the launches virtually before you get on the field. In fact, since everything is online, you can run these simulations with actual wind conditions right there at the launch site. Isn't that worth it? |
“I was able to meet Tim the owner on a work trip to Colorado. He was one of the nicest and most knowledgeable people I have met. He gave me a tour of the facility and brought me out to the Southern Colorado Rocketry club launch. He was able to answer every question I had no problem. Any time I have questions I email them and within hours I have a response. I love Apogee Rockets.” -- Dustin Taylor | |
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. | |
