[ Not displaying correctly? View web version. ] | Apogee Rocketry Workshop #361: | Customers sometimes ask about the best way to fold a plastic parachute. The answer is that it depends on the weight of your rocket, the parachute size, and how durable you think it is. In this video, I'll show you two methods that I use when prepping my own rockets for flight. One way will allow the parachute to open really fast, but it puts a bit of extra stress on the shroud line attachment points. I use this technique for lightweight rockets, or if I know the parachute is a bit stronger and more durable. The other way of prepping the parachute allows it to unfurl a little bit slower, which gives the rocket time to reduce speed so that there is less of a snap on the suspension lines. I use it for heavier rockets, or when I'm concerned that the parachute might not be as strong as I'd like. Do you have a different method? Let us know in the video comments.

Check out the latest products to hit Apogee's shelves! Tip Sanding Burrs | Ever tried to sand into a tight corner and found the sandpaper won't conform? That's where these special metal files, technically called "Sanding Burrs" come in. We commissioned a special set of five diamond coated files that allow you to sand with the tip of the tool, so you can get into hard-to-reach areas. They can be used by hand, or with a rotary tool like a Dremel. The fine grit of the tools allow you to get that smooth surface even in the tightest corners of your rocket. Perfect finishes are now more easily achieved than ever before. |
T2 Tether and Release Device | From Tinder Rocketry, the T2 is a tether-release mechanism for high-power rockets. It allows dual-deployment to occur out of a single parachute bay by preventing the main parachute from deploying out of a deployment bag until a preset altitude. It replaces the old Tender Descender. |
Piranha Line Cutters | The stainless steel Piranha Cable Cutter is used to delay the opening of your main parachute, so it acts as a streamer initially, and delays the time at which the parachute opens. This prevents the rocket from drifting as far because the main parachute opens at a lower altitude. |
Chisel Tip Knife Blades | One of the lesser-known, but really practical tools for hobbyists, is the Chisel Tip Blade for a hobby knife. It can do things that you can't do with a regular #11 blade hobby knife nor a razor blade. What makes it really useful is that you can mount it in the handle of an ordinary hobby knife. That gives you a way of holding it that you can't get with other wide blades like a razor blade. Because it is in a handle, you can get it into hard-to-reach spaces that you can't normally access easily. | Make Carbon Fiber Tubes | Here is an extensive and detailed video course on how to make Ultra-Lightweight Carbon-Fiber Rocket Tubes. They're so light, they give you an unfair advantage in competition. These are the ones that my daughters, Allison and Ashley used in Romania last September at the 2021 World SpaceModeling Championships. Allison was part of the senior Silver Medal winning USA team, and Ashley took home the Bronze Medal in the Jr. Division. The girls were taught how to make their own tubes, so if they can do it, so can you. The training course consists of 5 hours and 42 minutes of video instruction, covering everything I know about how to make a successful tube with a glass-finish using a 2-piece mold. It even includes all the secret techniques and materials, and where to buy them, including where to get the 2-part mold. This course is on the Udemy website, not at Apogee Components. |

| Unstable After Apogee This week's free simulation shows a rocket that goes unstable after it reaches apogee. Hopefully you'll never see something like this at your launches. But it can happen. Why do you think the rocket goes unstable on this motor? What would you do to correct the issue so it doesn't happen on your launch? |

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. | |
