| [Not displaying correctly? View web version.] | Peak of Flight Newsletter #512: | |  This week David Flanagan walks you through guide chutes for smaller parachutes as part of a dual deployment system.
Guide chutes are small, very stable, non-gliding, low drag parachutes. They support dual deployment when a parachute release mechanism is used. A guide chute is ejected from the rocket at apogee along with the rest of the recovery system and opens immediately. Used properly, it keeps the main parachute (contained in a parachute release) in “clean air” above all other components so the main chute can deploy without fouling. The high speed descent (sometimes called “droguefall”) that occurs before main chute deployment limits the distance the rocket will drift during recovery. | | 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! | Experimental Composite Propellant Cookbook | | 
Looking to make your own rocket motors? This guidebook is a great place to start. Experimental Composite Propellant by Professor Terry McCreary PhD. details the formulas, safety precautions, design, construction and testing of small rocket motors. This isn't for everyone. We recommend it for those people in countries where we can't ship rocket motors. |
| 1/4-20 X 9" long Threaded Rod | | 
This is the threaded-rod (sometimes called "all-thread" stud) that we use for our own 98mm e-bay kit. Now you can make your own electronic-bays for your fiberglass rockets or your own home-made scratch-built designs. Use standard 1/4"-20 nuts available from your local hardware store. |
| AeroTech Arreauxbee-Hi | | 
The AeroTech Arreauxbee-Hi is a great initiation into larger mid-power rockets. It is a straightforward assembly, with a clean orange and metallic asthetic. The rocket can house a variety of rocket motors and flies with great stability. |
| 54mm Fly-Away Rail Guide | | 
The 54mm Fly-Away Rail Guide can be used to launch those 54mm diameter rockets that do not have a rail button or rail guide. The advantage of removing the rail buttons is that it reduces the drag of the rocket and allows it to soar higher. Package contains one set of rail guides that will fit on a 54mm (thick-wall tube) rocket. |

“I have found out that Apogee is by far the most beneficial company for my rocketeering needs. The components, kits, service, and quality are second to none. I appreciate everything they provide, especially the service and technical knowledge they provide. I would highly recommend anyone, from novice to cert 3 individuals. Thank you for everything you do for the hobby.” — Barry Depczynski | |

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 upto $350 for your time. | |

 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. 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. | |
