Check out the latest products to hit Apogee's shelves! Zephyr Bulk-Pack | Here is a 5-pack of the Zephyr rockets, perfect for school groups. This is a great rocket to use for Level-1 high power certification because it is big and robust. It flies low and slow, which helps recovery after the flight, but can still easily take the punishment of high thrust motors. It is simple and easy to build thanks to its highly illustrated instructions. And it uses fool-proof motor ejection, so no electronics are needed. Save money by buying in bulk! |
G-Flex Thickened Epoxy | G/flex 655 Thickened Epoxy quickly builds up thickness and will not run or sag, making it great for fillets on your rocket. It permanently bonds fiberglass, ceramics, metals and plastics. It adheres tenaciously to difficult-to-bond woods including resinous woods and even wet wood. It is also toughened (with rubber addatives) to make structural bonds that absorb the stresses of expansion, contraction, shock and vibration. Check it out here. |

| Customer Testimonial “Our school is participating for the first time in American Rocketry Challenge. Our students researched where to get the necessary components for their design and suggested we use Apogee for a lot of the components. Apogee not only had everything we needed but their prices were reasonable and the service was excellent. Based on our buying experience, our rocketry team feels comfortable recommending them to other teams.” -- Dan Cipolla | |

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. | |
