[ Not displaying correctly? View web version. ] | Apogee Rocketry Workshop #372: | The new Experimental Gliding Parachute could be a game-changer when it comes to mid and high power rocketry. Instead of the rocket drifting downwind on launch, the parachute can be steered into the wind, and can be brought right to your feet via RC control. You won't have to spend time retrieving your rocket, it will come back to you. We call this: Come To Me Recovery™ Because this parachute is radically different from a traditional chute, and requires a bit of set-up, we've made a series of videos that walk you through the assembly and preparation steps. This fourth video shows how to cut the Kevlar support lines and attach them to the electronics bay. Two of the lines will be fixed, and they support the mass of the rocket. The other two are the steering lines, and they will be used to pull on the tip edge of the parachute in order to change the direction that the chute is flying in. View this week's Rocketry Workshop Videos (Duration 13 min, 17 sec) If you would like to see the gliding parachute in action, start your journey here. | Previous videos are found on our archive page. |
Check out the latest products to hit Apogee's shelves! Quest E35 Single-Use Motors | The Quest E35W might become one of your favorite mid-power rocket motors that are 24mm in diameter. This is a FULL E-motor, being at the upper limit of just under 40 N-s of total power. It has great kick off the launch pad, which is what is needed for heavier rockets or those that are larger in diameter. At 95mm (3.75 inches) long, it is the same size as the Estes E12, but with more power, a huge white flame, and a deep throaty roar. And it still won't go so high that you'll risk losing your rocket. It comes in delays of 5, 8 and 11 seconds. It will be great in the Katana Jr, the LexxJet and the Super Big Bertha rockets (29mm adapter not included). |
Aerotech I40N-P Motor | Aerotech continues to expand its line of single-use high-power motors. The latest DMS motor is the I40N-P motor. This is a long burn motor, with a thrust duration of 10 seconds. It utilizes the Warp-9 propellant in end-burn fashion to give this really long burn time which can allow extremely high altitudes for your lightweight rocket. But beware, it is plugged and therefore does not contain an ejection charge. So you'll need to use a dual deployment altimeter to kick out the parachute to bring your rocket safely to the ground. |
Estes Super Big Bertha | The Estes Super Big Bertha is a mid-power rocket using 29mm diameter motors, that is over 3-feet tall and 2.6-inches in diameter. In this upscale of Vern Estes' design, the charm of his original Big Bertha model has not been lost, nor has the low-and-slow flight capabilities. This rocket could be flown all day on Estes E16s and recovered without breaking a sweat. But if you were in the mood for something more, it would fly nicely on any 29mm F motor around. |
Katana Jr Dual Deployment - at a Mid-Power Price | Do you want to try out dual deployment, but don't want to build a high power rocket that requires either certification or expensive rocket motors? The Katana Jr. is our "practice rocket" for this very purpose. It is a FULL dual-deployment rocket, with a ebay, two parachutes, removable rivets, mounting hardware for the electronics, and a on/off switch. Plus, it has easy-to-follow instructions that will walk you through the process of doing dual deployment if you've never done it before. It is a 1/2-scale version of our popular Katana rocket, which means this rocket will slice the air just like its big brother. |
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. |
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".

| LexxJet Zooms Skyward The LexxJet is a rocket that I seem to launch often. It doesn't look like a traditional rocket at all, but it sure does fly straight. It always surprises spectators at how beautifully it flies. This week's simulated launch (click here) is the LexxJet from the club site of Mantua Township Missile Agency outside of Cleveland and Akron, Ohio. It sure looks like a beautiful day to fly rockets. What do you think? |
“Recently my dad and I have started to getting back into building and launching rockets together. We are just now getting to a scale where we are talking about getting our level 1 certifications and continuing to build bigger and better from there. Apogee has been a tremendous help in both getting all of the parts that I need for the couple of projects we are working on and providing the information necessary for building things so that we don't have any unplanned rapid disassembly incidents. Shipping was fast, affordable, and everything I ordered arrived in the condition I expected. I look forward to continuing to work with Apogee to source everything that I need to continue to build larger and more complex projects with my dad. They have made it so easy to reignite my inspiration for this awesome hobby!!” -- Christian Haakmeester | |

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. | |
