An ideal introduction to rocket building, this set contains two rocket kits: the Amazon and the Crossfire ISX. It also comes with a launch pad for easy launching, plus two plastic parachutes that ensure a gentle descent to the ground. Whether you're a new rocketeer or a seasoned veteran of the skies, the Tandem-X is sure to deliver plenty of high-altitude thrills. Learn the basics of crafting model rockets with the 3-foot tall Amazon and 15 inch Crossfire. View larger. Its launch system includes a stabilizing launch pad and push-button controller. View larger. Blast Off to Extreme HeightsWith two rocket kits, the Tandem-X Launch Set offers two unique launching experiences. The aptly-named Amazon is the bigger of the two rockets: it towers at almost three feet tall and features a fearsome tiger-stripe decal. When flown with a standard Estes engine, the Amazon can soar to heights of 600 feet. The Crossfire is a smaller craft, standing just a little over 15 inches tall. In spite of its size, this little rocket can blast off to seriously impressive altitudes. Thanks to its aerodynamic fins and nose cone, the Crossfire can reach cloud-bursting heights of 1,150 feet. Both rockets are outfitted with colorful, preassembled parachutes, which ensure they can float gently back to Earth for another flight. An Introduction to Rocket BuildingThe Tandem-X Launch offers just the right amount of challenge for novice rocket builders. The Amazon is an E2X (easy-to-assemble) rocket, and requires no paint or special tools for assembly. It can be built in less than an hour: simply glue the plastic fins to the tube, install the engine, and attach the parachute. Finish the rocket off with a few self-stick decals, and you're ready to launch. Once builders have mastered the basics, they can move on to the more advanced Skill Level 1 Crossfire. With its plastic nose cone and laser-cut balsa fins, the Crossfire requires a little more finesse. Assembling the rocket can take an entire afternoon, but it's a rewarding and educational process. Builders will learn several beginner-level rocket techniques, such as painting and sanding. Estes has also included an illustrated, step-by-step instruction guide to help keep the assembly fun, smooth, and frustration-free. Educational FunIn addition to the thrills it provides, the Tandem-X also has significant educational value. The set transforms kids into amateur rocket scientists, encouraging them to think about how the rockets work. Rocket building teaches kids the basics of propulsion, flight, and aerodynamics, and can help foster an early interest in science and engineering. Even failed launches can turn into a learning experience. Requires an Estes EngineBoth rockets require a specialized Estes engine to launch. For the Amazon, Estes recommends a B4-2 engine for your first flight. The rocket is also compatible with other Estes engines, including the B4-4, B6-2, B6-4, C6-3, and C6-5. For the Crossfire, Estes recommends the A8-3 for first flight, and the B4-4, B6-4, C6-5, and C6-7 for more advanced launching. What's in the BoxEstes 1469 Tandem-X Launch Set with Amazon rocket kit, Crossfire ISX rocket kit, two plastic parachutes, launch pad, and push-button launch controller. P.when('A').execute(function(A) { A.on('a:expander:toggle_description:toggle:collapse', function(data) { window.scroll(0, data.expander.$expander[0].offsetTop-100); }); }); From the Manufacturer Two is better than one. You’ll get X-tra value with the Estes Tandem-X Model Rocket Launch Set. This exceptional rocket set features a pair of extreme, high performance rockets with a launch system for launching them. Whether you’re a new rocketeer or a seasoned veteran, launch in tandem for an exciting model rocket experience. The E2X (Easy to Assemble) Amazon is as imposing as the name sounds. This giant towers almost 3 ' (91 cm) high and is quick and easy to build. A tiger-striped body tube, precolored plastic nose cone and fins and self-stick decals make building this rocket easy to do in about an hour. When flown on our standard engines, this huge rocket can reach heights over 650 ' (198 m) with recovery on a colorful 18 " (46 cm) preassembled parachute. The Crossfire ISX is a Skill Level 1 kit that can easily be built in about a day. This rocket features a totally streamlined shape with aerodynamic fins and nose cone. It stands 15.6 " (39.6 cm) tall. When launched with powerful Estes standard engines, this bullet can reach cloud busting heights up to 1,200 ' (366 m). A preassembled 12 " (30 cm) parachute returns the Crossfire back to earth to launch again and again. Glue, modeling tools and Estes engines required - sold separately. The Electron Beam Launch Controller uses 4 AA 1.5V batteries - sold separately. Recommended for ages 10 and up with adult supervision for those under 12. See more

My favorite Melatonin supplement
Size: 100 Count (Pack of 1), Style: Melatonin 1mg
I have used this for a few months and really like it. I had previously used a spray that for some reason had added B6 (>2000% RDA) and I developed toxic levels of Vitamin B6 so had to switch. I love that this doesn't have any added garbage including no added flavors, artificial sweeteners or artificial dyes. The taste is fine. It's not candy and isn't supposed to taste like candy. It is just a bland taste that I hardly notice. Dissolves quickly and easily. Love it.

TLDR: Don't wait! Buy it now! This stuff is really great and I think you're gonna love it!
Size: 90 Count (Pack of 1)
Life Extension Neuro-mag: I first learned about magnesium l-threonate on YouTube. It was recommended by several physicians there and in person, all of whom consistently make good suggestions in terms of health optimization. Even still, I didn't go for it right away, unsure if this form of magnesium could really be much different than or better than the liquid magnesium from Life Extension that I've been using with great results for several years now. Still, I was curious, as I did some more research and I kept hearing and reading that magnesium l-threonate is “different” because it crosses the blood-brain barrier. Now I'm not gonna try to explain in detail what that is, but I had an understanding of it enough that hearing this further intrigued me. It's my understanding that the human body has this protective measure in place to protect us and for very good reasons so I wanted to be sure I'm making a safe decision for me. As an overview, basically you want the good stuff you consume, that your brain needs to function, to be able to make it to your brain- but not everything. I don't know how our bodies work this out, but apparently they do, so we don't have to figure it out on our own. Imagine that, trying to tell your gut where to send each calorie and nutrient etc.? Anyway, I decided to give this stuff a chance and within 3 days I knew that I will never go without this form of magnesium again if I can help it. For me, it's really that amazing, and of course as a consumer, I hesitate to say, but it's absolutely worth the asking price and more. I've had years of experience with this brand now too and it's been top notch from the packaging to the product, so I will keep buying from Life Extension. With this I sleep better, problem solving is less stressful and my energy level has improved. It does have the relaxing effect on my body that other forms of magnesium do too, but this one has such a profound effect on my mind it's very difficult to quantify, or put into words in text that can even begin to convey or actually help you comprehend just how powerful the effects are. Kind of like the old saying “you had to be there” I suppose. That said, eventually I did buy the magnesium l-threonate from Life Extension and it is quite literally one of the best decisions I've EVER made in my nearly 50 years. It's weird to say that, am I really that old? Seriously, if you do some research and find that the effects sound like the type you might benefit from- buy it!

Great Product
Size: 90 Count (Pack of 1)
Life Extension’s Neuro-Mag Magnesium L-Threonate is a standout supplement designed to support cognitive health, and after trying it for several months, I can see why it’s so highly regarded. This product contains magnesium L-threonate, a unique form of magnesium that’s specifically formulated to cross the blood-brain barrier, making it highly effective for brain health. Each serving (three vegetarian capsules or one scoop of the tropical punch powder) delivers 2,000 mg of magnesium L-threonate, providing 144 mg of elemental magnesium. Here’s my take on its performance, benefits, and overall experience. Pros: • Cognitive Support: I noticed improved mental clarity and focus after about two weeks of consistent use. Tasks that require working memory, like recalling details or multitasking, felt smoother and less taxing. This aligns with research indicating magnesium L-threonate’s ability to enhance synaptic density and cognitive function, particularly in aging individuals. • Sleep Benefits: While not marketed primarily for sleep, I found that taking it about an hour before bed helped me fall asleep faster and wake up feeling refreshed. This echoes user experiences shared on platforms like X, where some reported better sleep quality and daytime alertness. • High Absorption: Unlike other magnesium forms like oxide or citrate, which are better for whole-body benefits, magnesium L-threonate is designed for brain absorption. Studies cited by Life Extension show it can boost magnesium levels in cerebrospinal fluid by 15% in animal models, which likely contributes to its cognitive effects. • Clean Formula: The capsules are gluten-free, non-GMO, and vegetarian, with no major allergens or unnecessary fillers. The powder version has a pleasant tropical punch flavor, making it easy to mix with water or juice. • Trusted Brand: Life Extension’s rigorous testing for purity and potency gives confidence in the product’s quality. Their transparency, including offering Certificates of Analysis, is reassuring. Cons: • Price Point: Neuro-Mag is pricier than standard magnesium supplements, which might be a drawback for budget-conscious buyers. However, the specialized form and targeted benefits justify the cost for those prioritizing brain health. • Time to Notice Effects: While some users report benefits in as little as six weeks, full effects may take up to 12 weeks, requiring patience. Final Verdict: Life Extension’s Neuro-Mag Magnesium L-Threonate is a high-quality supplement that delivers on its promise of supporting cognitive health. Its ability to enhance memory, focus, and even sleep quality makes it a worthwhile investment for those prioritizing brain function. Great benefits and clean formulation make it a top choice!
