Estes Tandem-X Launch Set (Amazon and Crossfire ISX) Orange, 30 inches

Rocket launch setup takes 15 minutes from when you open the box, very easy. Don't forget to separatly buy recovery wadding paper, engines and batteries. Two small complaints: the parachute tore easily on first launch (bring scotch tape) and the rubber band detached from the inside of the rocket on the 2nd launch (bring duct tape). However, the rocket survived the 500+ ft drop to grass without a parachute. It goes very high with B engines.

Awesome, awesome. Was a quarantine project for my 9 year old and it delivered. He needed help putting it together and we had to watch a you tube video or two to figure out how to set it up for launch but the end result was worth it.Cons: the engines that propel it are sold separate and I had to order them from another vendor. Also you need some craft supplies for assembling which I did not have. Actually just used some construction adhesive on a popsicle stick which worked fine.Both rockets launched great. Parachutes came out and we re-launched them multiple times. The big rocket did catch some wind and sailed easily a 1000 yards away on us. So you need a big treeless area. The little one not as bad. Football field is big enough.

Me hubiera gustado que incluyera 2 engines para lanzar los 2 cohetes

Part of the reason I give this product 5 stars is nostalgia. As a kid I built and flew model rockets just like these. But I couldn’t afford the cool launch pad and rod, so I used a block of wood and a coat-hanger that I had laboriously straightened. Worked great, and tons of fun!The other part of the 5 star review is heart strings. These many years later when, my 8 yo son sat on Santa’s lap, the rotund old elf asked him what one present he would like to get from Santa. My son looked a little nonplussed to have to come up with ONE thing, but he gamely said, “I’d like a model rocket, just like my dad had when he was a kid.” Seriously? There was zero chance he wasn’t getting this for Christmas!A few folks have given this set less than stellar reviews, mostly based on misunderstanding what they were getting. Model rockets are not toys and they are not preassembled. Model rockets are actual functional rockets. They require basic model building skills (measuring, cutting, gluing, and painting), and they require engines to launch. This is not a negative, part of the joy of this hobby comes with the building.Here is a list of basic items you’ll need in addition to this kit to build and fly your rockets:1) Good quality white glue2) Plastic cement (the stinky kind) Cement Glue Value Pack Testors 2-7/8 fl oz tubes3) Paint. Spray paint works well for solid colors, but enamel paint is great for detailing Testors Promotional Enamel Paint Set4) Brushes Testors Nylon Paint Brush, Set of 35) Masking tape6) Fine sand paper7) Razor knife8) 4 AA batteries9) Fire resistant wadding Estes 2274 Recovery Wadding10) 2 sets of enginesAs model rockets go, these are actually very easy to assemble. Fins are usually the hardest part because you really have to be perfect in their alignment, but not on these rockets. The larger “Amazon” rocket has an injection molded fin assembly that just needs to be glued into the body tube. The smaller “Crossfire” rocket has balsa wood fins (*sniff* just like the old days), except these have been laser pre-cut for you. Even the body tube is pre-cut to accept the fins. Hard to go wrong.Quick primer on engines. They mostly come in 3-packs. Each engine is single use, then dispose of. They are real rocket engines and they burn pre-loaded solid fuel. The designation (example C6-5) tells you everything you need to know about the engine thrust profile. “B” engines are twice as powerful as “A” engines, and are half as powerful as “C” engines. The first number gives the average thrust (bigger is faster), and second number gives the delay in seconds before the ejection charge pops the chute. Engines come with the required igniters, but not the wadding.The flame resistant wadding protects the plastic chute from the heat of the ejection charge. Forget the wadding and your chute may melt, or even burn; not a useful recovery strategy! In a pinch you can get away with just using a regular tissue; it might smoke a bit as it falls, but will extinguish before reaching the ground. As a responsible adult trying to set a good example for my child, I bought the flame resistant stuff.I used B4-2 engines in the Crossfire rocket, and C6-7 engines in the Amazon rocket. The B4-2s were perfect, but the C6-7s have too long a delay and gave us a heart attack as the Amazon rocket turned over and looked like it planned to become a lawn-dart - before the chute eventually deployed! C6-5s would be a better choice here.My son loved launching these rockets! He was ecstatic when he almost caught the Crossfire rocket in mid-air as it was returning to earth. A video of his very first launch is attached. This little father/son rocket set is most highly recommended.Edit: I changed my title to make it clear that this is NOT a boy's toy, it is not scary, and it is not rough and tough. Any kid with an interest in engineering, or science, or just going fast and high, would probably love this product.Edit2: Youtube video of my son showing his mom how to use the launch controller and launch her very first rocket. Very exciting for the whole family!https://youtu.be/YOO3cI2NWvM

Its a good kit, but most people don't understand you need extra materials to launch it.
