Playz V8 Combustion Engine Model Kit That Runs - Build Your Own STEM Mini V8 Model Engine Kit for Adults & Kids Age 12+, Visible V8 Mini Engine Kit That Works for Adult w/ 270 STEM Parts

I bought the Playz V8 Combustion Engine Model Kit That Runs as a hands-on project, and overall it delivered on what it promised: a legit working model of a V8 engine with moving pistons and belts. Watching it run after you finish building it is genuinely satisfying. The good: • It actually runs. The pistons, crankshaft, and belt system move like a real engine, which is awesome for learning how everything connects. • Great STEM-style project. This is way more engaging than a normal model kit. • Fun to build with someone else. It’s a solid bonding project if you’re doing it with a kid, teen, or even another adult. The not-so-great: • The instructions could be clearer in a few steps. Some parts are tiny, and one mistake early on can cause issues later. • A couple of pieces felt a little flimsy. Nothing broke, but the plastic quality isn’t premium. • This is not a “quick build.” It takes patience and a steady hand. Bottom line: If you enjoy building things and don’t mind a bit of trial and error, this is a really fun and educational kit with a great payoff at the end. Just don’t expect it to feel like a high-end model or to be easy for younger kids without help. Would I buy it again? Yeah—just with the expectation that it’s more of a project than a toy.

Bought this for my son for Christmas. He enjoyed every part of it; from the level of difficulty to put together to the clear parts that allowed viewing the internal workings of a v8 engine. Had a small issue up arrival, but customer service went the extra mile to solve it quickly and beyond what was needed. The set itself gets 5 stars, would rate customer service 6 if I could. Highly recommend.

This is a good model if you take it for what it is. I learned a lot about how a V8 engine works. It took about six hours to build due to some mistakes. I learned about the 4 stroke cycle and could see it in action. I also learned about how the cam shaft rotates the pistons and why timing is so important in an engine. Thus, if you are only wanting to learn how a combustion engine works, without relation to a car, this is really good. As stated, I learned a lot. I will talk about the model build and then some weaknesses below. Building the model: The instructions give you the guidelines to build the engine. It took me about six hours to builkd including mistakes. Once in a while the instructions are vague which could lead to mistakes, or at least it did for me. But, the mistakes were good as I learned about the engine build from those mistakes. The parts fit together relatively easily. There are some parts requiring patience. The plastic parts sometimes need to be filed when removed from the plastic frames to make them fit correctly, but I am sure that is true of any plastic model. One plastic piece does have a thin tip and broke while removing it from the frame. I contacted customer service and they are replacing the piece, but I just continued without it as I didn't want to wait to finish the model. When finished the model is powered by batteries, instead of gasoline. The model does show the turning of the pistons and the timing of the spark plugs and valves extremely well. As another reviewer stated, it would be nice if there was a way to turn off the artificial engine noises. Overall, I learned a lot about an engine. Weaknesses: Well, it doesn't really show you how a V8 engine works in relation to a car. For instance, I have no idea how oil is circulated through the engine. I don't know how the radiator is involved in cooling. It doesn't have any indication as to how it might connect to a transmission. It also doesn't really show how the battery and alternator might work together with the engine. Now, what I will say is the model never claimed to do these things. But, if you are looking for those types of things, you might want to select a different model.

Fun to build and fun to teach and learn with! Simple to do!

Kids enjoyed it, dad restores cars, so this was a perfect homeschool project. We are missing a small part, but we emailed the company and are waiting to see if they can send it.

Cool model - but had to reach out to company for missing valve springs. Hopefully they will make this right. Wwas hopeful it contained more educational detail around how the engine worked instead of just a couple high level pages that were part of the assembly manual

Playz V8 Combustion Engine Model Excellent service and enjoyable learning experience – do not hesitate to buy! Purchased as a Christmas gift for my 11-year-old nephew. During assembling he noted that one of the connecting rods and connecting rod cap was missing and stopped building. His mom attempted to contact Playz but received no response – I suspect that she was using the QR code method or missed their reply, do not know. About month later I reached out to Playz support via their email and received a response from them within 24 hours. Within 72 hours of forwarding the details needed - Playz support had agreed to send on the missing parts and MUCH more! Playz support did ask for: • Amazon order ID or Website purchase ID • A clear photo of the missing part marked in the instruction manual (already sent) • Your full shipping address (if different from the one sent above) • The email address used for warranty registration We received FULL replacement kit in a couple of days. Please note Playz did state it would be 5-7 days but it was much quicker. Nephew re-started the build – he had to rework a few steps but that is part of the learning process. Once completed he took pictures and videos and shared with the family and his friends. Both he and I were proud of his work and patience. All and all, outstanding support and fun project!

Well my kit, fun to assemble. Highly Recommended!!!
