Playz V8 Combustion Engine Model Kit - Build Your Own STEM Mini Engine for Adults & Kids Age 12+, Visible Working Model With 270 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.

My 13-year old son really enjoyed assembling and watching this engine roar once it was completed! I highly recommend this product for children which like to assemble and operate machinery!

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.

So much fun to do. Took about 3 hours straight to complete but 9 year old and 41 yr old got it together, great project.

It is not often I take time out of my busy schedule to leave a product review, but I was so overwhelmed by the exceptional way this seller, PLAYZ, handled an annoying situation, that I had to. My husband ordered the V8 Combustion Engine Model Kit to put together with our 8 year old grandson. We own a car repair shop so it was an especially exciting idea, so he could "fix car engines just like Grampa does". They got more than 1/2 of the way into it & there was a broken piece in one of the sealed plastic bags. I emailed the company & they got back to me immediately, requesting a little more information. The very next day their very sweet customer service rep, Rachel, emailed me they have already sent us an entire brand new kit, at no charge to us. I was overwhelmed. I had expected I would have to jump through flaming hoops to even have the one small part sent, & that they would at least charge me shipping. But they went waaaay over & above, and I was especially impressed with the kind personal emails from Rachel besides the fact that they were sending a whole kit at no expense to us. Now maybe my husband & grandson can invent a new engine with all the extra parts we got for FREE!!!!! I always wondered if these kind of comments that companies post are real, but you can be sure this one certainly is!!! PLAYZ IS THE BEST!!!!!
