  • Fun, detailed, and educational (but not perfect)
Overall, we loved this very well engineered model. We did run into a few problems though. First, the crankshaft was sloppily molded in one section where 2 of the piston connecting rods are supposed to attach (step 2). It’s supposed to be a circle but, since each each half was slightly offset, it ending up being a bit too wide. Also (and for the same reason), it had ridges that preventing smooth rotation of the connecting rod around the crankshaft (see photo). I was able to sand it down with a small file to get it to work. Second, there were 3 instances where screw holes had to be created or widened. If there was no hole, I very carefully started a hole (really just a mark in the plastic) with a small nail then used a small wood screw to widen it. I was worried that the plastic would fracture but it didn’t. I was very gentle. Third, the left distributor (for cylinders 5-8) was quite difficult to place onto the camshaft (step 26). The camshaft is not perfectly circular but deliberately has one side that’s flat as does the hole in the distributor. They were not easy to match but a lot of jiggling and persistence finally won the day. Fourth, during the timing step (step 27), the distributors have to be turned clockwise in order to illuminate the correct “spark plug” (LED light) but even when the right-handed distributor (for cylinders (1-4) was turned as far rightward as the screw slot allowed, it still didn’t light up the correct LED. It turns out that the screw slots had to be turned just a hair past the screw posts in order to light up the correct LED (#4) but that would mean the distributor couldn’t be screwed in place (it’ll make sense when you get to that step). To fix this, I widened the left side of the screw slot with a small file so it could turn just a wee bit more to the right. That was just enough to work. Another fix is to swap the right and left distributors (see the excellent review by Jerry Davis) but I didn’t want to remove them as I had trouble getting the left one on in the first place. Finally, it should be noted that newer version of the model has 2 additional plastic posts on the front of cylinder block on either side of the crankshaft (at about 4 and 8 o’clock) to help keep the timing belt from falling off. I only mention it because it was a little confusing that our cylinder block didn’t quite match the diagram in the manual. A few tips: I was worried that my smaller than average 8 year old daughter wouldn’t be able to screw in the pieces since several reviewers said it was difficult. However, she didn’t have too many problems in that regard. It comes with a a very small Phillips head screwdriver that worked fine. Ours didn’t come magnetized but that’s ok. Some people prefer it that way. We did, however, magnetize the screwdriver with a magnet which I think helped. We also used an accessory screwdriver with a wider handle (whenever we could) to make it easier to turn. We also purchased a cheap modelers tool kit (Rustark 10Pcs Model Tools Craft Set Modeler Building Kit) for about $10 that came in handy, especially the file, the small knife, and the side cutter (for cutting the pieces away from the plastic frame). Just be patient, read the directions very carefully, read some tips in the amazon reviews (Jerry Davis, A. Aurelius, etc) and be prepared to modify a few pieces. Summary: The educational value is through the roof and it was a ton of fun to build. I have almost no model building, automotive, or mechanical skills to speak of but we were still able to get it done in a few hours spread out over 3 days with the timing spot on. It’s extremely detailed and teaches not just how an internal combustion engine works but about a lot of other principles of mechanical engineering like cams, gears, pistons, bearings and other stuff I can’t think of because I don’t know jack about engineering. It also teaches patience, troubleshooting, and persistence. The kit says for ages 14+ but I would guess that an interested 11-12 year old should be able to do it with minimal help. One reviewer says that her 9 year old finished it unassisted but I find that surprising (so did she to be fair). I think most 9 year olds would need at least some help. But that’s part of the fun. I LOVED building it with my daughter (who has expressed an interest in engineering). Almost forgot to mention that this latest version comes with an AR (augmented reality) feature. It’s super cool and educational. Didn’t work on my iPhone X but worked perfectly on our iPad. I would highly recommend this model for kids, teens, and adults who are interested in learning how an internal combustion engine works. My daughter enthusiastically rated it 5 stars but I’m thinking 4.5 just because I had to modify some components to get it to work. Hope this helps and have fun!! ... show more

  • got product with defect (but seller fixed it very fast)
when I just started unpacking, I noticed on one part a muddy badly thrown out corner, and on the second same part, I noticed a mismatch compared to the analog. But due to the fact that in the place where the was missed part of this detail, it looked like a clean, smooth edge, as if it was intended that way. The thought was maybe it was necessary to take a room for the location of another part, and so on. but I had not yet seen all the nuances of this defect on that moment. Of course, I took all the photos during unpacking, just in case ... During assembly, I already realized that this was a defective part that it was hard to close my eyes to, since this is not only the absence of some kind of plastic walls. What melted this part with something (or simply did not finish it) and melted not only the outer and inner horizontal wall, it also melted half of the mount rod into which suppose to be screwed bolt and keep together thus detail with the upper detail. This defect also melted (its doesn'texist ) bottom mount support whith should hold the camshaft axis. Well, as I understand it, the manufacturer doesnot have quality control at all. I would not want return it, since I’ve already assembled of half of it, but I’ll probably have to, because this is a significant drawback. If the seller provides me with this part, then I will keep it and let you know (will update here) whether a quick replacement of the part is possible so as not to make a return... update: as promised So, seller very good 👍 lightning fast responded and without any questions asked for my address for confirmation. And then with lighting fast speed sent me replacement to me and even I do not need send my existing kit back to them (I will get it during 2 days). So, I recommended buy from this seller and ofcause recommend to buy this engine kit because it's really interesting and good designed product. Easy to assemble. Even it's for kids 12-16 (I am much older) I got enjoying to assemble it (its going be part of my project) ... show more

  • Awesome project build
Pretty well engineered model. But some of the holes for the screws did not match up well making this project a little challenging. The color scheme was a little boring so I spruced it up with some water based paints. Here's how I did the color scheme: Screwheads black against chrome; red otherwise; black against red head gaskets; pistons, crankshaft, rocker arms gold; oil pan, bell housing, intake plenum, fan jewel green; sparkplug wires yellow; lights "sparkplugs" white; and red highlighting. Metallic water-based paints work well with projects like this. I used the paints as is or thinned a little with water. If the paint is thinned too much it will not adhere well to the plastic parts. Fun project! ... show more
