    • A fun / cheap project for kids
I built this with my 8 year old son and it worked as expected. The instructions however were in pretty broken English and included warnings that it is easy to completely destroy the project by not following them precisely. Luckily we had no issues and were able to complete the project in an hour or so. ... show more

    • Not for beginners
This kit was very rewarding to build. And super easy to follow the instructions, but as it says all over the product, you really need to know how it works to trouble shoot. Mine went together fine, runs great, but had a lot of issues keeping the flame on the bulb regardless of wick height, and the crank/conrods were a little crooked and wobbly. This caused the rods to rub the flywheel (super small tolerance difference nothing crazy) so I had to adjust the spacing, and ended up finding a little burr on the casting where the bearing inserts. The point of noting that, is an engine of any type is a precise machines device, and a beginner may not find little things that cause innefiencies. After a little bit of oil she runs silently, and almost starts on her own. Just a little nudge. Beofre I adjusted things she was noisy and needed a sharp spin to take off. ... show more

    • Works
Worked as should. Some parts are really small so I had to use cheaters lol

    • a marvelous model
This is a marvelous model. The castings and machining are impressive. Here is what I found in assembling it. 1. It needed gentle filing to remove a bit of casting from the outside of the hole so the bearing for the flywheel shaft fit. 2. putting the retaining ring on double stick tape affixed to a popsicle stick made pushing it on the shaft go well. 3. oiled the moving parts as they were assembled. 4. The small end of the pipette provided can be heated gently in a small flame and pulled out to give a small enough diameter to fill the alcohol tank through the vent hole. Very enjoyable, went too quickly. ... show more

    • Somewhat picky but quite fun
The kit was a cakewalk (I dont actually know what that means) to assemble. Though I have had to take it apart and put it back together a few times it is very easy to do so. Take time with it and pay close attention to the pieces and remove any burrs, the tiny keepers are super easy to lose so put it together on top of a big table or something of the like. Make sure you grab some tweezers to make your job easier. Though at first it ran on low grade rubbing alcohol (lazily) you will for sure want to find the strongest stuff you can 99% works great. The issue is with the wick placement, in theory it's where it should be but if there is a draft or its winter on the palouse then you can expect issues. With high grade alcohol I had no trouble when the room temp was 62, with low grade i could feel it build compression but it would not run. All in all this is a neat kit and it taught me more than reading forums ever did, take it easy and have fun learning, be patient and you will enjoy it. ... show more

    • Easy to assemble.
Just finished assembling this. It takes about 30 minutes. Some very small parts so keep your work area clean. It ran the first time with no issues. This kit is very well machined and well worth it. I particularly like the built in reservoir for the alcohol and all metal cylinders as opposed to glass ones. ... show more

    • Not for the beginner.
I am an engineer with fine tools used in many of my projects. If I did not have these tools and many years' of experience in engineering, I could not assemble this engine. The engine worked fine after I assembled it. Not for children or the beginner.

    • Very Fun, and a nice Introduction to the hobby.
Arrived in one piece, no missing pieces. The main shaft was machined poorly, BUT I managed to make it work regardless so no harm done. I just picked up this hobby and this was a very fun way to break the ice. One thing the instructions won't tell you is that the spacers are paper thin, I recommend using the 2 spare spacers and put 2 on each side of your flywheel. Also, put a couple of drops of lubricant where metal rubs on metal and it will reduce heat and friction, thus making it faster and even more fun. Hope this helps. ... show more
