Very satisfied. Delivery was quick, Instructions were easy to read and follow. First run identified some steam leaks, (my fault – just a little more tightening on the steam feed and pressure gauge). Everything was as advertised. Very happy with the finished item.
Quick stats…
• Built time: 6 hours.
• Run time on 70% water: Greater than 30 minutes.
• Run RPM: Slow with an occasional speed up in both forward and reverse.
• Noise: Minimal.
• Mess: Just a little cleanup needed after each run.

I received my 100th anniversary lister a few weeks ago. Initial start up process went great. I have run it probably 2-3 times since along with my others. I try to run my engines at least every other week or so. This lister is running great, it looks awesome! The craftsmanship is amazing! I’m impressed with the lister along with my others. It definitely won’t be my last purchase. I have more in my wishlist. I’m actually waiting on the electric powered three wheel Benz as I type this.

Five stars for the product and five stars for customer service. I have purchased several of the model steam engines from ENGINEDIY and they are all very impressive. The engineering and manufacturing tolerances are very high quality. All parts fit together perfectly. The models have been a pleasure to build and operate. Also, I have found that customer service of ENGINEDIY is excellent too. I made a slight modification to this particular model by using coiled up oil lamp wicks in the burner to heat the water in the boiler. I find this works better than cotton ball type wading which usually lasts for only one run.

When I received the Retrol SE-3, I was impressed with the box and packaging. During the building of the engine I was very impressed by the use of real ball bearings and that there was a WORKING governor. I have many antique and new steam engines and not one of them has a governor that actually controls the speed of the engine.
This would be a 5 star review if were not for the steam valve being frozen and not turning. I applied oil which did not work, but I was able to get the valve working by applying heat with a hair dryer. This engine is one of the top five in my collection!

The cart looks good and is a change from the spoked wheels. Quality is not as good as the spoked set, not as well made.

Absolutely obsessed with this high bypass model turbofan engine
-It was a quick build roughly an hour to complete
-Informative instructions that are clear and easy to understand (including common mistakes or errors)
-Decent build quality for the price (PLA plastic with metal bearings)
-Comes with everything you need including tools plus plenty of left over screws - though most of it is prebuilt or just clips together
*Something to note is this is not a functionally accurate replica of the RR Trent 900 as there is no HPC (High pressure compressor) present at all and is missing 3 stages from the IPC (intermediate pressure compressor)* If you are looking for a 100% accurate Trent 900 this is not for you otherwise if you are after just a general turbofan for show and to see all the internal components working of a fanjet then this is for you. Highly recommend especially for the price point it was $120AUD which I think isn't too bad considering that it does actually run and the exhaust lights up red. Was nice to see it does come with its own charger cable just not the wall adapter.
It took 18 days to arrive from the day ordered to delivery in Australia which honestly wasn't too bad considering it come from Hong Kong.

Great product, thank you Enginediy.

I am delighted with my Lister D model, but on inspection I noticed there were 3. Small screws missing from the flywheel assembly, enginediy responded immediately and sent me replacement screws.

After filling it with oil, cooling water and fuel, it fired up right away with just one spin using a drill. I shut it down after running for 30 seconds, and it restarted effortlessly by hand.

Honestly I’m still trying to wrap my head around the quality of craftsmanship on this tiny, cute 68W alternator. I’m still waiting on my LS-V8 engine so I haven’t been able too test the alternator out. Once I get engine together I will test out the alternator and write another review. It’s pretty amazing

This was my first metal model and I enjoyed it. Much better than cutting out plastic parts and using glue. LOL. It took about 75 minutes to complete, The tools they provided worked just fine. All the parts were there, a few bags had extra parts (deliberate? accident?). I also bought the Spider but haven't put it together yet.

This eye-catching little Sterling Engine came fully assembled in a well-packed shipping container. Of all the more complicated Sterling Engines this one was, most certainly, the best value and is a fine example of the Beam-Engine system. At a length and height of six and a half inches it it small enough for a desk display but large enough to clearly appreciate all of its moving parts, in all respects. A good price, for good value.
Use Methanol/Mentholated Spirits for fuel: it burns cleanly and has no odor.

its a pretty tiny engine.
very well packaged,
no shipping damage.
runs right out of the box.
it starts mostly by flat strait hand rolling over the flywheels.
to clogg the carburetor for getting air out of the fuel pipe and fuel in ,
i made a little stick with a very soft rubber on it .( foto)
it works the same as you put a finger on the intake side of the carburator
a little help to get the air faster out of the fuelpipe :-)

This little press is a functional model and it's perfect for a shelf or desk. I love watching it operate, it's quite fast when you turn up the potentiometer. I would have loved assembling it however it came already assembled though that could be a plus if you are just interested in displaying it. I am happy with this purchase.

This HM02 Kit is just great, built very well and runs excellent, as soon as I saw this engine I wanted it, then I found the the Black Version, these engines are quiet and the best show piece a engineer could have, here are some pics of mine.

I originally ordered the silver version but was quickly told it was in production and the red was available and they shipped the next day, great communication. The fit and finish were great and went together smoothly. I would highly recommend this as an entry into the hobby. I plan on converting to gasoline soon.

I was hoping to illuminate sealed noble gas tubes with this product or a standard tesla coil for Spectral Emission demonstrations. This product was a qualified success.

This product worked silently with no visible electric arcs. It individually illuminated Neon and Helium tubes well, but did not illuminate Argon, Xenon or Krypton well enough to produce emission lines visible thru inexpensive spectral slides in a darkened room. I’d like to try it on CO2 and H. The unit got hot, but not enough to become an issue.

For anyone interested: Standard Tesla Coils (rated 10 and 20cm) illuminated all gasses well, but bright light from electric arcs and arc noise were too distracting to use as a classroom Spectral Emission demo. The bright arcs simply washed out any usable spectrum, and the noise was too loud to explain or discuss over.

Overall, for $40 this product worked well.

This engine looks very well made, with many great details. I'm very pleased with it.

Looks awesome on the base awaiting my engine arrival.

I have not got my engine yet but the base and the two tanks look awesome. Very high quality.

For a beginner like me. This model was the perfect starter. The assembly and operating instructions are clear and easy to follow. There are also plenty of YouTube videos out there for additional help. I love this steam engine and plan to build more in the future.

Although it is not finished, the build so far is flawless. No fitting issues at all and very, very clear instructions!
For everyone with interest in engineering, this is a must have model!
Ordering and delivery were outstanding!

Zero plain have great packaging, well detailed instructions and tools, all parts fits perfectly, could not be more satisfied.
I have bought other scorpions from other sites that are nice but instructions and some screws and bolt were shady.

The Zero plain is the gold and black and i have put another one bought on Alibaba with less detailes or preicsed parts, they look similar but i have put a closer picture on the dart, Black and gold is way more solid and detailed than the silver one thus the difference in price

Here are the instructions that was provided that didn’t show how to correctly plug the battery pack into the board. So then they said it was my fault that the board and motor got fried and that I should replace both at MY cost. Oh and also when I started to contact them about their horrible instructions they went on a “Spring Festival Break” which was very convenient. I wouldn’t recommend wasting your money on this horrible company. Also this is time 2 of trying to post the review so others don’t get scammed as I have.

Après de multiples recherches sur REVOL, je suis tombé sur ENGINEDIY, pour finalement jeter mon dévolu sur TECHING.
Les vidéos m'ont confirmé mon envi de jouer à l'apprenti mécanicien.
Je viens de finir mon premier modèle DIESEL vraiment réaliste.
J'attends avec impatience mon second moteur commandé chez vous: le RADIAL 5 CYLINDRES!
Délai de livraison: OK
Conditionnement: OK
Suivi: OK

I haven't started it yet but packaging is perfect, instruction book is very complete, all parts are well separated and clearly marked but like the picture shows, i'm doing another one (Black and gold scoprion )before the Big dude but i have no doubt it's going to be a very solid piece. Same brand and everything fits together.
