My first 3d puzzle!

I enjoyed myself. This puzzle was perfect for a beginner. Shipping was fast, price was reasonable and its missing no parts. The instructions are easy to follow. My only issue is in the beginning it doesn't specify to use the little baggie of nuts for the A1 and there were no provided mounting screws for the maintenance platform, but I was able to use 2 different screws and nuts from the spare parts. I will be trying others soon.

Manta Ray Kit

I have been building models and kits for my entire life (I’m now 73)! I just completed building the Manta Ray Kit I purchased from enginediy- it took me about 3-4 hours. It is one of the best engineered kits that I have ever put together- everything worked as it should upon completion and it by far is one of the best looking! When turned on the movement conveys a great simulation of the movement of the Manta. I recommend this kit to anyone that likes a nice build

It’s not the attention to detail like the jet engine

Just received this engine, on first glance, parts look amazing but instruction manual for assembly leaves a lot to be desired. No parts labeled and a lot left for interpretation, along with the fact that you will need a magnifying glass and careful and precise interpretation of the instructions. The parts are of high quality but assembly instructions leave a lot to be desired compared to the jet engine that was assembled prior too

very good

Wirklich gut gearbeiteter Motor, lief auf Anhieb an. Der Hit and miss Zyklus war schon perfekt eingestellt, der Motor hat schön lange Aussetzzeiten. Gut Ölen ist wichtig.
Sehr empfehlenswerter Motor, läuft ca. 20Min mit einer Tankfüllung. Als Kraftstoff habe ich Feuerzeugbenzin mit 5% Zweitaktöl verwendet.

tiny but strong

this tiny sparkplug makes a good "fire" within to the minimum from the CDI.

Superb little steam engine

This is an amazing little steam engine. It builds perfectly and runs with no effort at all. Quite quiet too. I used about 10ml of ethanol as fuel and it ran for about 5 mins, with 50ml of water in the boiler. Not difficult to build so suited to a beginner too. YouTube video placeholder
Fantastic model kit

I've reviewed this kit for Model Ship World, here:

Absolutely fantastic, fits perfectly and is a VERY high quality model kit. Far better than I thought it would be. YouTube video placeholder
12V DC Generator and HM-01 engine.

I bought this mini generator to run with my HM-01 hit and miss engine. It arrived boxed and well packed and is absolutely beautiful. It is really well made and finished. I’m in the process of making a slide to mount it on as I think the belt tension may be critical to smooth running. I recommend this product and will update this review with new pictures when I have finished the slide.

Nice engine

the engine was well packaged.
no damage was seen at the cardboard box .
she runs out of the box.
filled with 6cc of alcohol(ethanol),
all movable parts are gently oiled
without the piston and the flat brass sheet in front of the cylinder.
the base of the tank is very nice made
and looks very fine as a part of this engine. i'm glad to have this .

runs very vell

the engine runs very well, interessting piece of technik. I use lighter fluid with 5% two-stroke oil. Shipping to Germany took 2 weeks.
I have fitted an 3d-printed exhaust that has reduced the nois by half.
All in all, a highly recommended, reasonably priced motor.

Amazing kit with reworkable assembly instructions

I think the model is fantastic, it works perfectly, the size is just right, the material is high quality. My only concern is the assembly instructions, a model kit of this calibre would come with a similar calibre of instructions. It is only for this reason that I have given it 4 stars, with a heavy heart, because otherwise it would be worth 5. YouTube video placeholder
Very cool see thru engine

Runs very well, had to change the spark plug cap because it kept falling off... but runs well I'm still breaking the engine in with a rich mixture and very happy with my purchase.

One of a kind, non compressing, 3 stroke engine.

I added a three way valve to the fuel line and was able to adjust the mixture perfectly. Check out the video. If you like odd gas engines, this is one of the best odd-ball engines you can get, ready to run out of the box.

Retrol HM-01 Hit and Miss engine.

This was the first model engine I have built and I’m delighted to say everything went together beautifully. The components are well made and apart from removing a few burrs here and there they all assembled just perfectly. I picked up a few tips from the experts on YouTube along the way and enjoyed the challenge of getting the ignition timing just right. I have found lighter fuel (Shellite in Australia) mixed 40:1 with 2 stroke oil much cleaner burning than petrol and oil mixed at 25:1 as recommended in the instructions. Easier to start as well. I would like to see a battery box supplied with the ignition set and details of the batteries required. Also as others have mentioned, a longer HT lead to the spark plug is needed. Altogether though a beautiful well made engine that I really enjoyed building. Any suggestions what to build next?


Very nicely made engine, it looks fantastic and runs well

ENJOMOR V12 Engine GS-V12

I received my Enjomor V12 Engine GS-V12 approximately two weeks ago as expected after pre order in December as usual ENGINEDIY were excellent in both processing my order and in dispatch. After an approximate two week delay on the promised delivery, which I totally expected being pre order and the time of year, the unit arrived in a well packaged box that contained a plastic storage box for the engine, not quite as classy as the V8 wooden box of the V8, but the engine will probably never be put in it especially when the accessories are mounted. The accessories for the engine comprised of a set of 3D printed black painted extractors, headers to our US friends, gaskets and bolts for the same ans a separate water pump complete with bolts brackets and belt. Besides these ENGINEDIY had had a special offer of a starter package which was essentially the V8 package started kit basic but contains some things needed. The engine looks great and I an very happy with it. It is well machined and assembled and appears well designed with some of the features like four valve heads and twin distributors, I would have thought twin, like the V8, or even triple carburettors would have been a more exotic touch but possibly harder to set up. I will let you know more on quality, fits and design when I disassemble some parts and suspect like the V8 it will require some minor re-engineering and hand fitting to make it more bullet proof. I will get to this when work and time allows but I can tell you I am very happy with and applaud what they have produced as they have done a great job. I have looked at the V8 factory base and will possibly look at mounting the V12 on one of these as some dimensions work well, so the V8 and V12 look like a set, I will be looking for some pricing from ENGINEDIY as they are always great to deal with, again thanks Lucas. I think the base will work well with some modifications and additions. I have not started either engine due to work constraints but have started some CAD design in documenting parts for the future if needed but also to improve the induction to better direct induction, using individual carburettors or possibly even fuel injection but the making of the prototypes will be a way off at this stage. If you are considering buying one of these V12's or the V8 don't hesitate as they are great quality and value that they or you can improve even further given the time. As for ENGINEDIY excellent as usual and highly recommended.

The result is very nice, some parts are complicated to assemble, but it can be done with patience :D
Unfortunately 3 pieces were missing to finish it, but they told me that they will send them. 🙂

Desk Top Mini Tesla Coil

Performance is huge for the size of this device. The arcs are greater than 6 inches (15cm), this is far in excess of what I expected. Good job.

Awesome little motor

I first saw this engine on Youtube and decided to get it. I got it for my birthday last month and built it up right away. I ordered everything needed for startup and was ready to go. Turned out more amazing then expected. Very good Sound and fast startup compared to usual 2 stroke nitro Motors wich I used before. It was one of the Most amazing Things I have built. Right kow I am preparing it to built it in an rc car. I am considering buyin other toyan engines too cause they are a lot more fun and amazing then usual 2 stroke.

The best Turbine Model available

Fast delivery and the parts are very well packed.

The instruction manual with step by step instruction makes the assembling easy and I could spend a couple of hours working on the model.
The parts are very well designed and beautiful in shape and details.
Only the plastic parts (needed for the see through parts) aren’t that exact and needed a bit of trim.

A well designed Model with a very high quality standard

Greetings Patrick

Impressive to say the least.

It's much bigger then expected. About 75% of a beverage can. Yes there are a few minor scratches but will work perfectly in my needed application. The fuel level markings would of been better if they were in Black as it would have better contrast on the Silver than the White numbering.
It will be used in a shop diorama setting with a running Emojor Hit and Miss engine and G Scale railroad workman figures.
Runtime on this engine with full tank works out to be just over 7 hours!! Too cool.
When I need a fuel tank for other projects, will definitely order again.
Thank you.
