Great looking engine

This is my first model engine, and I was a little sceptical on spending that much money especially with the exchange rate, and wondering if it would actually arrive. But I must say that Stirlingkit did a great job in making the process go smoothly. The well wrapped package arrived earlier than expected with no damage. On opening the package I found everything well packaged in foam cutouts and all smaller items in well labelled plastic bags.
One problem was found, the plastic ignition trigger assembly was broken in half with springs exposed. (disappointed). But a email and photo to Stirlingkit and next morning I had a response from Martin explaining it was a known fault and a revised replacement part was sent. Big thanks to Martin at Stirlingkit.
I made my own engine stand, ignition and battery box, and small fuel tank.
I’ve had the engine running, but it will not run at slow speed, I will have to work on retarding the ignition timing. A work in progress hopefully with good results. The engine is well made and goes together easily.

Perfect engine

Im not kidding when i say how awesome this tiny little guy is. Right out of the box she was ready to run. Add fuel mixed with oil. Add water. Plug in the battery and off ya go! She has never failed to start up. And always happily idles away. Its the perfect desk engine made by an amazing engine company MUSA.

Shockingly capable little starter!

Dont let its very simple design or parts fool you, this thing starts almost all of my engines no problem! I have always used a drill to start my engines, it has never failed me asides from being quite litteraly overpowered for starting such little engines.

I originally did think about picking up one of these to try and use for my Musa or Retrol engines.

But! I got gifted this little guy with one my my engines by suprise.... And I actually kinda like it! Its pretty darn capable! Almost.

It comes with a charging cable of course, the 4 screws on the back reveal the battery and cable.

The button cover and mini starting rod come in a little baggie. this originally threw me off, but i wasnt going to let a simple button cover i thought was lost put this thing down. But it does come with them!

No instructions needed, charge when you need to. And conveniently start any wood base mounted engine with ease. It starts my M16, R29, Retrol tractor engine, and my hoglet. And all in a package no bigger than the wood base these engines sit on. Without the bit its actually shorter.

Unfortunately. It does not have enough power to crank over the MUSA FV1A Reddog engine. So yer milage may vary. On what it can and cant do.

Id say pick one up if youd like a dedicated starter for the small engines! Beats grabbing the drill ever time!

Cisons best one yet!

Its one of the best engines Cison has come out with. Its a fun challenge to build as its a full-blown engine! This engine takes time to build, it has a fair bit going for it. And i love it! Let me set some important points.

-Dual stage water pump is brilliant. Each bank receives their own fluid to stay cool, they then join at the back and route though under the intake where it conveniently comes out the front of the intake manifold! The pump is also a gear setup, so no more lack of waterflow like Cison had with the L4. This is a massive improvement overall! Good job guys!

It has a fully developed oiling system so everything stays lubricated! By a small 3D printed metal tube. Its directly fed directly by the oil pump. This squirts oil onto, camshaft and crankshaft! Even the rocker assembly! That will drain past the lifters keeping them oiled, and back into the oilpan. This greatly prolongs the life of parts inside the engine! And when yer reving to 10,000 RPM thats very important. The pistons even have an oil scraper ring, which will prevent the engine from eating its oil, reduse sleeve wear by keeping proper lubrication, and reducing carbon buildup.

Having a distributor to adjust makes setting the timing much easier. Simply rotating the distributor will advance or retard the timing on the fly. No more having to set a hallsensor in the correct spot! The shaft being made from metal also ensures longevity of the distributor! The crank pulley even has timing marks to make setting the timing much easier!! Now you know where TDC is on piston one!

the engine is absolutely gorgeous, there are other small V8 engines out there from Howin, to Toyan even Enjomor. But Cison has knocked the ball out of the park with this one.

Building it you have this sense of awe, that something with such power, was made so small. The fact a litteral v8 engine can sit on my desk and rip away is still mind boggling to me. You chuckle a little thinking about it.

When you get the engine take a pause and take a look at the parts of the engine. Youll start to appreciate the ammount of detail and craftsmanship that went into this engine. Its smooth, solid, everything fits together like a really good lwell built engine set. It was done with intention not just because. It does not feel like it was hobbled together at all. Like they really took the time to make such a wonderful thing. You see it on the website photos, they went from an o-ring setup to a proper belt system. This is true craftsmanship. A whole other level of engine building.

And I only own this one V8 engine. I saved up for months to get this engine as my first. I have lots of other engines i love as well. But none have impressed me as much as this engine has. This raises the bar entirley.


How often can you say a fully functional V8 engine fits in the palm of your hand? Its mind boggling.

If you are looking for a proper SMALL v8 engine. As a desk toy, boat engine, or even to put in a square body. Beginner or not. I highly reccomend Cisons. I haven't gotten to start it yet as i need to wait for the mounts. But knowing how good the L4 was itself. I have 0 doubts this engine will give me issues. ill be eager as i wait! I reccomend you get one! You can even choose from 4 diffrent colors!

Amazing little engine

This engine is amazing, when you get the carb dialed in she just purrs away happily. Even after 10 minutes of various reving and idling. She never gets past 120F (40c) thanks to the water cooling tank on top.

Shes very quiet for the ammount of RPMs she can hit!

She can run gasoline! But that may be to harsh for this engine. A simple mix of coleman camp fuel and 2 stroke oil is perfect for this little guy. 75ml to 15 drops of oil is my mix in a tiny jar.

My only issue with this engine is not even with the engine. Its the spark control unit. They are prone to fail, i have had 2 die on me. I reccomend Howins Pulse Ignighter for a reliable spark.

Otherwise i reccomend the engine! What color is all up to you!

HM-01 made into a portable engine.

I immensely enjoyed assembling the MUSA RETROL HM-01 7cc, Model KIT which was easily accomplished. After I got it built, I needed to do more, like making it into a portable engine. I found the right wheels for the look wanted and fabricated the running gear. Adding a choice wood tray from Hobby Lobby finished off the display. Overall, a “GREAT” model from Stirling kit added to the collection. THANKS. **PS: Still looking for a functional model Windmill, and a side shaft cam stopper model.

Fantastic little runner!

Runner right out of the box. She is an awesome little engine thats surprisingly quiet for being straight piped.

She will take a few kicks before she gets going. And is quite sensitive to carb adjustments.

I only have 1 gripe and thats the spark plug boot. It does not stay pushed onto the tiny spark plug. This prevents some cylinders from firing. And a spark gap.

Otherwise id most definitely pick one of these up!

Mill engine

My engine arrived with the base in two pieces. Not very happy

Fantastic engine

Absolutely thrilled with this engine!🎉😍

The experience of building it was fantastic, and I'm grateful to Stirlingkit for both the high-quality product and exceptional customer service. Despite building it a bit later than planned, I'm thoroughly satisfied with the outcome.

Can't wait to order the new version of the l400! 🚀 YouTube video placeholder
The very best hit & miss model money can buy!!!

The Retrol HM-01 engine from Stirlingkit not only looks good but it runs great as well, So many of these models come from the factory set up to run as fast as possible, The opposite to what enthusiasts want, but they got it right this time.
The quality of machining of this engine is second to none. the fit/finish is perfect.
The wooden base really sets the engine off and is worth the few extra dollars to get it, Taking it from "Toy" to "Scale Model".
The engine fired up very quickly after the initial build without any issues.
It come with a glass drip lubricator (as prototype) for the cylinder along with two lubrication cups on the crankshaftshaft.
Overall i think this engine equals the quality of something you would expect to pay 4-5x the price for in the USA or UK.

It really is a no brainer, GET IT BOUGHT YouTube video placeholder
Timeless beauty

Wow!! This Cison V2 is just so incredible!

The quality of the FG-VT157 is fantastic 👌
I love all the chrome and the details of this engine.
The adjustable valves are a very nice feature, and lots of room for grease up top, I absolutely love the chrome valve covers.

The updated carburetor is perfect for this engine and very easy to adjust but the throttle arm is in a difficult position to install a scale airfilter.
I like how the timing is simplified only 2 gears instead of 5.
The Pistons are massive and there's so much compression.💪

Out of the box I still disassembled the engine and went over everything and I was very impressed.
The ground wire is incorporated into the hall sensor so no ground wire is needed and
I also followed Jon Cook advice and installed bigger resistors inline. Thank you for your work on the Cison V2 Jon Cook.
The FG-VT157 comes with 2 sets of resistors 3.3 ohm and 8.5 ohm I installed 19.7ohm on the 20k scale so far zero issues with my hall sensor.

I also wish that 2 capscrews 2.5 x 20mm was included for mounting this engine. (Hard to find).

Out of the box this engine has ran perfectly, no messing around, other than installing resistors.
If you love V2 engines the FG-VT157 with hemi head is the one to get.
Here is a little video, it's running a little rich for breaking in the idle is a little high to keep it from stalling.

Thank you Cison and the Stirlingkit Team for bringing us such a high quality engine that runs and sounds like the real thing 👍🙏😊 YouTube video placeholder
excellent kit and very accurate

A pleasure to put together, high quality and precise parts, nicely painted and it looks great!

Cool Jet cutaway engine

Spent a good amount of time putting this engine together and it turned out nicely with good details

StirlingKit DM 119 TurboFan Engine Kit

Excellent kit to assemble and understand airline jet engine construction. Principles of compression fan operation are visible in the cutaway view ports of the model. I added LED's to show compression stage temperatures. Blue color for lower temperature primary combustion stage ignition and amber color for high temperature secondary combustion stage ignition.

the best turbofan engine kits to build ever!

I'm a retired pilot. I was looking for something to build during my leisure time. and I find this turbofan engine kit from Stirlingkit. I'm doubtful at the beginning. but I changed my mind after I received the parcel, all the metal parts, and a well-packed metal gift box. every part is listed well in the different holes of the foam. the instructions are clear and helpful. I spent about 5 days to build it. not easy to build but it has some repeated steps, which means patience is required. It's worth the price. the best turbofan engine diy kits i have ever.

Love it!!

The Cison alternator quality is outstanding and was very easy to install on to my Howin l6 engine and it will power the cooling fan or small water pump.
A beautiful upgrade for any Engine. YouTube video placeholder
Toyan went a did it!

For once I'd say Toyan actually made a proper engine. The fact that this flat 4 is nitro powered is smart. Nitro has plenty of oil in it. There are some minor quirks with this engine that need to be addressed.

1 the carburetor setup. It leaks to much air past and must be sealed tightly or you will run WAY to lean. Or not suck up enough fuel at all.

2. The exhaust valve on the left hand side. Mine and some others do not seal fully, causing hot gasses to escape and make the head run way to hot. You may need to adjust the timing by a tooth or two untill it's correct. Or take the valve out and lap it. This should be done at the factory.

Positives. The tensioner for the starter belt. Absolutely amazing and needed. It starts up with ease like it's nothing. No more tooth jumping.

Cooling fan, absolutely amazing and works as intended. though I'd make it out of metal as at high enough RPM and it will grenade apart.

Sounds amazing! This engine screams "I'm ready to perform" if you have been thinking on getting it I'd say go for it! You won't be disappointed! With this one! I've ran 5 tanks through my engine and she still runs like new.

It's a fun DIY kit for any mechanic you know. Or for someone who simply wants a desk toy to tinker on.

New lamp

Very nice looking and it runs even better then it looks, made a display stand/lamp so it can be enjoyed when not running.
Not really impressed with the customer service. Took about 5 weeks, and many emails to get a replacment part for the part that arrived broken.
The engine is very impressive now that it runs however.

a beautiful kit to have on your desk

The quality of the materials is too good, every aviation lover should have this beautiful engine.
Plus it's too much fun to build your own engine.

V- twin pan head

First engine I have owned from this company. The machine work is beautiful this makes a great engine to run or even just display. A must have for any man cave or even a Harley dealership. For the money you can't beat it.

Father and Son Hit&Miss

These little engines are terrific! I have several, the red Enjomor being my first. These little mechanical marvels inspired me to purchase a full sized Hit&Miss. Pictured here is my 1.5hp, 300 pound, 100+ year old Alpha Delaval Hit&Miss next its progeny.

Excellent Hit and Miss Engine

This engine not only looks good but it runs amazing as well. The wooden base really looks great with the engine and is worth the few extra dollars to get it. The engine fired up right out of the box without any issues. I like the fact that it has a two speed lever. It come with a lubrication glass tank and two lubrication points on the shaft. Don’t think about it just buy it, you won’t regret it. YouTube video placeholder
