Best kit I ever purchased from stirlingkit what I consider a very well made with excellent instructions!
In keeping with Teching high quality and craftsmanship, the 1st Automobile was a pleasure to build.
Great helicopter, love the size flys awesome and battery last a good 12 minutes. Perfect for the RC airfield or just flying around the yard. Very happy with the purchase of this helicopter. Details are amazing GPS is great for beginners and the manual mode is great for intermediate or expert pilots. This helicopter is an all around home run.
Wow - a miniature turbofan engine that works just like the ones that power jetliners! It is very well built and looks great. When combustion starts inside the engine you can see it spin up to high speed. There are a lot of turbofan engine kits available, and some spin powered by an electric motor. But this is the only one that actually functions like a real turbofan engine. Well worth it!
Very high-quality engine kit! It was the most satisfying kit I have ever assembled! Take your time installing the O-Rings for the cylinder sleeves, lubricate them very well with grease or oil and be careful after getting them through the top O-Ring. They will bind up really easy and makes it very hard to get them down to the two bottom O-Rings or they will go down to fast, and you will damage the bottom O-Rings. I damaged two O-Rings and had to replace them. I was looking at the bottom of the sleeves after they were in all the way and there were small pieces of the O-Rings at the bottom showing I damaged them. After that everything was easy and very satisfying and fun for me. I repainted the outside of the engine block and valve covers Black and removed the orange paint from the front timing gear cover and the oil pan and polished them. I also replaced the red 20-gauge spark plug wires that comes in the kit with blue 16-gauge wire that was the same OD as the red wires in the kit (approved by Stirlingkit customer service). The larger inside copper wire when stripped, fold it over double fills the entire inside of boots and you will not ever loose connectivity for the spark and you don't have to solder or make any special ends for the wires!!!!! Stirlingkit is a great company with outstanding quality products and customer service!!!!!!!!!
I had fun assembling this V8 motor, quality was good in this price range. Assembly Manual has some problems but nothing you can’t sort out with some extra focus. Took me about 8 hours in total to the final assembly with the supercharger and some little painting.
Conclusion is, YES it’s worth buying if you are into assembling miniatures.
Très belle expérience avec le CISON V8 v1.1 tout l’assemblage était excellent.
I own many of these little Mini Steam Engines,The Quality can't be beat,It arrived fast,That was GREAT,I think I will get another for my Brother.
Thank you Stirling Kit for a Wonderful Product.
I think it's a great kit, wish I got everything to make it run, still waiting on some stuff.
Great product as always. Very well built and comes completed out of the box. I give this product 5 stars!! AAAAA ++++++
Great product! They shipped it quickly to start with and arrived in quality packaging. The kit itself was clearly extremely well manufactured. Precisely machined parts! Only other comment would be that the instructions could be better for the complete amateur like myself! Overall, excellent!!
Have had my lister D for 2 weeks now. It arrived in perfect condition. It starts easily, but you do need to crank it at a fast speed, and check that the spark plug lead is making contact with the spark plug. The instructions say 5/10 ml of engine oil, but 10 ml is too much and you will have oil leaks from the crank shaft. Reduce to 5 ml and you won’t have a problem.
The engine will run for at least 40 minutes on a full tank of fuel. I have run mine for 5 hours now without any problem. Have changed the oil once.
Thanks to Okmo / Retrol and Stirlingkit for producing a excellent engine that starts easily and runs well.
The Lister type D, which OKMO and Retrol model is set off beautifully by this top quality, historically accurate kart.
You might like it cheaper but it's solid and the box is big. Add retailer margin, and you'll see why this small-run product of this quality is not cheaper. Mine could have used different screws as the holes for the ignition box seemed too short and the engine mounting holes too big. Tiny issue. Easily fixed. Built VERY solid
Quite an advanced subject to model and here in mid 2026 OKMO and Retrol have gone the "extra mile" with superb design, excellent quality, great paint, useful accessories and a fun experience adding the kart. This would be a tricky engine to build and tune and I'm glad Jin at OKMO didn't rush. WORTH THE WAIT - a most recognizable vintage engine!
Love this engine! Looks amazing and runs great.. I can just sit and stare at it for hours.. lol! Thanks Stirlingkit!
Worth the price, no better place than Stirlingkit to purchase from
The first one had issues , possibly used and returned. Stirling indeed took care of everything and shipped me out another complete model.
Now, the review…..
This is a true turbo fan engine that uses air start like the real jet engines!
This is a model, it will not fly a plane nor was it intended to , you can not start up a real model jet engine in the house, this one you can!
Very realistic, it pics up speed after it lights off, compressor section in model works.
Very quality build, it sounds great and takes me back to the 80s on flight line working on the A-10s 🤠
All I can say is this is a sweet Hit and Miss engine. Assembly was straight forward. Fit and finish is good. It starts and runs quite well. Had a small issue with the ignition module (CDI). It crapped out, but that happens sometimes with new electronic components. Stirlingkit is sending a replacement.
The solar powered diffuser is a great addition to your vehicle or any room in your house. Very nice looks and it’s cool to watch the little flywheel spin as it fragrances the area. They make great stocking stuffer gifts for Christmas..
Hello, great Kit arrived. Works well. But the glass tubing has cracks. Can you send me some glass tubings? Can i get it on Garantie? what would be the price for the Glastubes?
Thanks in advance

Since I worked in electronics it is an interesting motor. Should be enjoyed by any one interested in science.
This Cison V8 gearbox is absolutely beautiful all metal construction with steel gears,aluminum body and the servos are included 👌
From the moment I pulled it out of the box you can feel the quality in the weight
This is one solid unit and the gear rotation is very smooth.
I really enjoyed the plug and play setup and the installation was quick and easy the gearbox has been working great with no issues the shifting is smooth and the gears have good engagement.
This Cison gearbox and V8 combo is perfect to install into a SCX6 chassis.
You can make it go faster if you are making a 2WD hotrod like I am.
This is a great addition to the Cison V8 engine and now makes it easy to install in a RC.
Just received the F11N. The maiden flight was great and I was really impressed with the position hold on this helicopter. Stirling Kit sold this helicopter at a great price (25% off) and shipping was on time without delay.
Looking forward to flying more helicopters from Stirling Kit.
This engine was fun to assemble. Once assembled the engine operates great and brings joy to all who watch it.
After building the Semto twin cylinder engine I decided to add the 2-in-1 upgraded exhaust pipe, and I really like the look of the engine a lot more. Worth the money.
