Customers frequently praise the exceptional overall quality of the mechanical models and miniature engines, noting that items consistently arrive in good condition and function correctly. Consumers also value the incredibly helpful support team, appreciating their continuous dedication and remarkably fast response times when handling various technical inquiries.
However, some people mentioned experiencing significant difficulties with customer service, describing unhelpful interactions, prolonged delays, or slow communication during product troubleshooting. A few reviewers additionally noted receiving shipping packages containing items with missing accessories or broken internal parts that required subsequent replacements.
Stirling kit is amazing company I had few issues and they responded with solution very fast same day.I would highly recommend their products high quality with great warranty. THIS is company that will shop in future for my hobbies.
Product arrived promptly and was well-packaged. Unfortunately there was a part missing but that is the manufacturer's fault. The one good thing to come out of it is that I was able to experience customer service for myself. I dealt with Mona and she was very responsive and helpful and resolved the problem with no fuss.
With Stirlingkit, its difficult to deal with customer service. They give you the runaround. They take their time responding if they even respond back. I tried to contact them about missing items from my order and after 2 weeks , I havent heard from them since . This is regarding order 53091 . I am missing 2 batteries that I ordered. I will place a dispute with my creditor to generate a charge back. This will put a negative impact on their credibility.

We are very sorry. What did we do to you? We are in a different time zone, which is why we didn't reply promptly. Also, what's wrong with the helicopter? Could you provide us with a video? Our technical advisor can help. Didn't you receive the battery? We shipped it in two packages. The helicopter came with one battery. The other battery was in a separate package. Both packages show that you have signed for them. The tracking numbers for the two packages are: YT2609800702609722 and YT2609800702802814. The tracking information shows that you have signed for both packages: https://t.17track.net/en#nums=YT2609800702802814,YT2609800702609722
I have had nothing but good experiences with Stirlingkit.com ! I am amazed and very happy that they will ship small engine replacement parts and not charge shipping. They are now my go to for parts for my engines.
I bought the RETROL HM-01 7cc Model Hit and Miss 4-stroke Horizontal Internal Combustion Engine. Assembly went smooth. Engine fired up and ran like a top. Have an issue with the CDI Ignition that came with the kit.
It just quit! So now I am using one of the CDI's that I have for other engines.
Stirlingkit is aware of the CDI issue, and I hope to get a replacement for it soon.
All said and done, this is a 'sweet' little hit and miss engine.

Purchased one of the hit & miss engines and it’s very nice, I had a issue with a part not fitting properly and after a couple emails to customer service I was sent a replacement, surprised how quickly it arrived! Happy customer, thank you Mona and the rest of the crew at Sterling kits!
Customer service is atrocious. They seldome answer emails, I also have been told an item will be shipped and that was not so. On my original order I did not receive everything I needed and did not realize it, and I even offered to order and pay for what I still needed and that went nowhereI finally had to track down hardware I needed and buy it myself as the lady I was trying to work with was LESS than helpful. I am still trying to find an answer to my original question as it was not covered in the ...instructions, so Buyer Beware!

Those models that work, work very well. Some have serious problems. Working with Sterling Kit customer service is a nightmare. I bought a Hit & Miss that will not run. two years later I'm still trying. I bought a horizontal mill engine, it runs but can't run it because the water pump doesn't work. It does not seem to develop enough pressure. I try working on these engines when I find time.
Shouldn't have to waste my time on their problems. I would like these items replaced with working models.

Your engine has a problem. Have you contacted us? For any issues, please contact our customer service directly.
Order#51085 The order shows as paid over $2,600 and unfulfilled on my account with you. Ordered and paid on 01/09/2026. This seems like an unreasonable amount of time for the order to be unfulfilled. I will cancel the order and require a refund if something doesn’t happen very soon.
I am quickly losing confidence that this is not a very expensive scam.

We are very sorry. Are you referring to your order #51085? The CISON V8 is in high demand and short supply. Production is nearing completion. If you wish to cancel, please contact our customer service. We will cancel your order. We sincerely apologize for any inconvenience this may have caused.
Building of this 3D printed metal jet engine was challenging but I enjoyed it once I understood the instructions which were very helpful. I would love to see an upgrade kit with some lights and sounds. Also I think it would be nice to add full 360 degree stators to the HPC and HPT sections of the turbine.
Good luck getting spares or replacement parts. Terrible customer service.
Initial sales are generally fine but after spending out on a nearly two grand cison v8 pro and various other related parts I have found the aftersals experience absolutly dismal. I have been trying for months now to get spares for this engine. I have got close a few times to getting the parts I need only to find that communication from stirling kit stops and i'm back to the start again. So much for life time warrentee and comints like we do care and we will sort you parblems out.... Its all lies and im not even sure if im talking to a real human or an Ai bot, it terrible. technical support is almost non existent at best, and some answers are technically not even correct. If only I could actually communicate with someone with true product experience and technical knowledge. so now I have an engine that needs parts to run again and stirling kits customer service doesn't seem to care about you after you have made a substantial purchase. After months of trying im not sure if i will ever get the pars i need to get this engine running again.

I purchased order #52299 on Feb. 22, 2026 with tracking number YT2605400701858679. Here's in lies my issue. This was my second Yu Xiang purchased after a nightmarish purchase of the F11S. I felt maybe I did something wrong with the 1st one and thought... "I really like the style and technology so I'll give it one more shot". Not to my surprise same issues (Radio & RX communication issues, out of control yawing) with the second one and I vowed NEVER to purchase another Yu Xiang product. It's sad because I truly became connected to the brand and had high expectations after seeing all of the paid representatives boast about how awesome it is. Just was't my experience. Never an issue with my Flywings, RCA ERAs, only Yu Xiang. Sad.
