Miniature Engineering Models that Run on Fuel


This small silver engine, called FL4-175, is a 17.5cc water-cooled flathead side-valved engine that burns gasoline on CDI ignition. A small amount of oil is added to the crankcase for internal lubrication and caster oil is added to the fuel for upper end lubrication. Aluminum CNC precision machining is used to make the main body of the engine. It features bi-metal piston rings made out of cast iron, high-performance hardened cylinder liner, one-piece crankshaft. Sandblasting oxidation on the engine surface makes a good metal texture and sense of mechanical engineering.

As we all know, a flathead engine is also called as a sidevalve engine or valve-in-block engine that is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine. In the past, Sidevalves were widely used internationally by automobile manufactures from the late 1890s until the mid-1950s but were replaced by more efficient overhead valve and overhead camshaft engines. 

To provide an impressive performance, this unique FL4-175 engine features a simple and reliable construction, a compact small size but with large displacement. It's a good combination of retro and modern machinery. 


Long stroke and high torque

the engine is designed with a side valve structure for lower gravity and lighter weight and offers higher torque output based on the long stroke. Having higher torque allows for greater horsepower at lower rpms.


Responsive and powerful

the engine boasts metal stainless steel integrated printing inlet pipes and exhaust pipes and independent single carburetor for easy calibration, more sensitive throttle response, deep and powerful sound.  


Effective and lasting work

the external oil pump is utilized for crankshaft supplement and superior independent lubrication when matched with mini oil filters. The engine is cooled with water cycle for longer operation and lifespan.  


Convenient ignition

the self-developed four-cylinder electronic igniter with a compact size and strong anti-interference makes the engine ignition more stable and more friendly to remote control electronic device users.  


Upgrade

the oil bottom shell is reserved for observation window which is modifiable into a transparent window for real-time crankshaft operation observation. The flywheel end is reserved for the installation of simulated automobile mechanical manual clutch for users to upgrade.  


RC compatibility

the lightweight engine is compatible with RC models and is an incredible "heart" for low torque demanding 1/8 and 1/10 scale model crawlers.

 


Collection and gift

the engine makes a perfect addition for machine enthusiasts, engine model aficionados and collectors, an excellent choice for RC oil models and a high-end personalized gift for family and friends.


.Note:

base, CDI igniter, spark plugs, battery and oil filter are not included. buy it here.

i recommend you use the 2S-3S lithium battery (7.4-12V battery). Please use the engine in line with the instructions to avoid damage by improper operation. Please feel free to contact us if you have any questions.

“My heart bows to you and you only, Huntress.”
Format: Kindle
3.5 🌟 This book popped up in my KU recommended reading suggestions and the synopsis sounded like what I was in the mood for. I'm so glad I took a chance on it. I went into this knowing absolutely nothing about it and ended up really liking it. I love when this happens. The main characters are likeable and I easily found myself rooting for them. There is a mystery element to each of their backstories that I enjoyed watching unfold and can't wait to get more of. Wolf, in particular, has me fixated. Love him. I found this to be an entertaining, addictive read with a plot that moves along at a good pace. It reads so easily I found myself very reluctant to put it down. Lots of twists and turns and the angst is there. A good set up for the next book to come, for sure. My issues with this book....the dialogue feels a bit juvenile at times and there is a repetitive over use of a particular word phrasing that I found myself giving the ole eye-roll to. There are, without a doubt, some pretty cliche moments that gave me a bit of the cringe. I think this could've certainly 100% benefited from more depth regarding the world building. Perhaps the world building was sacrificed to keep the pacing quick? Just a guess. Also, the lack of consistency of character for the FMC was really evident and so she feels quite illogical at times. Overall, this was a fun and enjoyable read that hit the spot well enough for me. That ending certainly has me impatiently pining for book 2!

Interesting take on the genre
Format: Kindle
True rating: 3.25 ⭐️ I enjoyed the fresh take on the genre. The best way I could describe the setting and world is an apocalyptic dystopian version of Farie where vampires, fae, and angles struggle to survive in what is left of the world. It was definitely interesting throwing the academy/hunger games aspect into this world as well. Even though I guessed the final reveal early on in the book, I kept hoping I was wrong, and it would take a surprising turn. While the "plot twists" were a bit predictable to me, I still enjoyed the ride this book took me on. Another downfall for me was the plot holes in the world building... I.E. if society has fallen and the world is in the aftermath of war, how are there trains running around the world? Just to take young adults to the trials to get into the golden city? How is the train maintained, the tracks clear, etc? However, I did enjoy the FMC & MMC and thought they were fleshed out nicely. I also enjoyed the side characters but wish some were developed more like Ashalin (sp?). I do find myself rooting for the MCs to succeed and find happiness together, which is obviously an important aspect for romantasy. Overall, was this an earth-shattering, mind-bending, terrific piece of literature? No. But was it the worst thing I've read this year? Also, no. This book has, to me, the bones of a great read & just needs a bit more to push it from an alright book to a great book. Overall ratings: Plot- 3.5⭐️ World building 3⭐️ Spice 2.5 🌶🌶 Main characters 4 ⭐️ Supporting characters 3.5⭐️

great book
Format: Kindle
I am really excited to meet the author at the book retreat this month. I really enjoyed this world that she built and most of the female main character Huntress is so awesome. She goes through a lot in this book and the ending; wow! I wouldn't have even guessed. I highly recommend everyone to read this book. I have been so lucky this year that almost all the books I have read have been, so far, 5 out 5 stars.

Fallen for the Fallen Angel – A Guilty Pleasure Worth Every Page
Format: Kindle
There’s something deeply irresistible about a dark academia or trial-based setting, a brooding and arrogant fallen angel, and a fierce heroine with enough sass to go toe-to-toe with him. Wings So Wicked is exactly that kind of book—and I devoured it in just a couple of days. To be fair, the plot isn’t groundbreaking. If you’re looking for something fresh and innovative in terms of storyline, this might not be it. But if your reader heart beats faster at the mere mention of enemies-to-lovers, jealousy-fueled banter, magical trials, betrayals, and forbidden tension—you’ll feel right at home. It’s like catnip for those of us with this particular weakness. The chemistry between the leads could have used a slightly slower burn to make the tension sizzle longer, but I still found myself completely invested in their dynamic. There are moments and phrases that feel a bit cheesy or underdeveloped, but honestly? I didn’t care. The vibes were exactly what I wanted. This book isn’t trying to reinvent the genre—it’s here to give readers like me what we crave: high-stakes magical drama, angsty romance, and the thrill of watching a badass girl and her brooding counterpart clash and spark. If that sounds like your kind of story, Wings So Wicked will hit the mark. Here’s hoping Book 2 turns up the heat and keeps the magic alive.

my new favorite book
Format: Kindle
Ok so I never write reviews but this book was so good I felt the need to write this. Firstly your introduced to Huntyr you see her closed off hard core badass than towards the end you see the most subtle change and growth it’s amazing and the enemies to friends to lovers was just perfect, AND THE TWIST AT THE END GOT ME GOOD! You see one spicy scene the whole book but it doesn’t even MATTER BECAUSE THE BOOK WAS THAT GOOD. I’ve read 85 books in 2023-2024 so far and I’m pround to say this is my all time favorite. I’m so excited to read more of Emily Blackwoods books, this was my first time reading one of hers and I’m glad I did because HOLY!! Well done Emily well done
