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.

Pretty Darn Good
Format: Kindle
So I’ve been on a omega kick and this definitely hit the spot. Madison was frustrating at times with how she acted towards Lucas, Gray, and Rian. It was like she said towards the end, she didn’t believe she deserved nice things. It would have been nice to hear from her best friends again. They kind of were there in the beginning and the gone except for mention of text messages received from them. I feel like her friends would have been great help in encouraging Madison to go with the pack and never give Brent another chance because he was toxic. I loved Rian. His personality was awesome. His humor. His ability to make Madison comfortable whenever she was feeling overwhelmed. And the fact he fell for her and she fell for him first. They are cute together. I do feel like Lucas was the odd man out though. Like Lucas didn’t develop as much of a relationship with Madison. I would have really liked to see more development in the relationship between them. It was also the same with him and Rian. There is really no relationship displayed. Most of the relationship being displayed is between Rian and Gray. Nevertheless, I loved reading about the dynamic that came to fruition during the entirety of this story. Madison finally got her happiness. And Brent finally got punched in the face. Everyone got exactly what they deserve.

Pack's Promise was okay but not great
Format: Kindle
Pack's Promise was okay but not great. I won't recommend it to anyone that I know. PRO: * Very likable characters * Lots of steamy scenes that are written very well * The spelling and grammar are good * The punctuation is good with the exception of using hyphens instead of commas. Lots of hyphens. Lots and lots of hyphens. CON: * Almost no interactions with any characters outside of Madison and the pack * Nearly no plot. They meet, get together for a heat, agree to make it permanent, done * Quite a few typos such as extraneous words, missing words and words out of order THINGS TO KNOW: * More steamy scenes than storytelling * A lot of MM & MMM, some MFMM during heat

Fluffy and Nice Omegaverse
Format: Kindle
… this would have made 5 stars but for 2 reasons. A.) there were quite a few typos; misspelled words, missing quotations, “the his” mistakes, and various signs that maybe a proofread would do good. B.) the writing was quite textbook. Late blooming omega is struggling with her new self, finds a absurdly wealthy pack of alphas, every thing is almost insta-love but she resists, then decides to love herself and let everyone be happy. Rian was my favourite (obviously the author’s favourite too because he got the most page time) but I wish we could see more of his CEO side? He went to work maybe ONCE the entire time. Gray was supposed to be the “growly one” but he turned out to be puppy dog. Lucas was a genius brainiac doctor - but also super alpha with an aggressive hindbrain with a breeding k*nk?? And then there was no actual “breeding”?? Spice 3/5 - normally omegaverse books are super high on messy smut but this was tamer. Romance 3/5 - insta-love that was then resisted because of personal hangup’s Plot 2/5 - weird paced head hopping, showing the same scene from different POV’s that made me feel like it was 2 steps backward, 1 step forward. Humour 4/5 - there were a dozen lines that genuinely made me chuckle out loud Would have been five stars but the lack of proofreading and the predictable plot made me unable to get up to ADORED IT level - four stars is still and official ENJOYED IT, y’all. This isn’t a bad rating. The “Club Heat” has intriguing possibilities so I’m going to give the second one a shot.

Wow.
Format: Kindle
Okay I’m usually not one for stand-alone’s I’m an avid series reader but my goodness am I so happy I read this! This story was brilliant & so absolutely mesmerizing. I loved reading about each character and their struggles as well as what helped them to move forward. The ending definitely brought tears to my eyes so hard. I truly wasn’t expecting some of what happened in this story. There is about to be a spoiler I am going to reveal so please stop reading if you don’t want the spoiler !!!! ⚠️ ⛔️ ‼️ I loved that the author didn’t do what most authors do with irredeemable male characters. I truly was hoping that Nate Jr. would be apart of the pack after the way he treated Astrea bc he truly didn’t deserve it. Though I must say you did a wonderful job or redeeming him as a person. I cried my eyes out when he walked into the story. I was truly terrified he was going to be a bad guy to the end. However you truly did him such a justice by having him realize his faults & having him redeem himself in the most wonderful way. I’m so sad that he didn’t get to hear how much his brother loved him & forgave him before dying. But again you wrote that ending so beautifully & I just can’t express how much I loved this story & how you took a different route than most authors I have read have. You are a remarkable author Cinder Blaze & I thank you generously for creating such a masterpiece.
