CISON FG-VT9 9cc V-twin V2 Engine Four-stroke Air-cooled Motorcycle RC Gasoline Engine

Note: the engine after 2023 is 15.7cc instead of 9cc. 9cc is the original one. our engine is keeping updated in every production. That's why sometimes you find it a little bit different from the original version. The newest batch of the CISON V2 engine has been upgraded from 9cc to 15.7cc, the same displacement as the Cison Shovelhead V-twin engine model. So the manual of this engine indicates FG-15VTS. After they are sold out, it takes another 60 days to re-produce them. So don't miss it. Buy it now.

Please note that the electrict starter motor is not released yet.

History Prototype

A V2 engine, also called a V-twin engine, is a two-cylinder engine layout in which the cylinders form a "V". People also call it a panhead engine because it's an overhead-valve Harley-Davidson motorcycle engine, so nicknamed because the rocker covers resembled cooking pans.The engines are arranged in a V configuration with angles greater than 0 but less than 180 degrees. Sometimes the cylinders can form an angle of 90-degree twin engine which is referred to as L-twin.These engines are used mainly due to their compact size, high power to displacement ratio and low end power/torque delivery. Since the late 1880s, the V2 engines have also been used for motorcycles and in several small cars. The most common V-twins are 45° Harley Davidson motorcycles,most of which are air-cooled engines, but they have water jacket engines and the VRod water-cooled engine as well. Inherent vibration is often associated with the V-twin mystique, but it's an unfortunate side effect of the most popular designs. Harley placed its two cylinders 45 degrees apart on a common crankcase mainly so the engine would fit into a bicycle-style frame originally intended for a single-cylinder powerplant. Unfortunately, a 45-degree Vee angle has a prominent vibration "signature." There is no doubt that most engine men think the soul of the V-twin emanates from shudders and quakes from the engine room.


.Impressive Simulation: The highly simulated classic look and elegant silver appearance recreates how a real motorcycle engine looks.  Upgrade based on the original design to improve performance and reliability represents the most significant feature of motorcycles.
.Reliable structure: Designed with OHV (overhead valve) bottom camshaft top rod air distribution structure, two cylinder cylinders are at a 45° angle, each cylinder has two valves,.The rocker arm and the connecting rod cooperate more smoothly, and the independent intake and exhaust design to ensure more accurate switch.
.Fine Processing: The body is manufactured with aluminum CNC precision processing, and the two copper exhaust elbows are more distinctive. The surface of the cylinder block is anodized and the rocker cover is chrome-plated. The engine will remain bright and clean for a long time, which makes a visually pleasing artwork
.Stable Performance: The crankshaft runs smoothly with large-area heat sink featuring ideal air-cooling effect, ensuring prolonged yet stable performance. The sensitive single carburetor throttle response  and the normal speed range of 2000-8000rpm are our highlights
.Widely Application: Whether it is used as a static model collection or started and applied to an RC model car, it is not inferior at all. The model reserves many upgradeable parts, giving players a lot of room for hands-on modification. At the same time, it is also an excellent personalized gift for model engine lovers
.Note: The engine comes with a spark plug and CDI igniter, does not include the fixed storage base of the engine and the electric starting device, please contact us if you have any requirements. Please operate the engine according to the instructions in the manual to avoid damage to the engine due to improper operation. Suitable age: 14 years old and up

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.

Almost as awesome.

There are some things to be said about this awesome little engine. It is awesome. I do love it. But when it comes out of the factory with timing thats not correct. Valves that arent doing what they are supposed to. And carbs that wont tune properly and blow back smoke. And a manual that is not helpful at all. it becomes just a desk ornament. It now feels like they just assembled it. And sent it out barley able to run. I get needing to tinker to make it perfect. But i should not have to disassemble the engine just to get it correct, when it should have been correct out of the box. I wish it was less mass producing and more quality care for these engines. Its so close to being perfect. So close.

I wanted to own a model engine for quite some time now, but I either couldn't afford it or wasn't satisfied with what I saw and COULD HEAR in videos.
So the VT9 is my first one and I love it! Yes, it's all about the sound, the smell and the vibration!
It was quite challenging to find the right settings for a slow idle speed. But I think an engine lover will enjoy that. What surprised me though was that it started on the first try after unboxing.

Building a chopper

Motor looks beautiful I am building a frame got tires making rims, spokes will be fun. Motor is mounted, will be mounted on a wood base when done to show off how it runs. Desk display for all to see. 3D printing fenders hand Making gas tank out of metal.

Awsome little motor

Absolute cracker of a motor well made starts easier enough and sounds great. I bought tbe black one and now got the air filter on it. If your into engines or scale models then this is the place to buy from. Will be making a frame for it this is just a mock up.
