CISON FG-VT9 9 cc V-twin Motorcycle RC Engine

CISON FG-VT9 9 cc V-twin V2 Engine Air-Cooled Motorcycle RC Gasoline Engine.

Latest Version!

Key improvements in the new version (FG-18VTP):

• Increased displacement: Originally 9 cm³, later expanded to 15.7 cm³, and now to 18.2 cm³ for more power and smoother operation.
• Larger bore: Increased from 16.67 mm to 20 mm for improved combustion.
• Extended stroke: Lengthened from 21 mm to 29 mm for more torque and better overall performance.
• Improved exhaust system: The previous stainless steel exhaust pipe was replaced by a 3D-printed exhaust system, which is lighter and more elegant.

A V2 engine, also known as a V-twin, is a two-cylinder engine in which the cylinders form a “V”. It is also referred to as a Panhead engine, as it is an overhead-valve Harley-Davidson motorcycle engine, named because the rocker covers resemble 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 a 90-degree angle, which is called an L-twin. These engines are primarily used for their compact size, high power-to-displacement ratio, and low power-to-torque ratio. Since the late 1880s, V2 engines have also been used in motorcycles and some small cars. The most widely used V-twin engines are the 45° Harley-Davidson motorcycles, most of which are air-cooled, but there are also water-jacketed engines and the water-cooled VRod engine. Vibrations are often associated with the myth of the V-twin, but are an unfortunate side effect of the most popular design. Harley placed the two cylinders at a 45-degree angle to each other on a common crankcase so the engine would fit into a bicycle-like frame originally intended for a single-cylinder engine. Unfortunately, a 45-degree V-angle has a distinct vibration signature. Most engine experts agree that the soul of the V-twin lies in the vibration and shaking of the engine compartment. There is no doubt that most engine connoisseurs believe the soul of the V-twin lies in the trembling and quaking of the engine compartment.

Scope of delivery:

• Engine only: Engine fully assembled with ignition system and exhaust pipes
• Engine with wooden base: Engine fully assembled on a wooden base with ignition system, exhaust pipes, fuel tank, and electronic accessories

Impressive attention to detail:
The authentic rocker cover on the classic cylinder head and the gearbox cover allow the model to restore the original charm and come closer to a real motorcycle engine, depicting the most notable features of a motorcycle from that era.

Compatible with RC vehicles:
Features a larger cylinder diameter and a longer stroke for better displacement, along with stronger connecting rods to provide excellent torque protection when installed on vehicles.

Reliable construction:
Utilizes an OHV valve mechanism, a 45° angle between two cylinders, a realistic hemispherical combustion chamber, an intake rocker arm with a V-shaped angle, and a removable rocker cover chamber for easier observation and adjustment of the engine.

Reliable and high performance:
Equipped with a large-area heat sink for incredible air-cooling effects, the engine is able to operate stably by maintaining low speeds, and supports the use of various fuels for smoother combustion thanks to the optimized carburetor.
