Construction & Materials Of FGV-T9
As you have learned about the basic features and specifications of FGV-T9. Now you will learn about its construction and the material of the FGV-T9 engine.
The FG-VT9 engine is made of aluminum. Moreover, its body and frame are CNC-machined.
So, this makes the engine stronger and accurate. Additionally, its surfaces are anodized to protect it. Furthermore, the rocker cover is plated with chrome.

Then, its exhaust elbows are made up of copper. Also, this engine weighs about 1.5 kg. Moreover, it is small in size but very strong. Additionally, all its parts are carefully connected. Finally, this design helps the engine to work smoothly and stably.
Starting / Ignition / Fuel
As you have learned about the construction and material of the FG VT9 Engine. Now, you will learn about Starting / Ignition / Fuel.
The FG-VT9 engine uses a CDI ignition. Moreover, this igniter is connected to the spark plug. Therefore, it helps in the burning of fuel. Also, an electric drill is used to start the engine. So, when the drill turns the crank, it causes combustion.
Then, it is important to mix oil with gasoline. Therefore, the engine runs on gasoline. Additionally, the normal mix ratio is 25:1. So, this mix helps the engine run well. Besides that, the right fuel and ignition help the engine run smoothly. Hence, proper usage ensures a long and safe life.
Performance & Operation
As you have learned about the starting process of FGV-T9. Now you will learn about its performance and operation.
Firstly, the crankshaft inside moves perfectly. Moreover, this makes the engine stable. Therefore, the FG-VT9 engine runs very smoothly. Additionally, the rocker arms fit the cylinder and valves well. So, this allows the valves to open and close at the right time.
Moreover, the air passes through the intake and exhaust easily. Also, when you press the throttle, the engine responds immediately. Furthermore, this helps all the parts fit and work well.

So, the engine runs strong and is reliable. As a result, all these features make RC models fun and close to reality.
Variants / Options & Base / Accessories
As you have learned about the performance and operation of FGV-T9. Now you will learn about its variants, options, and accessories.
Firstly, the FG-VT9 comes in different colors. Therefore, you can choose the color of your pass. For example, Silver or Black colour. Moreover, some kits include the engine and additional parts. Additionally, they have mechanical or wooden base stands.
So, these bases help to display the engine. Additionally, you can also purchase upgrade parts. Furthermore, all the parts fit together. Hence, these options make the engine more fun and useful. As a result, the collectors and hobbyists enjoy these choices.
