Petrol RC Cars:
1. Fuel: Petrol RC cars run on a mixture of petrol and oil, typically in a ratio of 20:1 or 25:1. The fuel can be purchased at petrol stations or hobby stores.
2. Engine: Petrol RC cars use either a two-stroke or four-stroke engine specifically designed to run on petrol. Two-stroke engines require the oil to be mixed with the petrol, while four-stroke engines have a separate oil reservoir.
3. Performance: Petrol RC cars can be very fast and powerful, capable of reaching speeds of up to 50 mph (80 km/h) or even higher. They produce a loud and distinctive exhaust sound similar to small motorcycles or chainsaws.
4. Maintenance: Petrol RC cars require more maintenance compared to nitro or electric cars. The engines need regular maintenance, including cleaning, replacing spark plugs, and adjusting the carburetor.
5. Noise and Emissions: Petrol RC cars are louder and produce more emissions compared to nitro and electric RC cars. This can make them less suitable for use in residential areas or where noise regulations are in place.
Nitro RC Cars:
1. Fuel: Nitro RC cars use a special fuel called nitromethane, which is mixed with methanol and lubricating oil. The nitromethane content in nitro fuel can vary from 5% to 30% or even higher.
2. Engine: Nitro RC cars have a small internal combustion engine specifically designed to run on nitro fuel. These engines are typically faster revving and produce more torque compared to petrol engines.
3. Performance: Nitro RC cars can be very fast, typically reaching speeds of around 40 mph (65 km/h) or higher. They produce a high-pitched sound and a distinctive smell from the exhaust.
4. Maintenance: Nitro RC cars require regular maintenance, including cleaning the engine, replacing glow plugs, and adjusting the carburetor. However, they generally require less maintenance compared to petrol RC cars.
5. Noise and Emissions: Nitro RC cars are fairly loud, but they produce fewer emissions compared to petrol RC cars. They are still not suitable for use in quiet residential areas due to the noise they produce.
In summary, petrol RC cars offer impressive speed and power but require more maintenance and produce more noise and emissions. Nitro RC cars are also fast but tend to be easier to maintain and produce fewer emissions compared to petrol RC cars. Both types of cars require some mechanical knowledge and experience to operate and maintain properly.
