• Batteries: Commonly use Nickel-Metal Hydride (NiMH) for budget-friendly options or Lithium Polymer (LiPo) for higher performance and longer run times. LiPo batteries require specific chargers and careful handling due to their chemical properties.

Nitro RC Cars

These cars use small internal combustion engines that run on a special blend of methanol, nitromethane, and oil (nitro fuel). They offer a more realistic engine sound and the smell of exhaust, appealing to those who enjoy the mechanical aspect of the hobby.

• Pros: Realistic engine sound, can be refuelled quickly for continuous running, satisfying mechanical experience.
• Cons: Louder, require more maintenance and tuning, produce exhaust fumes, fuel can be expensive.

Gasoline (Petrol) RC Cars

Larger scale RC cars (typically 1/5 scale and above) often use small, two-stroke petrol engines similar to those found in garden equipment. They run on regular unleaded petrol mixed with two-stroke oil.

• Pros: Very long run times, relatively inexpensive fuel, impressive scale size.
• Cons: Very large and heavy, loud, significant exhaust fumes, higher initial cost.

Here's a comparison between electric and nitro RC cars:

Understanding Scale: Size Matters

RC car scales indicate the size of the model relative to its full-sized counterpart. A 1/10 scale car, for example, is one-tenth the size of a real car. Common scales include:

• 1/24 & 1/28 Scale: Very small, often used for indoor racing or micro crawlers. Great for limited spaces.
• 1/18 & 1/16 Scale: Compact, versatile, and often a good balance of size and performance for both indoor and outdoor use.
• 1/10 Scale: The most popular and common scale, offering a vast range of models from touring cars to monster trucks. Ideal for backyard bashing and competitive racing.
• 1/8 Scale: Larger, heavier, and typically more powerful. Common for high-performance buggies, truggies, and monster trucks, especially in nitro and high-end electric variants.
• 1/5 Scale: The largest common scale, these are substantial vehicles often powered by petrol engines. They offer an impressive presence and realistic handling, requiring large open spaces to operate.

The choice of scale impacts everything from the price and performance to the space required for storage and operation.

Getting Started: Kit vs. Ready-To-Run (RTR)

When purchasing an RC car, you'll generally encounter two main options:

• RTR (Ready-To-Run): As the name suggests, these models come fully assembled with all necessary electronics (motor, ESC, servo, radio system) pre-installed. Often, they even include a basic battery and charger. RTRs are perfect for beginners as they allow you to get driving almost immediately after unboxing and charging. Brands like Traxxas excel in this market.
• Kit: A kit provides all the components of the vehicle disassembled, allowing the hobbyist to build the car from the ground up. This option is highly rewarding for those who enjoy the building process, offering a deeper understanding of the car's mechanics. Kits typically do not include electronics, allowing for customisation with high-performance components. Team Losi Racing (TLR) is renowned for its high-quality racing kits.

Key Features and Components

Beyond the basic type and power source, several key features contribute to an RC car's performance and durability.
