An RC car ratio is the speed that a remote-controlled car is able to travel. It is determined by the power of the motor, the size of the wheels, and other elements such as gears, pulleys and other modifications.
The higher the number, the faster your car can go.
The most typical RC car ratios are 1:10, 1:18 and 1:24. A 1:10 ratio means that for every turn of the wheel, the motor will turn 10 times faster.
This means that a car with this ratio will be able to travel faster than one with a lower ratio such as 1:18 or 1:24.
The lower ratios are usually found in beginner level RC cars as they are less powerful and can accelerate slower than higher ratios. Higher ratios are usually found in more advanced RC cars which are capable of reaching higher speeds.
When choosing an RC car for racing or for hobby use, it is important to consider what type of terrain you plan to drive on and how fast you need your car to go in order to be competitive or have fun. If you plan on racing on a flat track then a higher ratio may be beneficial so that you can reach top speeds quickly. However if you plan on driving off-road then a lower ratio may be more suitable as it will provide better torque which will allow you to climb steeper hills and drive through rough terrain.
In conclusion, an RC car ratio determines how fast your remote-controlled vehicle can travel. Different ratios provide different benefits depending on what type of terrain you plan to drive on and how fast you need your vehicle to go. It is important to consider all factors when choosing an RC car ratio in order to get the best performance out of your vehicle.
