INFORMATION
A transmitter is a portable device that connects you to your RC car or truck. Its functionality is determined by the number of channels it can control and the tuning controls it has. The primary purpose of the transmitter is to communicate with the receiver on your RC. While most transmitters require AA batteries, some models offer rechargeable battery packs as an alternative.
The receivers on your RC car or truck are responsible for communicating with your transmitter through the antenna. The labeled slots on the receiver allow you to control specific items using your binded transmitter. Your Steering Servo and Electronic Speed Controller (ESC) usually occupy positions 1 and 2 on the receiver. All accessories that communicate or receive power through the receiver are connected via a physical wire plug-in.
In the world of RC, servos have multiple applications, but in this case, we will concentrate on their role in steering your vehicle. Servos are available in different types that affect their speed, durability, strength, and size. It's important to note that not all servos are suitable for every car or truck, and they usually occupy the first position on your receiver.
The Electronic Speed Controller, also known as ESC, provides the On/Off switch for your RC through a switch or button. It's crucial to consider your motor and battery type when selecting an ESC. Before choosing an ESC, identify the battery types you want to use and ensure that the ESC has the appropriate connection for the motor type you plan to use.
You have the option to choose between Brushed or Brushless motors for your RC vehicle. While both can make your vehicle move, they have different ways of doing so that may affect your decision based on your build. Brushless motors are more efficient and powerful, but if you expect mud, dirt, sand, and rocks to interfere, a sealed brushless motor may be a better long-term option. Brushed motors offer better linear acceleration for lower power applications and are often used in "Spec" class RC racing to limit motor tuning and speed differentials.
When it comes to batteries for your device, the most common options are NiMH and Li-po. However, it's important to check which type of battery your ESC can handle. Some ESC’s are compatible with both types of batteries usually identified by moving the binding post on your ESC for the selected battery type. Note the battery size and capacity… The size is often represented as “Cells” or “2S” for example typical NiMH battery has 6 Cells and a typical Li-po battery is represented as 2S, 3S and up. The Capacity is represented as a number followed by milli ampere hour as “mAh” for example 2000mAh. In short as a quick reference to help you remember: Size=Power / Capacity=Runtime.
A charger is essential for recharging electric batteries, but the charging capabilities depend on the charger's complexity and wattage. It's crucial to consider the type of battery (NiMH or Li-po) because they require different charging methods. Once you've selected a charger for your battery type, you can determine the wattage output and charging quantity. Some chargers can handle multiple battery types and charge four batteries simultaneously at 75 watts each. Take your time to find the best charger for your RC.
