Brushless Cars

BRUSHLESS CARS

Radio Control Electric Powered Cars and Trucks are very popular. Electric modeling is an excellent way to get in to the hobby. Often times a brushed electric motor may come in a RTR vehicle. After a while the hobby bug bites and it bites hard. Soon you will be thinking of going faster or adding more power. When this time comes, it is time to upgrade to brushless.

Choosing a brushless power system is not as easy as it sounds. There are often many items that must be selected carefully. For example, motor KV, motor size, cell count, ESC ratings, LiPo Capacity, C rating, ect.

View the following link by clicking the photo below to use the Radio Control Car/Truck Setup Calculator. Determine which motor, cell count and ESC will work best for you!

If your model already contains a brushless setup there are often other things to consider for upgrades. This may include the cell count, or gearing.

Please review the several pages of information. This will increase your odds for a more successful upgrade route, or better your knowledge in certain areas for a Radio Control Car or Truck.

Cell Count

CELL COUNT For details on LiPo batteries, visit the LiPo Page. When building a Car or Truck from a kit or several parts, one of the first selection for your power system should be the cell count. This is important as it sets the basis for how much power you can extract from the system. Of …

Motor

BRUSHLESS MOTOR SELECTION To select the motor best suited for a Radio Control Car or Truck, it is important to know the size of the model and amount of LiPo cells planned to be used. Size of the RC vehicle will determine the size of motor needed to push the weight. For motors this is …

ESC

ESC – ELECTRONIC SPEED CONTROL An ESC regulates the power from the batteries to the motor. It must be properly selected in order to be able to handle the current draw demanded from the motor. It is recommended to choose a high quality ESC. In most cases, once the cell count and motor is selected, …

Operating Temperature

OPERATING TEMPERATURE There are several reasons equipment may heat up, if this is the case here are possible causes. Too hot – greater than 160F/70C. Many times there may be more than one reason for over heated equipment. In this case choose the most logical fix. Motor – Too Hot – Gearing set too tall. …

Gearing

GEARING All electric powered radio control trucks or cars require gearing. Gearing allows the change in RPM to better suit what is needed at the wheels. For example a typical Electric Motor Setups can potentially rev in excess of 30 000 RPM. The wheels however usually rotate at a much smaller rate. The way this …
