Frequently Asked Questions

What is the difference between sensored and sensorless brushless motors?

Sensored motors have internal sensors that provide feedback to the ESC, allowing smooth startup and precise low-speed control without cogging. Sensorless motors rely on back-EMF to detect rotor position, which can cause stuttering at low speeds but are generally simpler and cheaper. Sensored is better for crawling and racing, while sensorless is fine for bashing and speed runs.

How do I choose the right KV rating for my RC car?

KV rating indicates RPM per volt. Higher KV (e.g., 5400KV) gives more speed but less torque, suitable for lightweight on-road cars. Lower KV (e.g., 2000KV) provides more torque for heavier off-road vehicles and crawlers. Match the KV to your car’s weight, gearing, and intended use. For 1/10 scale, 3000-4000KV is a common all-around range.

Can I use a brushless motor with my existing brushed ESC?

No, brushless motors require a brushless ESC that can handle the motor’s voltage and current. Brushed ESCs are not compatible. You must upgrade both the motor and ESC together. Some brushless ESCs can run both sensored and sensorless motors, but check compatibility.

Do I need to gear down when upgrading to a brushless motor?

Often yes. Brushless motors produce more power and can overheat if geared too high. Start with a lower pinion gear and monitor motor temperature. Many manufacturers provide gearing recommendations. It is better to start conservative and adjust based on heat and performance.

How do I maintain a brushless RC motor?

Keep the motor clean by blowing out dust and debris after runs. Check bearings for smooth rotation and replace if gritty. Avoid submerging in water unless the motor is rated waterproof. Reapply light oil to bearings periodically if recommended by the manufacturer. Also, ensure proper gearing to prevent overheating.
