Is a separate governor required?

No separate governor is needed; the ESC provides programmable control over motor output which handles speed management for most race use.

Will it handle high-turn motors?

The BL-RS4B supports a wide range of brushless motors. Match motor amp draw to the ESC limits and keep within the 6V-7.4V voltage window.

Can I program it without a PC?

Programming can be done using a compatible handheld programmer or, where supported, a PC tool. Check Yokomo guidance for the exact programming method.

What maintenance does the ESC need?

Keep connectors clean and secure, avoid moisture, and inspect solder joints after heavy use. Regular visual checks prevent most issues.
