Q: What does “KV” mean in brushless motors?

A: “KV” in brushless motors stands for "RPM per Volt," which indicates how many revolutions per minute the motor will spin for each volt of electricity applied, with no load. For example, an 1800KV motor will theoretically spin at 18,000 RPM when powered by 10 volts (1800 × 10). A higher KV rating like this means the brushless motor spins faster but has less torque, which is ideal for lightweight or high-speed RC boats. Conversely, lower KV motors offer more torque and smoother control, making them better suited for heavier boats or those requiring stronger acceleration.
