Tips: Are brushless motors with lower KV better?
The higher the KV, the greater the resistance. Higher resistance results in a slower motor. This means that the rotational rating is inversely proportional to the amount of electricity produced by the motor. Therefore, motors with lower KV tend to be faster.
