Features

• 300KV brushless motor is designed for long-flight time multi-rotors. These motors can produce enough torque at low RPM and work at peak efficiency during flight.
• With the guarantee of strength, the caps of brushless motors are highly hollow-cutted to save weight, so these motors can reach the maximum thrust-to-weight ratio and gain more flight time.
• The brushless drone motor series uses a patented Stepped and knurled design that not only efficiently prevents motors from getting loose, but also reduces the probability of malfunction and unstable output power.

Tips: How to select the right multi-rotor drone motor?

• Motor: The motor of the multi-rotor drone should consider the weight of the entire drone, and the maximum pulling force of the motor should be selected according to the weight of the entire drone.
• KV: KV value of the multi-rotor drone motor is the rate of change of the motor's idle speed per minute under 1V voltage. For a motor of the same power, the higher the KV value, the faster the speed change per unit voltage, which means the faster the response speed that can be achieved.
• Size: The size of the multi-rotor UAV motor, according to the KV value to select a number of suitable motors, then we need to see whether the motor can be installed on the rack, that is, we need to consider the size of the motor.
