U8 LITE 85kv

Home » U8 LITE 85kv

The “U8 LITE 85KV” is a specific type of brushless motor designed for heavy-lift applications, such as large multirotor drones, aerial photography platforms, industrial drones, or other unmanned aerial vehicles (UAVs) that require high torque and efficiency. Here’s a breakdown of its key features and characteristics:

1. Brand and Model:

  • U8 LITE: Likely the brand and model name of the motor.

2. Brushless Motor:

  • Efficiency: Brushless motors are known for their efficiency and reliability due to their design, which eliminates the need for brushes and commutators. They offer high power-to-weight ratios and longer lifespans compared to brushed motors.
  • Durability: Brushless motors are durable and require minimal maintenance, making them suitable for continuous heavy-duty use in drones and other applications.

3. Configuration:

  • 85KV: Indicates the motor’s KV rating, representing the RPM (Revolutions Per Minute) the motor will spin per volt applied. In this case, the motor spins at 85 RPM per volt.
  • Low KV: Lower KV motors are designed for high torque applications, making them suitable for heavy-lift drones or those requiring smooth and stable flight characteristics.

4. Applications:

  • Heavy-Lift Drones: The U8 LITE 85KV motor is designed for heavy-lift applications where high torque is required to lift heavy payloads such as professional cameras, LiDAR sensors, or other specialized equipment.
  • Agriculture and Mapping: These motors are commonly used in agricultural drones or mapping drones for carrying specialized sensors and equipment for crop monitoring, surveying, or mapping purposes.

5. Features:

  • High Torque: The low KV rating indicates high torque output, enabling the motor to generate sufficient thrust to lift heavy payloads with ease.
  • Stability: Low KV motors provide smoother and more stable flight characteristics, which is crucial for capturing steady aerial footage or conducting precise aerial surveys.

6. Compatibility:

  • Propeller Size: Choose propellers compatible with the motor’s KV rating and torque output. Larger propellers are typically used with low KV motors to maximize efficiency and thrust.
  • ESC (Electronic Speed Controller): Ensure the ESC can handle the motor’s current draw and voltage requirements. Match the ESC’s specifications with the motor’s KV rating and power output.


The U8 LITE 85KV motor is a specialized brushless motor designed for heavy-lift applications in drones and UAVs. With its high torque output and efficiency, it is suitable for lifting heavy payloads and maintaining stable flight characteristics. Understanding its KV rating, torque output, and compatibility with propellers and ESCs is essential for integrating it into a heavy-lift drone build and achieving optimal performance.
