These high-quality HW30A ESCs (Electronic Speed Controllers) are ideal for RC airplanes and drones. They feature a safe power function, throttle calibration function, and low voltage protection mode. The ESCs are also lightweight and compact, making them ideal for small aircraft.

Features:

• Safe power function: Regardless of the throttle stick position, the motor will not start immediately
• Throttle Calibration function: Adapts to different remote throttle travel distances, improves throttle response linearity, with a smooth, delicate feel and excellent speed linear regulation
• Low Voltage Protection Mode: Helps prevent burn out when trying to run a motor below voltage
• Please check the weight and size of the ESC to ensure it will fit inside your Drone or Plane
• Important Notes:
  4S LiPo batteries do not allow use of a BEC (Battery Elimination Circuit)
  Don't use this ESC on any airplane in excess of the specified Voltage or Amperage loads, otherwise it will burn out the ESC.
