The Sidewinder Micro 2 ESC boasts updated circuitry and added functionalities. Castle engineers are committed to taking full advantage of advancements in component quality and continuous improvements in software design. As a result, we are thrilled to introduce the Sidewinder Micro 2. The Sidewinder Micro 2 is perfect for 1/18th scale 2WD vehicles and smaller 4WD (up to 2 lbs.) such as the Team Associated RC18B2 or Dromida SC4 SCT. Whether you are converting to a brushless setup or simply needing more power than your current brushless power system is putting out, there is a Sidewinder Micro 2 combo to fit your needs. The Castle 20mm 0808 Brushless Motors are a perfect companion to the Sidewinder Micro 2 and are available in 4100Kv, 5300Kv, or 8200Kv packages.

The included 0808 series 4100Kv motor is suitable for on-road and off-road applications running up to 3S LiPo and weighing in at up to 2.5lbs. Using the same 4 pole technology found in the larger Castle motors, the 0808 series provides the increased efficiency and torque 4 pole motors are known for.

Sidewinder Micro 2 Features:

  • Improved BEC Functionality - Now adjustable: 5.5V or 7.5V
  • Improved Audible Alerts - The ability to diagnose and resolve problems in the field are made easy as this ESC will communicate with audible tones when certain conditions are present. Alerts are present for start fail, voltage cutoff, radio glitch, over-temperature, over-current and excessive load detections.
  • Improved Startup - Updated circuitry and refined software makes for ultra-smooth starts!
  • Link Live functionality added - Link Live is a way for the controller to communicate power system information to an external device. This feature, when enabled, will allow users to experience real-time telemetry data such as battery voltage, ESC temperature, motor power output and battery ripple. Compatibility with the S.BUS® T4PX transmitter is coming soon (Requires purchase of Castle S.BUS2 Telemetry Link)
  • Transmitter Programming - Manual programming settings include Brake/Reverse Type, Voltage Cutoff, Brake Amount, Drag Brake and Motor Type.
  • Castle Link Programming - With the purchase of Castle Link USB device, you will have access to the full programming suite of adjustable settings that tune and tweak your vehicle to your preferences, resulting in an incredible driving experience!
