Hobbywing Skywalker 20A 4S V2 Mini Speed Control

The Hobbywing Skywalker 20A 4S V2 Mini Speed Control (HW30205201) is a compact, brushless ESC built around a high-performance 32-bit microprocessor running at up to 96MHz. Featuring DEO (Driving Efficiency Optimisation) technology, it delivers crisp throttle response, improved efficiency and lower operating temperatures. With 2–4S LiPo support, a dependable 5V/2A switch-mode BEC and a lightweight, small footprint, it integrates easily into space-conscious builds. Programming can be performed via transmitter or by connecting the separate programming cable to a compatible LED Program Box.

Key Features

• 32-bit microprocessor (up to 96MHz) for excellent motor compatibility.
• DEO (Driving Efficiency Optimisation) enhances throttle response and efficiency while reducing ESC temperature.
• Separate programming cable enables LED Program Box access for convenient setup.
• Normal/Reverse brake modes help shorten landing distance for the aircraft.
• Search mode emits alarm beeps to locate an aircraft in complex environments.
• Comprehensive protection: start-up, ESC thermal, capacitor thermal, over-current, over-load, abnormal input voltage and throttle signal loss.
