Hobbywing Skywalker 120A 8S V2 Speed Control

The Hobbywing Skywalker 120A 8S V2 Speed Control (HW30205450) is a brushless ESC designed for fixed‑wing RC aircraft, delivering 120A continuous current with support for 3–8S LiPo setups. A 32‑bit ARM M0 processor running up to 120MHz and Hobbywing’s DEO technology help provide crisp throttle response while keeping temperatures in check. An adjustable high‑current switch‑mode BEC offers 5V, 6V, 7.4V or 8.4V output to suit a wide range of servos and receivers.

Pilots benefit from programmable normal/reverse brake modes to shorten landing distance, plus protective features including low‑voltage cutoff, thermal protection and signal‑loss fail‑safe. A built‑in search mode can aid locating a downed model with audible beeps. Setup can be carried out via your transmitter or the optional LED Program Box (HW30501003).
