Castle Creations Cobra 5 HV 12S Brushless ESC - 50.4V / 20A BEC

Overview

The Castle Creations Cobra 5 HV (010-0178-00) is a high-voltage, high-performance brushless electronic speed controller designed for the most extreme RC power systems. Supporting up to 12S LiPo (50.4V), the Cobra 5 HV delivers exceptional power handling, refined throttle control, and outstanding thermal stability under heavy load.

Engineered for large-scale vehicles, marine builds, and custom high-voltage applications, the Cobra 5 HV uses Castle's advanced control architecture to deliver smooth acceleration and predictable braking even at the limits of electric RC performance.

A powerful onboard 20A peak BEC easily supports high-torque digital servos, removing the need for a separate BEC and simplifying complex installs.
