• Compact and lightweight – optimized for installations with limited space and weight constraints
• Telemetry integration – enables real-time monitoring of voltage, temperature, and receiver battery status
• AUX wire functionality – supports RPM output, governor gain input, and arming lockout safety
• Data logging capability – records flight metrics for post-flight analysis and performance tuning
• USB and mobile programmability – full access to configuration settings and firmware updates

What makes the Castle P-CC11900 suitable for high-performance aircraft?

The Castle P-CC11900 with 50.4V max voltage, 116g weight with wires, and 76.2mm length is engineered to meet the demands of high-output flight systems. Its 120A continuous current rating ensures consistent power delivery during extended climbs, rapid throttle transitions, and sustained high-load conditions. The compact dimensions and reduced weight make it ideal for installations where space is limited and every gram counts. Whether used in precision helis or 12S fixed-wing aircraft, the Phoenix Edge Lite 120HV supports responsive control and efficient power management without compromising structural integrity or flight dynamics.

How does telemetry improve flight safety and system awareness?

Telemetry transforms the Castle P-CC11900 Phoenix Edge Lite 120HV ESC into a real-time diagnostic tool. By integrating with Castle Telemetry Link modules for S.BUS2 and X-BUS systems, pilots gain access to live data on ESC temperature, input voltage, and receiver battery status. Audible alerts and LED flash patterns provide immediate feedback on system anomalies such as over-temperature, excessive load, or locked head speed. These alerts help prevent mid-flight failures and allow pilots to make informed decisions based on actual system conditions, enhancing both safety and performance.

What functions does the AUX wire unlock?

The white AUX wire included with the Phoenix Edge Lite 120HV ESC with RPM output, governor gain input, and arming lockout key adds a layer of programmable control. It can be configured to adjust helicopter governor gain mid-flight, output RPM data to compatible gyros, or act as an audible beacon after an unexpected landing. Additionally, the AUX wire supports arming lockout functionality, preventing motor activation until a designated receiver channel exceeds 50% signal. This feature is especially valuable during setup, transport, or maintenance, where accidental motor engagement poses a safety risk.

How does data logging support performance optimization?

The Castle P-CC11900 programmable ESC with Castle Link USB access and reduced weight includes onboard data logging that captures key flight metrics such as RPM, voltage, current draw, and system alerts. These logs can be reviewed using Castle Link software to identify inefficiencies, diagnose faults, and refine throttle curves or governor settings. For pilots focused on continuous improvement, data logging provides actionable insights that support iterative tuning and precision calibration across flight cycles. This capability is especially useful in competitive or experimental builds where performance margins are critical.

How can users configure the Castle P-CC11900?

Programming the Castle ESC for 3S–12S LiPo setups with no internal BEC and full telemetry compatibility is straightforward and flexible. Users can access the full configuration suite via the Castle Link USB adapter (included via coupon) and Castle Link Windows software. Mobile programming is supported through the Castle Link iOS App and B-Link Bluetooth Adapter. Settings such as throttle response, voltage cutoffs, and AUX behavior can be adjusted to match specific aircraft requirements. Manual programming via transmitter stick is also available for basic field adjustments. Firmware updates are provided free of charge, ensuring long-term compatibility and feature expansion.

Why is the Phoenix Edge Lite 120HV ESC built without an internal BEC?

Excluding an internal BEC allows the Castle P-CC11900 Phoenix Edge Lite 120HV ESC to support external voltage regulation systems tailored to specific receiver and servo configurations. This design reduces onboard complexity and enables the use of high-voltage components that operate outside standard BEC ranges. For advanced aircraft builds, external regulation offers cleaner power distribution and greater flexibility in component selection. The absence of a BEC also contributes to the ESC’s reduced weight and compact form factor, aligning with the needs of performance-focused installations.

Is the Castle P-CC11900 the best choice for demanding flight environments?

In contexts where sustained output, responsive control, and intelligent system monitoring are essential, the Castle P-CC11900 Phoenix Edge Lite 120HV ESC stands out as a reliable and configurable solution. Its high-current rating, telemetry integration, and programmable safety features make it suitable for aggressive flight profiles and precision maneuvers. The compact design supports installations with strict space and weight constraints, while the data logging and AUX functionality provide tools for both safety and performance optimization. For pilots seeking a robust ESC that adapts to evolving flight demands, the Phoenix Edge Lite 120HV offers a compelling balance of power and control.
