Dualsky Summit 220XHV 220A OPTO Brushless ESC
The
The Dualsky Summit 220XHV is a high-voltage, 220-amp brushless electronic speed controller engineered for giant-scale RC airplanes, powerful electric conversions, large aerobatic models, and demanding UAV applications.
Supporting 5S–14S LiPo batteries, the Summit 220XHV provides the current capacity required for high-output motors such as the Dualsky GA8000 series. Its 32-bit control system, low-resistance MOSFETs, CNC-machined aluminum housing, cooling fan, telemetry capability, and extensive programming options provide precise control for demanding electric power systems.
Important—No BEC: The Summit 220XHV is an OPTO speed controller and does not supply power to the receiver or servos. A separate receiver battery, regulated power system, or suitable external UBEC is required.
Key Features
- 220A Continuous Current Rating: Designed for giant-scale electric aircraft and other high-current brushless power systems.
- 5S–14S LiPo Compatibility: Supports battery systems from 18.5V through 51.8V nominal voltage.
- Up to 290A Peak Current: Provides additional short-duration capacity for acceleration and demanding flight loads when properly cooled.
- 32-Bit ARM Control System: High-speed motor-control processing with drive frequencies up to 48 MHz.
- Low-Resistance MOSFETs: Uses high-performance TOLL-package N-channel MOSFETs for efficient high-current operation.
- CNC Aluminum Housing: Full-metal housing helps protect the electronics and transfer heat away from critical components.
- Cooling Fan: Fan-assisted cooling helps manage temperatures in high-power installations.
- USB-C Programming: Integrated USB Type-C connection supports programming and firmware updates.
- Telemetry Support: Supports multiple telemetry protocols and automatic protocol recognition when used with the appropriate connection or adapter.
- Multiple Motor Directions: Supports normal, reverse, and bidirectional motor operation.
- Sine-Wave Mode: Optional sine modulation can provide smoother and more efficient motor operation in compatible applications.
- Regenerative Braking: Supports regenerative braking and active freewheeling.
- Programmable Protection: Includes configurable temperature, current, low-voltage, low-RPM power, and demagnetization protection.
- S.BUS Input Support: The selected S.BUS channel can be configured through the compatible Summit X application.

Installation Notes
- A separate receiver battery, power-distribution system, or external UBEC is required.
- Use connectors, wiring, batteries, and motors rated for the expected current and voltage.
- Install the ESC where cooling air can reach the aluminum housing and fan.
- Keep power wiring as short as practical and secure all high-current connections.
- Confirm motor timing, PWM frequency, current protection, and low-voltage settings before operation.
- Remove the propeller before programming, updating firmware, or testing the throttle system.
