DualSky SUMMIT 100HV Speed Controller (SUMMIT series brushless speed controller)

DualSky SUMMIT 100HV — a high-performance brushless speed controller designed for precision F3A models and aggressive aerobatic flight. Its robust CNC-machined aluminum casing combines reliability with excellent heat dissipation, ensuring stable operation under the most demanding conditions.

This ESC supports power input from 4S to 14S LiPo (14.8–51.8V) and is rated for 100A continuous current with a short-term peak current of up to 120A. Its low internal resistance — 1.7 mOhm — reduces heat loss and increases overall system efficiency. The controller comes without a built-in BEC (OPTO option), making it ideal for configurations with external power for the receiver and autopilot.

Key features of the device include: passive cooling via a large aluminum heatsink, internal and external LED status indicators, an anti-spark system for safe battery connection, and a full suite of protections — against overheating, undervoltage, and excessive torque reaction. Automatic setup along with presets simplify programming, while the adjustable braking system allows fine-tuning of motor behavior for specific models and flight styles.

The DualSky SUMMIT 100HV is an optimal choice for pilots who require high current throughput, operational stability, and a full suite of protections in a compact, well-cooled package. The absence of a built-in BEC and the presence of an anti-spark system simplify integration into complex electrical systems with separate power for the control system and receiver. This solution is designed for those who value precise control and reliability during competitions and demonstration flights.
