About the HPro ESC
Smart Control, High Current Handling, and Advanced Protection
At its core, the HPro 125A uses a high-performance 32-bit G4 processor running at 170MHz, delivering ultra-fast signal processing and precision throttle response. The ESC incorporates next-gen MOSFETs for reduced heat and improved current endurance, while a large heat-dissipating case and temperature-controlled fan ensure efficient cooling. A built-in self-check system verifies power and signal conditions at startup, and advanced features like a helicopter governor, stall landing protection, and multi-system telemetry support maximize flight stability. The ESC is also customizable via phone apps or transmitter interfaces and includes colorful LED status lights for intuitive monitoring. With its wide compatibility and multiple safety protocols, the HPro 125A is built for high-performance flight.
