Skystars KM65 65A F4 4-in-1 ESC

The Skystars KM65 is a 65A 4-in-1 ESC designed to handle the high current demands of aggressive 5-inch freestyle quads and 7-inch FPV builds. Driven by a 32-bit F4 processor, it ensures precise commutation and supports high PWM frequencies for highly responsive motor control.

Key features

• F4 MCU enables high-frequency PWM switching (up to 128kHz) for ultra-smooth throttle curves.
• Sustains 65A continuous current per channel to effortlessly drive large-stator motors.
• Factory-flashed with BLHeli_32 firmware to support advanced motor timing and full ESC telemetry output.

Specifications

• MCU: F4
• Continuous current: 65A
• Input voltage: 3-6S LiPo
• Firmware: BLHeli_32
• Mounting pattern: 30.5x30.5mm

This ESC uses standard 30.5x30.5mm mounting holes, allowing it to drop cleanly into full-sized drone frames and pair seamlessly with modern F7 or H7 flight controllers.
