Skystars KM65 is a powerful ESC for 5-8" freestyle and long-range drones. The ESC supports 3-6S batteries and current up to 65A, which makes it suitable for motors sizes 2207-2808. The ESC has an aluminum heat sink on it to help dissipate heat better while protecting sensitive components from mechanical damage. It can be connected to the flight controller via a connector, but pads for soldering are also available. The ESC uses a powerful F4 32-bit processor and BlHeli_32 firmware. It supports telemetry, bidirectional DShot and PWM frequency up to 128KHz.
