Feature: 1. 30A ESC for Multirotor. Highest efficiency 100% N‑FET designs. Reliable in use. 2. This hardware, with the Simonk firmware, gives you the perfect solution for multi‑rotor use. Highest Efficiency 100% N‑FET designs. Highest accuracy with Crystal Oscillator (temperature does not affect the PWM operation area as other cheap WSA). No undervoltage lockout, because everyone in a cutoff Multirotor = crash. 30A ESC for Multirotor. 3. This hardware, with the Simonk firmware, gives you the perfect solution for multi‑rotor use. 4. Highest accuracy with Crystal Oscillator (temperature does not affect the PWM operation area as other cheap WSA). 5. No undervoltage lockout, because everyone in a cutoff Multirotor = crash. Specification: Condition: 100% Brand New Item Type: ESC Material: Electronic Components Color: Red Descriptions: No over temperature shutdown, because any shutdown in a Multirotor = crash. Super high rate, no buffering of the input signal, resulting in more than 490 Hz response rate. 16KHz motor frequency, thereby fastest response of the engine, and silent operation as well (no squeaks 8KHz). Super easy, simple operation. Nothing to program other than the throttle region Specifications: Maximum Continue Current: 30A Maximum Current: 40A (10s) Voltage: 2-3S LiPo BEC: 5V / 3A .
