Features:This is the best 10A ESC for multirotorThis hardware, together with SimonK firmware, provides the ideal solution for multi-core applicationsHighest performance 100% N-FET design. Highest accuracy thanks to the Crystal Oscillator (temperature does not affect the PWM operating range like other cheap ESC). No low voltage cut-off because every cut-off in the multirotor = crash. Not above the cut-off temperature, because every cut-off in the multirotor = crash. Super high refresh rate, without buffering the input signal, resulting in more than 490Hz response percentage. Motor frequency 16 KHz, which gives the fastest motor response, and quietest operation as well (no 8 KHz squeak). Very simple, reliable operation! There is nothing to program beyond the throttle range. Specifications:Max cont. Current: 10A Peak Current: 20A (10 s)Voltage: 2-3 SBEC: 5 V/3AUweight (SimonK): Before you buy them, you should familiarize yourself with the somewhat experimental nature of SimonK firmware. This software pushes the motor response to the limit, so there can be combinations of motor and support, that won't work. Package List:1 x Simonk 10A Brushless ESC
