ITEM NAME:30 AMP Simonk 30A Brushless ESC firmware w/5V 3A UBEC Quad Multirotor APM2 D6Y8 30 AMP Simonk 30A Brushless ESC firmware w/5V 3A UBEC Quad Multirotor APM2 D6Y8 30A ESC for Multirotor. This hardware, with the Simonk firmware, gives you the perfect solution for multi-rotor use. Highest Efficiency 100% N-FET design. 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. Product descriptions No overtemperature shutdown, because any shutdown in a Multirotor = crash. Super high refresh 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 Recommended to do before a throttle trip debugging method: first ESC / motor / receiver connected to push the throttle to the maximum, then the main power connected to hear the D and then immediately to the throttle to the minimum, and then DD slow Slow push the throttle Does not apply to: brushed motors, motors larger than the 2212 model Specifications:. Max cont.
