Simonk 30AMP SimonK Firmware Brushless ESC

Simonk 30AMP SimonK Firmware Brushless ESC w/ 3A 5V BEC For DJI F450 Align TREX 250 450 RC Multicopter Qudcopter Helicopter ESC.

Features:
30A ESC for multirotor.
This hardware, with the SimonK firmware, gives you the perfect solution for multirotor use.
Highest efficiency 100% N-FET design.
No low voltage cutoff, because any cutoff in a multirotor = crash.
No over temp cutoff, because any cutoff in a multirotor = crash.
Super high refresh rate, no buffering of the input signal, resulting in more than 490Hz response rate.
16KHz motor frequency, giving fastest response of the motor, and quietest operation as well (no 8KHz squeal).
Super simple, foolproof operation! Nothing to program other than the throttle range.

Note (SimonK): Before you buy these, you should make yourself familiar with the somewhat experimental nature of the SimonK firmware. This software pushes the motor response to the limit, so there may be motor and prop combinations that won't work. Due to the lack of overcurrent/overheat/low voltage sensing (needed for multirotors), it's easier to destroy the ESC and possibly the motor too. I can't tell you what will or won't work, other than the motors I sell that I've personally used, so please consult the main SimonK threads on various forums for more info. Neither I, nor SimonK will be responsible for any damage that may occur, so know and accept the risks before using these. That said, I've personally had fantastic results with this firmware and wouldn't use anything else!
