20AMP 20A SimonK Firmware Brushless ESC w/ 3A 5V BEC for RC Quad Multi Copter

Features:

• This is THE BEST 20A ESC for multirotor
• This hardware, with the SimonK firmware, gives you the perfect solution for multirotor use
• Highest efficiency 100% N-FET design.
• Highest accuracy with Crystal Oscillator (temperature won't affect the PWM operating range like other cheap ESC's).
• 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.

Specifications:

• Max cont.current: 20A
• Peak current: 30A (10s)

• Net weight: 23 g
• Package weight:33 g

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.
