SimonK Firmware ESCs are quality speed controllers and designed for simple installation and easy setup. These ESCs have proven to offer excellent performance in multi-rotor applications.

These ESC's features a very smooth yet linear throttle response, without sacrificing a rapid, crisp, response to any throttle input. Super fast Refresh Rate up to 600Hz make these a very smooth controller. That is to say support PWM input rates up to 600Hz for great response on your quad-copter. Fashion design and high quality with best performance but sells at very reasonable price.

Features:

• Extremely low internal resistance
• Super smooth and accurate throttle linearity
• Safety thermal over-load protection
• Auto throttle shut down in signal loss situation
• Supports high RPM motors
• Power arming protection (prevents the motor from accidentally running when switched ON)
• Use new generation of the MOSFETs to make sure the ESC with low heating and more reliability
