TOMCAT SKYCLAW 20 AMP ESC FOR 330/450 CLASS MULTI-ROTOR BL ESC OptoAdopt high frequency MCU (up to 50MHz) as the main control chip, the computing speed of the ESC is faster and the response speed of the throttle is dramatically improved. Applying the synchronous rectifier technology, it can increase the ESC efficiency (significantly reduce the ESC temperature), improve the throttle linearity, and speed up the deceleration response of the motor. The ESCs only have one programmable item (Timing), it is very simple to
