30A 2-4S 3A 5V ESC speed controller for drones

30A 2-4S 3A 5V ESC speed controller for drones.

Outstanding features of this product:

This simple ESC was designed specifically for 250 - 450 class multirotor drones, providing excellent quality and performance.
The controllers have factory-set parameters ideal for quadcopters, which makes them ready for immediate use.
Thanks to the high accuracy of the quartz oscillator, you do not have to worry about the effect of temperature on the PWM operating range, which sets this ESC apart from cheap alternatives on the market.
It is worth noting that there is no low-voltage cutoff, which minimizes the risk of damaging the model, and no overheating cutoff, which ensures stable ESC operation even in difficult conditions.
In addition, the super-high refresh rate and 16KHz motor frequency mean this controller provides the fastest motor response and runs very quietly.
