Category: (ESC) Drone Speed Controller

XRotor Micro 30A BLHeli_S OneShot125 ESC is a high-quality multirotor speed controller specially designed for drone racing. They have a broad range of programming features combined with a super smooth throttle range.

Readytosky XRotor Micro ESC series speed controllers come with BLHeli_S firmware with Oneshot125 protocol and support all BLHeli functions like ESC programming. Firmware can be upgraded via the throttle control signal cable. Twisted pair cable to throttle which reduces interference and crosstalk.

Small lightweight and ease of installation make this feature-packed ESC’s a great addition to your 130~280mm racing drone frame.

BLHeli Firmware Ready

Users can flash or upgrade the BLHeli firmware via the signal cable (on ESCs); and program 4 ESCs simultaneously after connecting their flight controller; to the BLHeli Suite software if the flight controller uses the CleanFlight firmware.

Quality Components

The use of EMF8BB21F16G MCU (with the operating frequency of up to 48MHz),  American Fairchild MOSFETs, the imported 3-in-1 drive IC and quality ceramic capacitors, 3-ounce copper and 4 layers of PCBs guarantees less heat, higher efficiency, and more rapid response.

Hardware Generated PWM & Damped Light Mode

The ESC firmware uses hardware generated motor PWM for smooth throttle response and silent operation. Damped light does regenerative braking, causing very fast motor retardation, and it inherently also does active freewheeling.
