Electric Speed Controller for RC Drone

The 4 in 1 45A ESC for RC Drone features a high-performance 45A electronic speed controller (ESC) with double hole spacing designed for FPV RC Drones. The main control chip is the EMF8BB21F16G, operating at a frequency of up to 48MHz with a 3-in-1 IC driver. The high-end PCB production process uses metalized cladding on the pads to prevent them from falling off during use. The thick 3-ounce, six-layer copper design greatly reduces heat, resulting in higher efficiency.

Integrating four high-performance 45A ESCs, the 4-in-1 unit is compact, with a size similar to a standard racing traverser. This design simplifies installation and wiring, making it well-suited for racing-class traversers. The ESC utilizes the BLHeli-S firmware, providing powerful performance and rich functions. It supports various methods for setting ESC parameters or upgrading the firmware, such as through the throttle cable, using other development boards, or employing Cleanflight or Betaflight firmware.

The PWM hardware motor drive delivers low noise and a more responsive throttle. Damped Light technology and regenerative braking function enhance motor deceleration sensitivity and control accuracy. The active continuation technology allows for battery power recovery, prolonging navigation duration.

In addition to the standard PWM throttle mode, the ESC supports Oneshot125, Oneshot42, and Multshot ultra-high-speed throttle, as well as the latest Dshot 150, 300, and 600 digital throttle protocols for improved anti-interference and quicker response. The input and output lines use soft, silicone wires that are highly temperature-resistant and easy to solder.

The 4-in-1 45A ESC for RC Drone weighs approximately 46g (1.6oz) and is made of electronic components. It is available in a range of colors. The rich functionality, compact design, and advanced features make this ESC an excellent choice for FPV RC Drone enthusiasts, particularly those engaged in racing activities.
