Brushless 40A 2-4S ESC for Drone

The Brushless 40A 2-4S ESC is specifically designed for quadcopters and multi-rotors, providing faster and more efficient motor speed control for enhanced flight performance compared to other ESCs on the market.

This ESC features a multi-integrated special program, rapid throttle response, and outperforms various open-source software options. The firmware is optimized for disc motors, ensuring excellent compatibility with 2-4S LiPo batteries.

It uses twisted wire for the throttle signal line to minimize crosstalk from the copper transmission signal, resulting in a more stable flight experience. This ESC supports throttle signal refresh rates up to 621Hz and is compatible with a variety of flight controllers (note: throttle signals above 500Hz are considered non-standard).

With ultra-low resistance MOSFETs, this ESC offers robust current capacity. The specialized driver integrated circuit enhances performance and stability beyond what discrete component circuits can achieve. Please note that this ESC does not support firmware flashing.
