HOBBYWING XRotor Pro 40A ESC Built for Stable Multirotor Flight

The HOBBYWING XRotor Pro 40A (Version B) ESC is engineered for serious drone builders who need reliable electronics in a small package. The unit is housed in a sturdy plastic shell and is sized to sit inside a 23mm carbon tube, offering solid protection and a tidy installation.

Smart Timing and Easy Setup

Auto timing adjustment and factory preset parameters reduce setup time and help newcomers get a good tune quickly. The intelligent routines tune motor timing automatically so you can focus on flight rather than fiddly configuration.

Fast Throttle Response for Precise Handling

A dedicated core program gives the XRotor Pro 40A rapid throttle response, helping maintain hover stability and enabling tight manoeuvres in multi-rotor applications where control precision matters.

Driving Efficiency Optimization (DEO) for Smoother Flight

With Driving Efficiency Optimization (DEO) technology onboard, this ESC improves drive efficiency for cleaner, more consistent power delivery across different throttle loads.

Effective Thermal Design for Longer Runs

The ESC uses an aluminum folded fin heat sink plus a heat-conductive slotted layout to move heat away from the electronics, helping keep performance steady during longer flights.

The HOBBYWING XRotor Pro 40A ESC is a practical choice for pilots building 550 class multirotors who want dependable throttle feel and effective cooling in a compact unit.
