Hobbywing XRotor Pro 40A 3-6S Multirotor ESC

The Hobbywing XRotor Pro 40A is a single brushless ESC for 3–6S multirotors, sized by Hobbywing for 550-class quadcopters. It is an OPTO design with no BEC, which keeps the flight controller isolated from ESC switching noise.

Key features

• 40 A continuous and 60 A peak (10 s)
• Multirotor-specific core program for fast throttle response, with adaptive defaults including automatic timing
• DEO (Driving Efficiency Optimisation) improves throttle linearity and efficiency, and can be switched on or off
• Twisted-pair throttle cable reduces signal crosstalk; accepts throttle refresh rates up to 621 Hz
• Supports throttle range calibration, stick programming and timing adjustment

Specifications

• Continuous / peak current: 40 A / 60 A (10 s)
• Battery: 3–6S LiPo
• BEC: none (OPTO)
• Power leads: 16AWG
• Motor connectors: 3.5 mm gold bullet
• Signal cable: 560 mm, twisted pair
• Application: 550-class multirotors

With no BEC on board, power the flight controller from a PDB or a separate regulator. One ESC drives one motor, so order one per arm.
