Hobbywing XRotor 40A OPTO ESC (2-6S)

The Hobbywing XRotor 40A is a dedicated multicopter electronic speed controller built for stability, efficiency, and heavy-lift reliability. Ideal for 450 to 650-sized custom builds, aerial photography drones, and agricultural platforms, it delivers a steady 40 amps on up to 6S power with exceptional heat dissipation.

Key features

• Dedicated multi-rotor firmware for crisp, immediate throttle response

• Twisted-pair throttle signal cable to minimise crosstalk and interference

• Auto-timing adjustments ensure plug-and-play compatibility with a wide range of brushless motors

• Ultra-low internal resistance for cooler sustained operation

Specifications

• Continuous Current: 40A

• Burst Current: 60A (10 seconds)

• Input Voltage: 2-6S LiPo

• BEC: None (OPTO)

• Power Wires: 16 AWG

• Weight: 26 g

• Dimensions: 68 x 25 x 8.7 mm

As an OPTO ESC, this unit does not step down voltage to supply power to your receiver or flight controller. You will need to route a dedicated standalone 5V BEC or utilise a flight controller with integrated regulators to power your avionics.
