Hobbywing XRotor Pro 50A 4-6S OPTO Multirotor ESC

The Hobbywing XRotor Pro 50A is a single brushless ESC for 4–6S multirotors. Hobbywing designs it for 650-class frames, and its current headroom suits heavy-lift hexacopters and octocopters. It is an OPTO unit with no BEC, so the flight controller and receiver need their own 5 V supply.

Key features

• 50 A continuous and 70 A peak current on 4–6S LiPo
• DEO (Driving Efficiency Optimisation) with active braking for faster motor deceleration and sharper throttle response
• Motor rotation and the built-in red/green navigation LEDs are set by DIP switch, so reversing a motor needs no rewiring
• Supports throttle range calibration; standard PWM input (OneShot is not supported)
• 14AWG wiring throughout, with 3.5 mm gold female bullets on the motor leads
