Hobbywing XRotor X13 18S 45KV Power System

Hobbywing's XRotor X13 is an 18S propulsion unit for agricultural spray, cargo and heavy-lift multirotors, pairing a 45KV motor with an integrated ESC. It is available with the matching MFP 56x20 propeller in CW or CCW rotation, or as a CCW motor-and-ESC unit without a propeller for replacing a damaged motor while keeping your existing prop.

Key features

• 57 kg maximum thrust per axis at sea level, with a recommended take-off weight of 25–27 kg per axis at 8.2–8.6 g/W

• Φ138 × 25 mm stator in a 36N42P layout, built for 18S LiPo (70 V rated, 24–81 V input)

• Integrated ESC: 80 A continuous, 200 A peak (3 s), UAVCAN communication, PWM + CAN throttle and fault storage

• IPX6 protection and a 50 mm arm-tube mount for wet spraying work

• Propeller versions ship with the MFP 56x20 propeller in carbon-fibre-reinforced nylon composite

Run it on 18S LiPo (66.6 V nominal) and set the flight controller's motor outputs to 1050–1950 µs, since the ESC's throttle range cannot be calibrated.
