HobbyStar 4585 4-Pole Brushless Sensorless Motor, 1/7 Scale – 1580KV


Available on backorder

SKU: 4858 Category:


The HobbyStar 4585 motor is a behemoth powerplant for larger-scale applications such as the Traxxas Xmaxx/XO1 and any other application where an 1/8-sized motor is not enough and a 1/5 can is too large. 4-pole design and a 12-slot stator provide unbelievable torque. High-quality features like a beautifully machined 6061 T6 billet-aluminum can, buttery-smooth ABEC5 bearings and a 85mm length make this the ultimate motor for your large-scale rig.

NOTE: Aftermarket mount is required for use in the Xmaxx as the stock motor uses a unique “pin” mounting system.
