Key Features

  • Powerful 4-pole sensorless design
  • Oversized precision ball bearings
  • High-strength rotor
  • Hardened steel shaft
  • Triple insulated windings
  • Flexible silicone wires
  • Low-resistance connectors

Overview

Reedy's 540-SL4 is the perfect upgrade for your RTR! Due to its sensorless 4-pole configuration, the 540-SL4 operates powerfully, efficiently, and reliably in a variety of vehicles and applications.

The 3300kV rating provides plenty of speed with 2S LiPo batteries. But install a 3S LiPo battery for insane speeds that are barely controllable! A high-strength rotor provides plenty of torque and resists overheating better than 2-pole alternatives.

Flexible silicone wires ease wire routing in tight spaces and work in conjunction with 3.5mm bullet connectors to reduce power-robbing resistance and heat. Triple insulated windings, a hardened steel shaft, and oversized ball bearings enhance reliability to keep you out of the pits and on the track.
