Description

The Reedy 540-SL4 Sensorless Brushless Motor (AS907) is a 4-pole upgrade designed for powerful, efficient and reliable performance in a variety of RC applications. With a 3300kV rating, it delivers strong speed on 2S LiPo and very high top-end on 3S. A high-strength rotor provides excellent torque and improved heat resistance compared with many 2-pole designs. Flexible 12-gauge silicone leads and 3.5mm bullet connectors help minimise resistance and heat, while triple-insulated windings, a hardened steel shaft and oversized ball bearings enhance durability.

Features

  • Sensorless 4-pole design for efficient, reliable power delivery
  • 3300kV wind: quick on 2S LiPo, very fast on 3S
  • High-strength rotor for strong torque and improved thermal resilience
  • 12-gauge silicone wires with 3.5mm connectors to reduce resistance
  • Triple insulated windings, hardened steel shaft and oversized bearings for longevity

Specifications

REEDY 540-SL4 SENSORLESS BRUSHLESS MOTOR

Reedy's new 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.

Spec Check:

  • Cells: 2-3 LiPo, 4-9 NiMH
  • kV rating: 3300
  • Applications: 1:10 buggy, truck, touring car
  • Dimensions: 52mm x 36mm
  • Shaft Diameter: 3.17mm (1/8\")
  • Weight: 211g
  • Power Wires: 12-gauge silicone

Hi do you guys offer alternative motor and esc combos that will easily replace the stock mt 10. I broke the motor shaft so looking for something more durable but will easily fit
Matthew Gough / 23rd April 2023

Yes something like this HW38020345 and you would need a pinion gear with a 5mm shaft.

Steve @ Wheelspin Models
Is this motor compatible with my Arrma Senton 4x4 Mega?
Thomas Hardie / 15th February 2023

Yes that motor will fit and you will need a brushless esc too , we recommend this combo HW38010203

 

 

Steve @ Wheelspin Models
What are the heatsink with fan kit that fits this motor?

You can use  FAST36-1

Si @ Wheelspin Models
Will this work with a eTronix Photon 2.1FW Waterproof 60A ESC?
James / 7th August 2017

Ideally you'd want a higher power ESC. However, yes this would work at a basic level.

Ben @ Wheelspin Models
Will this fit in my maverick strada xb and provide plenty of power?
