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.

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.

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?

Mars Allan Sanidad / 26th May 2022

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?

James / 7th August 2017

Yes it would fit your Maverick and would be a good upgrade.
