Out Of Stock
Request Stock NotificationThe Reedy Sonic 540-SP5 13.5T Brushless Competition Motor (AS27481) delivers stock-class performance through a purpose-designed stator that maximises torque and power without sacrificing RPM. High-quality copper magnet wire, wound to the legal limit and treated with heat transfer epoxy, helps dissipate heat and reduce fade across a race. An oversized collector ring and thick, low-resistance solder tabs further minimise electrical losses while improving thermal management.
A balanced rotor with a high-strength magnet provides fade-free power and efficiency, supported by precision stainless steel ball bearings to handle high RPM loads. A high-quality sensor board ensures precise control. Externally, a lightweight two-piece CNC-machined aluminium housing with an aluminium end cap and adjustable timing allows fine-tuning for specific track conditions while contributing to improved handling and chassis setup flexibility.

REEDY SONIC 540-SP5 13.5T BRUSHLESS COMPETITION MOTOR
The incredible performance of the SP5 starts at the heart of the motor--the stator
Reedy's all-new Sonic SP5 stock motors feature an all-new and unique design, incorporating many features that will put it at the top of the pyramid when it comes to stock motor performance.
The incredible performance of the SP5 starts at the heart of the motor--the stator. Designed in-house, the stator's profile is intended to achieve maximum torque and power output without sacrificing RPM. High-quality copper magnet wire, sized to the maximum that the rules allow and wound with care to keep resistance near the legal minimum, is treated with heat transfer epoxy to dissipate heat and reduce internal temperatures resulting in less fade over the course of the race. An oversized collector ring not only dissipates heat, but in conjunction with thick solder tabs, reduces resistance and power loss.
A balanced rotor features a high-strength magnet that takes full advantage of dimensional rules to produce fade-free power with maximum effectiveness. The rotor is supported by precision stainless steel ball bearings to accommodate high RPM loads with exceptional efficiency and reliability. Like all Reedy Sonic motors, a high-quality sensor board rounds out the motor's interior.
Externally, the SP5 utilizes a lightweight two-piece CNC machined aluminum housing with an aluminum endcap and timing adjustability to accommodate fine-tuning for specific applications. This lightweight package is a welcome way to improve vehicle handling while improving chassis tuning flexibility.
