Request Stock NotificationThe Reedy Sonic 540-SP5 17.5T Brushless Competition Motor (AS27480) is engineered for stock-class performance, delivering maximum torque and power without sacrificing RPM. Built to ROAR specifications, this latest SP5 design focuses on efficient heat dissipation and ultra-low resistance to provide consistent, fade-free power throughout a race.
Performance Overview
At the heart of the SP5 is an in-house designed stator profile optimised for torque, power and RPM balance. High-quality copper magnet wire is sized to the legal maximum and wound to keep resistance near the minimum, then treated with heat transfer epoxy to move heat away from the windings. An oversized collector ring, paired with thick solder tabs, further reduces resistance and helps shed heat.
A balanced rotor uses a high-strength magnet designed within dimensional rules for efficiency and stability at high RPM. Precision stainless steel ball bearings support the rotor for smooth, reliable operation, while a high-quality sensor board ensures accurate, linear throttle response. Externally, a lightweight two-piece CNC-machined aluminium can and aluminium end cap with adjustable timing offer fine-tuning and improved chassis balance.

REEDY SONIC 540-SP5 17.5T 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.
