Reedy Sonic 540 M4 Brushless Motor 7.0t Modified

The Reedy Sonic 540-M4 is a purpose-built brushless motor engineered for competitive 1/12 scale pan car racing. Team Associated has refined this modified motor to deliver the linear powerband and responsive mid-range characteristics that serious racers demand. Whether you're competing in UK championships or practising at your local track, this RC brushless motor combines proven performance with measurable improvements over its predecessor.

Key refinements include a repositioned inner bearing now integrated into the can itself, which enhances rotor alignment within the magnetic field whilst reducing noise and vibration. The shortened motor body delivers superior weight distribution across your radio controlled car chassis, whilst the redesigned can shaves 5–10g from the overall weight. A balanced, high-strength rotor ensures fade-free performance even under sustained load, and precision stainless steel ball bearings handle high RPM demands reliably. With adjustable timing and full rebuildability, this RC car motor from Team Associated offers genuine competition-level versatility—fine-tune your setup with optional rotors to suit your specific track conditions and driving style.
