Reedy Sonic 540 M4 Brushless Motor 6.0T Modified de Version

The Reedy Sonic 540 M4 Brushless Motor 6.0T Modified Driver Edition (AS27493) was developed with input from the international Reedy racing team. Technically identical to the standard 540-M4, this Driver Edition is factory-fitted with the AS27447 rotor. This lowest-strength rotor option is reported to deliver a smoother, more consistent throttle feel that can translate into improved lap times on the track.

Engineered for elite racing, the Sonic 540-M4 DE combines a CNC-machined lightweight can with precision internals and fully adjustable timing. It is completely rebuildable for long-term serviceability and fine-tuning. All Sonic 540-M4 variants, including this 6.0T, are approved by ROAR, EFRA, BRCA and IFMAR, making it a strong choice for sanctioned competition using 1–2S LiPo power.
