Reedy Sonic 540-M4 Modified Brushless Motor 7.0 DE (ASC27491)

The Reedy Sonic 540-M4 Driver Edition Modified Brushless Motor, 7.0-turn, is a high-performance 540-class powerplant built for competitive RC racing. While essentially the same as the standard 540-M4, this Driver Edition uses a low-strength rotor to sharpen throttle response and deliver more consistent power, helping you post faster, more reliable lap times.

All Sonic 540-M4 versions are approved by ROAR, EFRA, BRCA, and IFMAR, and the Driver Edition is offered in multiple wind configurations to suit different track conditions and driving styles. This makes it a versatile choice for 1/10-scale electric vehicles seeking predictable power and smooth throttle during race days.
