Reedy Sonic 540 M4 Brushless Motor 6.0t Modified

The Reedy Sonic 540-M4 is a competition-proven brushless motor engineered for 1/12 scale pan car racing. As part of Team Associated’s renowned Reedy motor range, this 6.0t modified motor delivers the linear powerband and responsive mid-range characteristics that have made Associated Electrics a favourite among serious racers. Designed specifically for radio controlled car enthusiasts, it combines precision engineering with proven race-winning performance.

Key refinements over its predecessor include a relocated inner bearing integrated into the can for superior rotor alignment, reduced noise and vibration. The shortened motor body improves weight distribution and saves 5–10g, critical for competitive advantage. Built with a balanced, high-strength rotor, dual precision stainless steel ball bearings, and a high-strength magnet, this RC brushless motor delivers fade-free performance even under demanding conditions. The CNC-machined lightweight can and low-resistance silver-plated solder tabs ensure efficiency and reliability. ROAR, EFRA, and IFMAR approved, it’s ideal for those seeking top-tier RC car parts UK racers trust.
