About this product
The Reedy Sonic 540-M4 is a precision-engineered brushless motor that delivers consistent performance across the entire power band. Team Associated has refined this modified RC motor to offer exceptional mid-range feel and linear throttle response that competitive racers demand. The relocated inner bearing is now integrated into the can itself, ensuring perfect rotor alignment within the magnetic field whilst significantly reducing noise and vibration for a smoother driving experience.
This radio controlled car motor benefits from a shortened profile that optimises weight distribution within your chassis, whilst the improved can design shaves 5-10g from the overall weight. The balanced, high-strength rotor provides fade-free performance even under demanding conditions. Available in multiple turn options including this 9.5T variant, the Sonic 540-M4 allows you to fine-tune your RC car parts setup for your specific track. Built to ROAR/EFRA/IFMAR specifications and competition-proven, this motor is fully rebuildable and compatible with 1-2S LiPo batteries.
