The Turnigy TrackStar stock specification 540 brushless motors offer outstanding performance at an incredible price! The unique stator design provides strong torque and a high RPM. Their CNC-machined 7075 aluminum case and titanium-magnesium alloy heat sink dissipate heat extremely well, allowing them to run at very low temperatures.

The stator is electro-plated to prevent tarnishing and rusting, and the American standard high-purity copper windings provide maximum conductivity.
They also feature adjustable timing, which can be adjusted in both directions for CW and CCW rotation. This allows for fine-tuning the performance of your vehicle while the dual sensor ensures smooth start-ups and acceleration. They are also fitted with original NSK R2ZZ Japanese bearings which ensure very smooth and vibration-free running at speeds up to 80,000rpm.

The TrackStar stock 540 1/10th brushless motors are suitable for 1/10th scale on-road, and off-road cars, trucks, and buggies. These motors also comply with ROAR, IFMAR, BRCA, and EFRA specifications.
