Features:

• 25A sensorless ESC built for brushless systems，40% more efficient than stock brushed ESC.
• High speed (1:24.75)：Sparse ratio for flat-out runs – 35% faster top speed (22km/h), 0.8s quicker 0-15km/h acceleration vs stock;
• Low speed (1:99)：Dense ratio for 4x more torque – 92% success on 45° slopes (55% stock), better power distribution during single-wheel lifts.
• Neodymium magnets and pure copper windings deliver 70% higher RPM (21,000 at 7.4V) than stock brushed. Brushless design lasts 5x longer, no carbon brush replacements needed.
• The power is 100% higher than the original.
• CNC machining process utilized, ensuring enhanced product precision, eradicating roughness, attaining seamless fitting, and streamlining installation.
• Plug-and-Play Upgrade,Factory mounting holes ensure zero-error installation,5 minute install, no mods needed.
• There are plenty of accessories, which can meet the needs of upgrading many small parts.
• note:Stock brushed ESC lacks brushless motor protocols – forced connection causes jamming or burnout. Stock remote has no 3rd channel for 2-speed shifting. Requires 3rd-channel remote (e.g., Flysky NB4) + brushless ESC for gear changes.
