BLS159 Low Profile Brushless HV Digital Servo 15Kgf.cm 0.11sec/60degree for RC Car Buggy
KST BLS159 Low Profile HV Brushless Servo
The KST BLS159 is a low-profile HV brushless digital servo designed for RC cars where installation space is limited but strong and precise steering performance is required. Its CNC-machined aluminum housing and durable metal geartrain provide a rigid and reliable structure for demanding driving conditions.
Supporting a wide 6.0–8.4V input voltage range, the BLS159 offers flexible compatibility with a variety of RC power systems while maintaining consistent servo performance.
Its low-profile design makes it an excellent choice for 1/10 2WD and 4WD buggies, 1/10 drift cars, and other RC vehicles where a compact servo is required.
Combining brushless performance, metal gearing, CNC aluminum construction, and a space-saving low-profile design, the BLS159 is built for precise and reliable steering control.
