Product overview
The cysmodel CYS-S3215 8Kg High-Performance Digital Servo serves model control applications, including 500-550 direct swashplate mechanisms, 1/12 racing model cars and fixed-wing Jet/CAP models. Its all-metal construction incorporates a coreless motor, metal gears and dual bearings, with a 25T output and a 300mm lead. Dimensional specifications differ between 35*15*29.5mm and 35*15*32.8mm, while weight specifications differ between 43g±1g and 45g. These differing dimensions and weights leave the physical specification unresolved for installation planning.
The servo operates at 6.0-7.4V with PWM control, a 1500usec neutral position and a 2usec deadband. Reverse operation covers a 1000usec ~ 2000 usec pulse range, with 90° total travel and 45° each side. Voltage-specific torque figures are 9kg.cm at 6.0V and 10kg.cm at 7.4V; corresponding no-load speeds are 0.067sec/60° and 0.055sec/60°. Separate specifications give 7.0Kg.cm ~ 8.0Kg.cm and 0.07sec ~ 0.06sec/60 °, leaving differing performance figures. The temperature range is (-)10 to +50 °, and stall current is 2.6A/3.2A.
