Product overview
The Cysmodel CYS-S3019 digital plastic-gear servo is designed for fixed-wing aircraft. Its construction combines an iron-core motor, plastic gears and a 25T output spline, with metal gears also available as an option. The servo has a 180mm lead, with brown/black negative wiring, red positive wiring and orange/white signal wiring. It operates at 4.8-6.0V, and a modified high-voltage version supports 7.4V operation.
PWM control uses a 1500usec neutral position and a 3usec deadband. Travel is 90° in total, with 45° on each side, and operation is reverse over a 1000usec ~ 2000 usec pulse range. At 4.8V, no-load speed is 0.13sec/60° and torque is 2.5kg.cm; at 6.0V, these values are 0.09sec/60° and 3.0kg.cm. Standby and no-load current are 20mA and 80mA respectively at either voltage.
