Product overview
The cysmodel CYS-S2912 600 Helicopter All-Metal Coreless Digital Servo is a rotary actuator with an aluminum housing, coreless motor, titanium gears and dual bearings. Its application includes swashplate actuation on 700 helicopters. The servo measures 40*20*39.35mm and weighs 68±1g, defining the component envelope and mass for installation. A 25T output spline provides the mechanical connection, while a 300mm lead provides the electrical connection. Control uses PWM with a 1500usec neutral position, reverse operation and a pulse range of 1000usec ~ 2000 usec.
Operation requires 6.0-7.4V, with total angular travel of 90°, or 45° each side, and a 2usec deadband. At 6.0V, torque is 14.3kg.cm and no-load speed is 0.12sec/60°; at 7.4V, these become 15.6kg.cm and 0.10sec/60°. Standby/no-load current is 20mA/80mA at 6.0V and 20mA/100mA at 7.4V. Stall current is 2.3A/3.1A. The descriptive dimensions of 40*20*39mm and torque range of 11Kg.cm ~ 12Kg.cm differ from the detailed specifications. The temperature range is (-)10 to +50 °.
