Product overview
The cysmodel CYS-S2909 600 Helicopter All-Metal Coreless Digital Servo is a control actuator intended for 700 helicopter tail-rudder and fixed-wing applications. Its physical assembly combines an all-metal aluminum housing, a coreless motor, titanium gears and dual bearings, with a 25T output spline. The servo measures 40*20*39.35mm and weighs 68±1g. Its 300mm lead uses brown/black for negative, red for positive and orange/white for signal, defining the electrical connections alongside the mechanical integration dimensions.
The servo operates at 6.0-7.4V using PWM control, with a 1500usec neutral position and a 1000usec ~ 2000 usec pulse range. Operation is reverse, with travel of 90° total and 45° each side, and a 2usec deadband. At 6.0V, no-load speed is 0.11sec/60° and torque is 8kg.cm; at 7.4V, these values are 0.09sec/60° and 11.2kg.cm. Standby/no-load current is 20mA/80mA at 6.0V and 20mA/100mA at 7.4V. Stall current is 2.5A/3.0A, and the temperature range is (-)10 to +50 °.
