Product overview
The cysmodel CYS-S2109 9Kg Titanium-Gear Coreless Helicopter Servo is a digital actuator for 600-700 helicopter swashplate and fixed-wing applications. Its configuration combines a coreless motor, dual bearings, metal gears and a 25T output spline. The body measures 40*20*39mm and weighs 54±1g, establishing the space and mass needed for installation. A 300mm lead provides the electrical connection, with brown/black identifying negative, red positive and orange/white the signal conductor. The product is a servo component rather than a flight platform or airframe kit.
Integration requires a 6.0-7.4V supply and PWM control with a 1500usec neutral position. Reverse operation is specified across 1000usec ~ 2000 usec, with 90° total travel and 45° to either side. Voltage-specific ratings give 10kg.cm and 0.09sec/60° at 6.0V, increasing to 11kg.cm and 0.08sec/60° at 7.4V; speed figures are no-load values. Separate descriptive ratings list 8.0Kg.cm ~ 9.0Kg.cm and 0.11sec ~ 0.09sec/60°. Electrical planning must also accommodate the specified 2.5A/2.8A stall current. The temperature range is (-)10 to +50 °.
