Product overview
The cysmodel CYS-S0403 is a miniature analog servo for miniature fixed-wing aircraft and foam aircraft. Its physical configuration combines plastic gears, a coreless motor, no bearings and a 24T output spline. Measuring 19.8 × 8.4 × 23.3mm, it occupies a small installation envelope and has a 150mm lead for electrical connection. Weight is specified as 4.3g, with a separate weight specification of 4.3±0.1g. This is an aircraft actuation component, rather than a complete flight platform or airframe kit.
Integration uses PWM control with a 1500usec neutral position, reverse operation and a 1000usec ~ 2000 usec pulse range. Travel totals 90°, or 45° to either side, with a 4usec deadband. The detailed operating range is 4.2~4.8V, giving 0.6kg.cm at 4.2V and 0.8kg.cm at 4.8V. The overview voltage and speed figures differ from the detailed ratings; both sets are retained below. The temperature range is (-)10 to +50 °, without an identified temperature scale.
