Product overview
The cysmodel CYS-BLS3310 is a digital servo for control actuation in 500-550 helicopters, fixed-wing aircraft and model cars. Its all-metal construction combines a brushless motor, dual bearings and titanium-plated aluminum gears, with a 25T output spline for mechanical integration. The specification dimensions are 35*15*32.8mm and weight is 45±1g. A 300mm cable, measured without the plug, provides the electrical connection. Wire identification assigns brown/black to negative, red to positive and orange/white to the signal connection.
Control uses PWM with a 1500usec neutral position, reverse operation and a 1000usec ~ 2000 usec pulse range. Travel totals 90°, or 45° per side, with a 2usec deadband. At 6.0V, torque is 4kg.cm and no-load speed is 0.05sec/60°; at 7.4V, these become 5kg.cm and 0.04sec/60°. Operating voltage spans 6.0-7.4V. Dimensional and mass figures are inconsistent: descriptive figures also give 35*15*29.5mm and 43g±1g, alongside a separate speed range of 0.04sec ~ 0.03 sec/60 °.
