Product overview
The cysmodel CYS BLS5820 700 Helicopter Brushless Digital Swashplate Servo provides control actuation for 700 helicopters and fixed-wing aircraft, including jets. Its all-metal housing contains a brushless motor, titanium gears and dual bearings, with a 25T output spline for mechanical connection. The servo weighs 77±1g and has a 300mm lead. Its detailed dimensions are 40*20*39.35mm, while the description dimensions are 40*20*39mm. Electrical connections use brown/black for negative, red for positive and orange/white for signal.
The servo operates on 6.0-7.4V with PWM control, a 1500usec neutral position and a 1000usec ~ 2000 usec pulse range. Its reverse operating direction accompanies 90° total travel, with 45° to each side, and a 2usec deadband. At 6.0V, torque is 17kg.cm and no-load speed is 0.11sec/60°; at 7.4V, torque reaches 20kg.cm and no-load speed is 0.09sec/60°. Standby/no-load currents are 20mA/80mA and 20mA/100mA at those respective voltages. The temperature range is (-)10 to +50 °, and stall current is 3.0A/3.5A.
