Sign in to order →Provide your model with powerful and precise control. This servo is designed for serious applications. It combines high performance and reliability. Your drone or model will work flawlessly. It's a smart choice for demanding pilots.
High torque of 20 kg/cm for heavy loads.
Durable gearbox made of metal gears.
Waterproof and dustproof housing.
Digital control for precise positioning.
Wide operating voltage range 4.8V – 7.4V.
These advantages ensure stable operation in any conditions. A power of 20 kg/cm is sufficient for most tasks. Metal gears guarantee long service life. The protected body allows you to fly in difficult weather. Digital control gives maximum precision.
The device receives a signal from a receiver or controller. Built-in electronics analyze the received data. A powerful motor begins to rotate at a given speed. Through the gearbox, the movement is transmitted to the output shaft. The shaft rotates at a given angle with great force.
The operating principle is based on digital signal processing. The microprocessor accurately tracks the position of the output shaft. The system automatically adjusts the engine power. This ensures the highest positioning accuracy. You get smooth and predictable behavior of the model.
DSSERVO RDS3218 has excellent parameters. The operating voltage is 4.8V – 7.4V. Torque reaches 20 kg/cm at 6.8V. Rotation speed – 0.18s/60° at 6.8V. Control type – digital signal 1520μs. Device dimensions – 55.0×20.0×40.0 mm.
The servo weighs 65 grams. This is a good indicator for such power. The durable case protects the mechanism from moisture and dust. Metal gears can withstand high loads. The shaft on the bearing minimizes play and vibration.
The servo drive is ideal for large quadcopters. It is great for airplanes and helicopters. Also for automotive models and robotics. He will handle the chassis and camera controls. You will be able to create reliable mechanical systems.
Installation is carried out with standard screws. The wire is long enough for easy connection. Compatible with most receivers and controllers. This allows for easy integration into your model.
