DYS GoTeck GS-D9025MG 9g-Class Digital Micro Servo, Full Metal Gear

The GoTeck GS-D9025MG from DYS is a digital micro servo in the familiar 9g-class case, fitted with a full metal gear train and a ball bearing for linkages that see real loads. It weighs 14g, a few grams more than a plastic-gear 9g servo, in exchange for gears that resist stripping when a surface takes a knock. It suits ailerons, elevators and rudders on park flyers and small gliders, small helicopters, RC car steering and light robotics.

Key features

• Hard-anodised full metal gear train for wear resistance
• 2.8 kg-cm at 6V with a 0.10 s/60° transit
• Digital amplifier with a 4 µs dead band and 333Hz support for tight centring
• 180° travel, with overload protection that cuts current when the output is stalled
• Single ball bearing on the output and a POM case

Specifications

• Operating voltage: 4.8-6V
• Torque: 2.2 kg-cm at 4.8V, 2.8 kg-cm at 6V
• Speed: 0.12 s/60° at 4.8V, 0.10 s/60° at 6V
• Rotation: 180°
• Weight: 14g
• Dimensions: 23 x 12.1 x 28.8 mm
• Neutral / frame rate: 1520 µs / 333Hz
