DYS GoTeck GS-D9257MG 6kg Digital Servo, Full Metal Gear

The GoTeck GS-D9257MG from DYS is a fast mini-size digital servo with a coreless motor and full metal gears, delivering 6 kg-cm at 6V with a 0.06 s/60° transit. That combination of pace and torque suits helicopter swashplates, control surfaces on mid-size planes and gliders, camera gimbals, RC car steering and robotic joints.

Key features

• Coreless motor: 0.07 s/60° at 4.8V, 0.06 s/60° at 6V
• 5.0 kg-cm at 4.8V, 6.0 kg-cm at 6V
• Full metal gear train running on two ball bearings
• FET drive with a 2 µs dead band and 333Hz support for precise holding
• 180° travel, with overload protection that cuts current when the output is stalled

• Lead: 250mm, 26AWG (brown -, red +, orange signal)

It is not a high-voltage servo: keep the supply at 4.8-6V from a BEC sized for all the servos on the model, and never run it straight from a 2S pack.
