MG90S Metal Gear Micro Servo

The MG90S is a 13 g micro servo with a metal gear train for small RC plane control surfaces, camera-tilt and payload-release mechanisms on drones, and small robots. Choose the standard 180° version for position control or the 360° continuous-rotation version for drives.

Key features

• Metal gears stand up to knocks and stalls better than plastic-gear 9 g micro servos
• 1.8 kg·cm stall torque at 4.8 V, rising to 2.2 kg·cm at 6.6 V
• Runs on 4.8–6.6 V, straight from a receiver or a 5–6 V BEC
• JR-type 3-pin plug fits standard receivers and flight controller servo outputs
• Supplied with one-, two- and four-point horns and screws

Specifications

• Weight: 13 g
• Operating voltage: 4.8–6.6 V
• Stall torque: 1.8 kg·cm (4.8 V), 2.2 kg·cm (6.6 V)
• Speed: 0.10 s/60° (4.8 V), 0.08 s/60° (6.6 V)
• Gears: metal
• Plug: JR, about 25 cm lead

The 360° version has no position control: the PWM signal sets speed and direction rather than angle, so pick the 180° version for control surfaces and release mechanisms.
