Feetech FS90 6V 1.5kg.cm 180° Analog Micro Servo

The Feetech FS90 is a 9 g analogue micro servo for light positional jobs: control surfaces on small foam planes, camera tilt on micro builds, light release latches, and robotics or classroom projects driven straight from a microcontroller.

Key features

• 1.5 kg.cm stall torque at 6V and 1.3 kg.cm at 4.8V
• 0.10 s/60° at 6V, 0.12 s/60° at 4.8V
• Runs from 4.8-6V, so a 5V BEC or receiver rail powers it directly
• About 120° of travel over 900-2100 µs pulses, up to 180° over 500-2500 µs
• POM plastic gears and a metal brush motor in an ABS case

Specifications

• Operating voltage: 4.8-6V
• Stall torque: 1.3 kg.cm at 4.8V, 1.5 kg.cm at 6V
• Rated torque: 0.5 kg.cm at 6V
• Speed: 0.12 s/60° at 4.8V, 0.10 s/60° at 6V
• Travel: 120° (900-2100 µs), 180° (500-2500 µs)
• Gears: POM plastic, no ball bearing
• Motor: metal brush
• Lead length: 250 mm
• Weight: 9 g
• Operating temperature: -15 to 70°C

Plastic gears can strip in a crash or under a stalled load; where that is a risk, the metal-gear FS90MG shares the same 22.5 x 12.1 mm footprint.
