Feetech FS5103B 6V 3.2kg.cm 180° Analog Servo

The Feetech FS5103B is a standard-size analogue servo with 180° of positional travel and 3.2 kg.cm of stall torque at 6V. It fits standard 40 x 20 mm servo mounts and suits control surfaces on trainer and sport planes, pan-tilt heads, robot arms and payload release latches on larger drones.

Key features

• Wide 4-8.4V supply range covers 5-6V BECs and 2S LiPo receiver packs
• Ball-bearing output shaft with a POM plastic gear train
• 25T (5.9 mm) output spline takes standard-size servo horns
• 180° ±5° travel over 600-2400 µs pulses; about 120° over the common 900-2100 µs RC range
• 0.125 s/60° no-load speed at 6V
