The FT5313M is a standard-size digital servo from FEETECH that is capable of delivering extra-high torque normally associated with more expensive or larger servos thanks to its powerful coreless motor and an all-metal gear train. The output shaft is supported by two ball bearings for reduced friction. Servo horns and associated hardware are included. This servo can work with both 5 V and 3.3 V servo signals.Key specs at 6 V: 0.10 sec/60°, 190 oz-in (13.8 kg-cm), 60 g.
