The output shaft is supported by two ball bearings for reduced friction. The FT5121M is a high-voltage servo, offering an operating voltage range of 6 V to 7.4 V. Servo horns and associated hardware are included. This servo can work with both 5 V and 3.3 V servo signals.\u003cbr\u003e\u003cbr\u003e Key specs at 7.4 V: 0.12 sec\/60°, 285 oz-in (20.5 kg-cm), 60 g.\u003c\/p\u003e\n\n\u003cbr\u003e\u003ch2\u003e Overview\u003c\/h2\u003e\n\n \u003cp\u003eThe FT5121M is a standard-size digital servo from FEETECH that can deliver over three times the torque of our standard-size servos with plastic gears thanks to its powerful coreless motor and all-metal gear train (if you need even more torque than this, check out the larger \u003ca href=\"https:\/\/www.pololu.com\/product\/3429\"\u003eFT5335M giant servo\u003c\/a\u003e , which can deliver 550 oz-in at 7.4 V, and if you need more speed in a servo with the same dimensions as the FT5121M, consider the \u003ca href=\"https:\/\/www.pololu.com\/product\/3428\"\u003eFT5313M\u003c\/a\u003e ).

Many hobby servos can be operated beyond their standard ranges by using a wider pulse range, but please note that in our tests, we were not able to expand the range of the FT5121M significantly beyond 120° (the servo did not respond to pulses below 800 µs or above around 2100 µs, providing an approximate expanded range of 135°).\u003c\/p\u003e\n\n\u003cp\u003e This servo has a 10″ (25 cm) cable that is terminated with a standard \u003ca href=\"https:\/\/www.pololu.com\/product\/1924\"\u003eJR-style connector\u003c\/a\u003e , which is Futaba-compatible. typical hobby servos, the FT5121M has an operating voltage of 6 V to 7.4 V.
