FEETECH Ultra-High-Torque, High-Voltage Digital Giant Servo FT5335M - 3429

The FEETECH FT5335M servo is all about torque. This 1 4 scale digital servo can deliver an incredible 550 oz in of torque at 7.4 V or 480 oz in at 6 V thanks to its powerful motor and all metal gear train. The FT5335M 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. Key specs at 7.4 V 0.18 sec 60 , 550 oz in (40 kg cm), 180 g. Compare all products in RC Servos or FEETECH Servos. May 2023 update Feetech has changed the case color of these from red to silver. The dimensions and functionality remain the same. The FT5335M is a giant scale (also called 1 4 scale or mega scale) digital servo from FEETECH that can deliver more than twice the torque of our strongest standard size servo , offering up to 550 oz in at 7.4V or 480 oz in at 6 V (if you need even more torque than this, check out the much larger Torxis monster servos , and if you need a lot of torque in a smaller size or with more speed, consider the FT5121M and FT5313M high torque digital servos ). The picture on the right shows how the giant size FT5335M compares to a standard size servo. The FT5335M works with standard RC servo pulses, providing a running angle of approximately 120 over a servo pulse range of 900 s to 2100 s. 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 FT5335M significantly beyond 120 (the servo did not respond to pulses below around 900 s or above around 2100 s). This servo has a 12 (30 cm) cable that is terminated with a standard Futaba J connector. Unlike typical hobby servos, the FT5335M has an operating voltage range of 6 V to 7.4 V. Note This servo can draw bursts of current in excess of 9 A at 7.4 V, so please make sure you have an appropriate power supply. For comparison, a typical standard size servo might draw around an amp when straining. For more advanced robotics applications, please note that we also carry a version of this servo that is specially modified to provide access to the feedback potentiometer through a fourth (green) wire, which lets you monitor the actual position of the servo from your controller The included servo horns are plastic, but we also carry a compatible metal horn (sold separately) that can be used as a more robust lever arm in ultra high torque applications The picture below shows the all metal gear train that helps the servo deliver such high torque You can find more information about this servo in its datasheet (111k pdf). Note that, as with most hobby servos, stalling or back driving this servo can damage it. Comparison to the Power HD 1235MG giant servo This servo is a lower cost alternative to the very similar 1235MG from Power HD. The two servos are approximately the same size, though the mounting hole spacing differs between the two, and they have almost identical performance specifications. The output shaft of the 1235MG is supported by two ball bearings for reduced friction while the output shaft of the FT5335M is supported by bushings. The picture below shows both the FT5335M and the 1235MG side by side The servo output splines have the same number of teeth, but the diameter of the one on the FT5335M is approximately 0.2 mm bigger. This means that the servo horns included with the FT5335M can be used with the 1235MG, but not the other way around.
