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.

Key specs at 7.4 V: 0.18 sec/60°, 550 oz-in (40 kg-cm), 180 g.

Overview

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). The picture on the right shows how the giant-size FT5335M compares to a standard-size servo.

This servo works with standard RC servo pulses and 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.

The picture below shows the all-metal gear train that helps the servo deliver such high torque:

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.
