The Power HD 1235MG servo is all about torque. This 1/4-scale servo can deliver an incredible 560 oz-in of torque at 7.4 V or 490 oz-in at 6 V, and it features an all-metal gear train, digital control electronics, and two ball bearings on the output shaft. Unlike typical hobby servos, the 1235MG has 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°, 560 oz-in (40 kg-cm), 170 g.
The HD-1235MG is a giant-scale (also called 1/4-scale or mega-scale) digital servo from Power HD can deliver nearly twice the torque of our strongest standard-size servo, offering up to 560 oz-in at 7.4V or 490 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 1235MG compares to our popular 1501MG standard-size servo.
The entire gear train is metal, and the output shaft is supported by two ball bearings for improved performance. Unlike typical hobby servos, the 1235MG has an operating voltage range of 6 V to 7.4 V. This servo works with standard RC servo pulses at frequencies up to 333 Hz. The 12″ (300 mm) lead is terminated with a standard “JR”-style connector, which is Futaba-compatible.
The picture below shows an example of the hardware that might be included with this servo (hardware might vary):

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:

You can find more information about this servo under the specifications tab and in its datasheet (382k pdf).
Note that, as with most hobby servos, stalling or back-driving this servo can strip its gears.
