Power HD High-Torque Servo 1501MG
The HD-1501MG is a powerful standard-size servo that features metal gears and two ball bearings and can deliver a tremendous amount of torque for a servo this fast (if you need even more torque than this, check out the larger 1235MG giant servo). The 1501MG works with standard RC servo pulses, providing a running angle of approximately 165° over a servo pulse range of 800 µs to 2200 µs, and it has a 10″ (25 cm) cable that is terminated with a standard JR-style connector, which is Futaba-compatible.
The pictures below show the metal gear train and ball bearings that help the servo deliver such high torque.
You can find more information about this servo under the specifications tab and in its datasheet (380k pdf).
Note that, as with most hobby servos, stalling or back-driving this servo can damage it. This servo can draw bursts of current in excess of 3 A at 6 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.
Comparison to the FEETECH FS5115M high-torque servo
The FS5115M high-torque servo from FEETECH is a lower-cost alternative to the 1501MG with nearly identical dimensions and similar performance. The two servos should be generally interchangeable for most applications. The picture below shows both the FS5115M and the 1501MG side by side:
|Size:||40.7 x 20.5 x 39.5 mm|
|Speed @ 6V:||0.14 sec/60°|
|Stall torque @ 6V:||17 kg·cm|
|Speed @ 4.8V:||0.16 sec/60°|
|Stall torque @ 4.8V:||15.5 kg·cm|
|Lead length:||10 in|
