Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/POLOLU-3426:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description The FS5115M is a standard-size analog servo from FEETECH that can deliver more than twice the torque of Pololu's standard-size servos with plastic gears thanks to its powerful motor and all-metal gear train (if you need even more torque than this, check out the larger [FT5335M giant servo](https://core-electronics.com.au/feetech-ultra-high-torque-high-voltage-digital-giant-servo-ft5335m.html)). The output shaft is supported by two ball bearings for reduced friction. The FS5115M works with standard RC servo pulses, providing a running angle of approximately 180° over a servo pulse range of 500 µs to 2500 µs, and it has a 12" (30 cm) cable that is terminated with a standard [JR-style connector](https://core-electronics.com.au/jr-connector-pack-female.html), which is Futaba-compatible. You can find more information about this servo in its datasheet (133k pdf). | \| [![](https://core-electronics.com.au/attachments/localcontent/0J7699_1400727d771.jpg)](https://core-electronics.com.au/attachments/localcontent/0J7699_12106677ddb.jpg) \| \|---\| \| The servo cable is terminated with a Futaba-compatible JR-style connector. \| | \| [![](https://core-electronics.com.au/attachments/localcontent/0J7697_2310661d1a8.jpg)](https://core-electronics.com.au/attachments/localcontent/0J7697_103338d72e3.jpg) \| \|---\|---\| \| FEETECH High-Torque Servo FS5115M with included hardware (actual hardware might vary). \| | |---| For more advanced robotics applications, please note that Pololu also carry a [**version of this servo that is specially modified**](https://core-electronics.com.au/feetech-high-torque-servo-fs5115m-fb-with-position-feedback.html) 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: | [![](https://core-electronics.com.au/attachments/localcontent/0J9685_28473043e2d.jpg)](https://core-electronics.com.au/attachments/localcontent/0J9685_295325c80ed.jpg) | |---| | FEETECH High-Torque Servo FS5115M-FB with Position Feedback. | This servo is also compatible with Pololu's [Mounting Bracket for Standard-Size Servos](https://core-electronics.com.au/mounting-bracket-for-standard-size-servos.html): | [![](https://core-electronics.com.au/attachments/localcontent/0J9430_199093972af.jpg)](https://core-electronics.com.au/attachments/localcontent/0J9430_5358682e364.jpg) | |---| The picture below shows the all-metal gear train that helps the servo deliver such high torque: | [![](https://core-electronics.com.au/attachments/localcontent/0J7698_4248708e761.jpg)](https://core-electronics.com.au/attachments/localcontent/0J7698_19033bc9cde.jpg) | |---| 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 Power HD 1501MG high-torque servo** This servo is a lower-cost alternative to the [1501MG](https://core-electronics.com.au/power-hd-high-torque-servo-1501mg.html) from Power HD, which has nearly identical dimensions and similar performance. The two servos should be generally interchangeable for most applications.
