## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-1049:1` (comma-separated SKU:qty pairs) and share the link. 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-1049:1.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)

## Description

This is a great general-purpose actuator for tiny mechanisms. The lead is terminated with a standard “JR”-style connector, which is Futaba-compatible. Mounting screws and an assortment of servo horns is included with this servo. The product picture shows an example of this included hardware (hardware might vary). You can find more information about this servo under the specifications tab and in its [datasheet](https://core-electronics.com.au/attachments/localcontent/HD-1800A_38136d35fde.pdf) (381k pdf).

Note that, as with most hobby servos, stalling or back-driving this servo can strip its gears.
