## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-1191:1` (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-1191:1.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)

The Solarbotics SW wheel is compatible with standard Futaba servo hubs such as those on the [SpringRC SM-S4303R](https://core-electronics.com.au/springrc-sm-s4303r-continuous-rotation-servo.html) and [Power HD AR-3606HB](https://core-electronics.com.au/power-hd-continuous-rotation-servo-ar-3606hb.html) continuous rotation servos. The plastic wheel is molded from ABS and has a molded-on thermoplastic silicone tire with great traction and wear characteristics. There is a 64-strip encoder pattern on one side of the wheel compatible with the Wheel Watcher. The plastic wheels measure just under 2-5/8" (69 mm) across by 0.3" (7.62 mm) wide and are available in [blue](https://core-electronics.com.au/solarbotics-sw-lb-blue-servo-wheel-with-encoder-stripes-silicone-tire.html), [yellow](https://core-electronics.com.au/solarbotics-sw-y-yellow-servo-wheel-with-encoder-stripes-silicone-tire.html), [red](https://core-electronics.com.au/solarbotics-sw-r-red-servo-wheel-with-encoder-stripes-silicone-tire.html), and [black](https://core-electronics.com.au/solarbotics-sw-b-black-servo-wheel-with-encoder-stripes-silicone-tire.html).

**Note:** This Futaba servo wheel does not come with any mounting hardware. To mount the wheel, use the screw included with your servo.

#### Feature Summary

- Diameter: just under 2-5/8" (69 mm)
- Tire width: 0.3" (7.62 mm)
- Tire: molded-on thermoplastic silicone
- Encoder stripes: 64-strip pattern molded in on one side (compatible with the Wheel Watcher)
- Color options: [blue](https://core-electronics.com.au/solarbotics-sw-lb-blue-servo-wheel-with-encoder-stripes-silicone-tire.html), [yellow](https://core-electronics.com.au/solarbotics-sw-y-yellow-servo-wheel-with-encoder-stripes-silicone-tire.html), [red](https://core-electronics.com.au/solarbotics-sw-r-red-servo-wheel-with-encoder-stripes-silicone-tire.html), and [black](https://core-electronics.com.au/solarbotics-sw-b-black-servo-wheel-with-encoder-stripes-silicone-tire.html)

#### Installation

To install the wheel, remove the screw on your servo’s output shaft, push the wheel onto the shaft, and reinstall the screw. For some servos, such as the [SpringRC SM-S4303R](https://core-electronics.com.au/springrc-sm-s4303r-continuous-rotation-servo.html), the wheel might be a tight fit and not push onto the servo output shaft. In such cases, please try the method shown in this video:
