## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GB-33788:1` (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/GB-33788:1.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

The Hitec HS-788HB servo is based around the long-time favorite, the HS-785HB. This new model was created with a 25 tooth output spline in order to conform with the majority of the hobby servo market. Similar to its 24 tooth cousin, this model is able to rotate multiple turns while retaining positioning feedback. Conventional servos are typically limited to a maximum of 180 degrees, which, in the steering mechanism of a remote controlled car, is plenty. Many other applications demand more than conventional servos can provide. The HS-788HB has an underdriven potentiometer so the distance it moves in relation to the output shaft is less. This allows the output shaft of the servo to turn nearly eight full rotations before the outer limits of the potentiometer are met. The final output shaft of the servo is supported by a pair of ball bearings and the gears are constructed of Karbonite plastic to provide excellent wear resistance.

The HS-788HB servo comes with a dual spool style winch pulley for those who wish to install in a pull-pull setup. The included servo horn screw has aggressive threads and a 2.5mm socket head drive so that you can tighten the horn onto the servo without concern of rounding out the head. The included servo mounting hardware (grommets, eyelets and screws) can be discarded when mounting in a goBILDA servo mount but can be used when mounting to wood or plastic structures, where vibration dampening is needed.
