It depends on what you mean by "ready"
The servos have been tested and work well in the plane.
The software for the AP will not be out until next month, so until then no non-beta customers are flying the AP.
Since the CT is an LSA (in the USA at least), you need to have factory authorization from them to install equipment in the plane, so it will be up to CT as to when they are willing to allow that. We are working with them, and they do already have servos and software for testing. You'll have to ask them what their plans are in this area.
We do not have immediate plans to offer a retrofit kit for the CTs ourselves. Flight Design will be your best resource for more information on retrofitability of CTs that are already in the field.
