I put together a site making workshop/parts manuals on CD available. There's one for the Clouds that would answer those questions, plus ones you'll come up with in the future.

You can click on the Rolls Royce section on the left, and scroll down to the Cloud manual
More specifically, the Cloud CD is directly here:
