Thanks to every one you have no idea how your help has uplifted me. Getting this RASA to work has it's ups and downs and just when I thought I was ahead as I found that I wasn't.
I post a link to a video here that although somewhat tedious may be interesting to folk who have a RASA.
He refers to a guy who helped him so I have se t him an email to see if I can get my hands of a solution to the issues of fitting a camera etc
