Thanks Trevor. I did see your edit but was tied up with work so couldn't react until now.
Incidentally the photo of the Kestrel was one I took at Bournemouth when it was visiting in 2007.
Here is the next challenge....this is how I used to draw aircraft when I was a kid - save for the fact I would put big engines on top of the tails! Nice to see one of the manufacturers take note
Needless to say, a project!
