Hi Ross,

No harm done . Forums can be a bit impersonal. I have a Mechanical Engineering Degree so think I have something to offer people who are not sure, but they are only my views.

I'm new here, so am feeling my way around, and upon re-reading my initial post it came across as a bit critical, so apologies for that. Over the past couple of weeks I've been thinking alot about these forces and moments, and wondering what the ideal layout was. Psiron's post came at a time when I thought I was onto something and if anything every comes of it in the way of a useful spreadsheet, I'll post it up. Don't hold your breath though . . .

Anyway, time to hand this post back to Psiron . . . .
