Vertical,
I have a similar setup on my D7. GTM full cockpit, done with GTM Lozenge fabric. I don't like to reinvent the wheel....I noticed that in one of your posts the your pilot was "removable". I was trying to do the same with mine. The cockpit is so fragile that I don't think I could attach the pilot to the seat. I was thinking of a platform that adjusts to grab the inside frame. How did you do yours?
