That seat looks great, Patrick. Your cockpit assembly is excellent and you seem to have avoided the problems I did (such as pulling the rigging too tight and warping the frames).
Are you going to glue the fuselage together and slide the cockpit in from the front, or fit the cockpit and then glue the fuselage together? For my build I glued the fuselage first, so I could fit the lower wing, fix the seams and paint them. I then attempted to slide in the cockpit assembly and found I had to sand the rear rear cockpit frame and the inside of the fuselage, so the cockpit would easily fit into the fuselage.
If I was to build another of these I'd fit the cockpit to the fuselage before gluing it together, ensuring that the firewall (part 7B) fitted properly (if the cockpit is sitting too far forward it makes it difficult to fit the firewall). Then I'd fit the lower wing and paint it and the fuselage together, so I could avoid doing the touch up painting I had to do.
Cheers.
