The seat bottom and back have been mocked up with plywood and butt-tested by many BCAC members. The angles and dimensions used are very close to those on Terry's RV-9 and corresponded with "best-practices" from leading textbooks on aircraft design. Next comes fabrication of the seat bottom and back as well as the seat cushions.
Terry adds a small reinforcement tape to the horizontal stabilizer.
Seat bottom and seat back mocked up and in place. We gained two additional inches of headroom by dropping the base of the seat back into the original curved seat pan. Visibility out the front remains good. Entry and exit remains a challenge, c'est la vie!
