The plans headrest is not for me.  I didn't like the triangle shape.  It reminded me of the band, "Devo", and also Saturday Night Live's "Coneheads".  Both are icons of the 80s.  I will be using a modified automotive headrest.   I will be strengthening the turtleback/canopy hoop with additional layups for safety in the event of the airplane becoming inverted while attempting a landing.   I don't have pictures of the seat brackets or the rear heat duct but they are built and  installed on the plane. I am not using the outside foot step.  I will carry a small folding step and store it inside the plane.  I like the idea of electric or mechanical slideout steps but at this point I'm happy not having the drag of the step outside the plane. What I've learned: I have learned to sand parts to make them smooth and give a more manufactured look.  None of these pictures show that but you can see it now on more recent pictures of the plane.                                                                        I have learned to take more pictures of the building process.  :)
