removed the F3 from the frame and set up F4 into the frame. Bought more Douglas fir/Birch/ �arine ply. ($67). On November 10, 2019 took both F3 and F4 to our EAA meeting in Bennington – “show and tell”. Not a tremendous start to the airplane but something to show I started. In the picture the 3/4 marine ply is in the background.
