Check out the Ladybug spacing - it's about the same width. The main spars are 1 3/4 X 3/4 inch thick. However the main hinge spars are a full 2X3 to prevent sagging at the hinge joint. I also added to the center spar on the front to make it a little thicker. Wslively and his WW is also a good candidate to look at for spar spacing
