Here is a picture of just the inside rib. Note the sanded angles of the spars and the holes drilled into the end pieces.
Here is another picture of the stub wing ribs placed for trial fit. Now I have to install the WAFs again and re-set the dihedral.
View of stub wings from front. Note the piece of wood under the plane just behind the stub wings. I slide this forward until my Smart Level screams at me that I have the plane level. I use "level" as the top longeron between the spars using a four foot level.
