I started working on the right wing, I build all the ribs asseblies first for both wings. Since all parts are already alodine, and primed, work goes a bit faster. Had a neighbour come in, and check my work, I am sure he knows something about wings.
First was Rib one, stiffening channes,a dn bushing guides for the flap's tube. Had to be carefu sice some rivets are pull from one side, and other from the other side,
