The bottom wings are done and are on the plane.
The frame is made per the kit. With modifications. The airfoil sections are made from cardboard with the kit graphics glued on. These airfoil sections have proven to be pretty flimsy and I add additional cardboard to the downstream location. Without the additional cardboard the airfoil sections will not stay straight and also the added wing skins will be lumpy at the airfoils. Also, my experience is that the outboard airfoil section does not work well with the wing skin at least the way that I work. So I delete it. I will write later I added wire at the outer edges that can be bent to follow the wing contours and help to create the concave airfoil section.
Note that the lower wings are rectangular and the vertical thickness decreases from inboard to outboard. And note that even though the lower wing is rectangular the airfoil sections get smaller as you go from inboard to outboard. The added downstream cardboard makes the downstream edge straight.
I built this wing structure with .032music wire to keep things straight. In the picture above is one of the wires installed. I would stack the airfoil sections and drill them together to result in the wires being in the correct position.
As mentioned above, I added another .032 music wire on the leading edge and bent it downstream at the outer edge and generally follow the contour of the wing skin. And another cardboard support is added to the outer aft edge that connects to the wire. A piece of wood is added at the location of the downstream inter wing strut. When I drill a hole for the strut there will be support inside the wing. I also add an appropriate paint color to the edges which will help later.
The lower wing skins are cut out and pre-bent. The skin edges ae also painted.
Note that the .032 wires extend inboard and will serve to attach the wings to the fuselage.
The structure is glued to the bottom and care is to correctly position it, and also to achieve the concave effect on the bottom wing surface. I also used this opportunity to re-position the side wires to move them away from the edges of the skin. In retrospect I should have moved them inward to leave two wire diameters between the wire and the skin edge. Later on I had to add MH Ready Patch to fill the gaps.
This is an end view. It is important to get the skin to follow the airfoil.
It is tricky to get the paper to follow all the way around the airfoil and reach the other side of the wing skin. But that is the goal. I found that by gluing the bottom and letting it dry and later do the top works the best.
The graphics look good.
The wings are attached by drilling holes in the fuselage side and the .032 wires ae passed through. As mentioned in an earlier post, I had placed wood supports inside the fuselage and these worked as the wings are tight and straight.
The wings are straight and the thickness gets thinner as they go outboard.
I also added the machine guns at this point.
