The Wing Box set is now in production and being shipped. It is available in the e-shop both on its own and in a discounted promotion combo with the Spine set (go to Now Shipping to chose which), the Combo item is KAZ007HAS). All items are currently in stock, and the web article on its assembly will be up shortly.
The Wing Box set includes both complete boxes, left and right with more than what is shown here. The instructions can be viewed from the product page in the e-shop and downloaded as a pdf.
The Wing Box set is going together very well, in this, its final testing for fit and spacial geometry verification.
Above is a shot of the process, with the spigot in place in the right box. It's made up of two parts, and the outside section is the single piece that details everything in the wing. These parts are not even glued in place, and held nicely by friction. The box floor is a single casting, and the most laboured part of the set is cutting it free from its casting block. It really isn't a big deal, but it is a relatively large part, in terms of resin components.
There are three vertical wall pieces that are added to the floor piece, as shown above. Everything comes together at 90 degree angles, and there is some grinding to do on the bottom of the floor to allow the part to clear the intake ducting of the kit. Fortunately, no modification of the intake ducts is necessary. I was originally afraid there would be, but it is simpler than I hoped. i will detail this procedure in the build article, which should be posted next week, along with a link to the instructions.
The threaded part of the spigot fits into the wing section by snapping in place. It is completely free to move.
The loose end then fits into the main spigot arm and leaves room for adjustment.
The aforementioned build article will also describe the integration of the two sets together. It's a bit of a project and there are things to consider that I will pass along to you to simplify the process.
We will begin taking orders of this set next week, and will ship a few days later in the order that they are received. Comments, questions and suggestions are welcome, as they always are.
