If I might ask? what is the cost of these units
Dave jr.
Dave, they work out about A$100 each set. Not sure if you followed any posts previous to this. I had one on SSW about 18 months back when I built my first one. With that one, I built the wing as a unit with joiner included in a one piece construction and trailing edge as we would normal and cut later to fit to fuz. It was a bit tricky when fitting to the fuz but nothing too difficult for anyone with a few full stunter models to their credit. They are quite strong being made from 6061 alloy and held together with M4 high tensile soc head screws (sorry about that but we were converted to metric back in the 70s so they are easier to get than imperial ones). The trailing edge one attaches with an M3 each side from the bottom.
I thought I'd try a different approach on the current one and jig it to the upside down fuz. I'ts all fitting ok but next time I'd leave the spar joiner a little loose in the fuz (not glued until later) as I would the trailing edge joiner. I had to crack the glue joint and move it a little for wing zero incidence. IT DOESN'T TAKE MUCH TO GET OUT OF LINE!! Z Poxy is great fo fixing the unit with bulkhead in position when wing is in right position. I also found this method better than the first attempt as a rib can be pinned to the fuz side giving the sheeting a neater fit without puting a false rib in to fill the gap (see pic).
A couple of pics showing stubs sticking out of fuz side and wing unit bound with strong thread which was stolen from wife's sewing room. The Ukranian's use kevlar thread. The other is of what shows on a wing when mounted to fuz plus a couple showing one of Derek's unit and the rest where they have hatched on my desk belong to Dave Fitz and Bill Rutherford.
Hope that explanation of my experience helps. It's the only way to travel with a model OS (totally pull-a-part that is) but also great for local transport if you have a small "riceburner" car. Thankfully I haven't been forced into one of them!!
