I think all is working again now. Please leave a comment on a photo somewhere if something you need is not working still.

Next is to sand the fin/rudder to airfoil and install it.

The planned colors are similar to this model but without the garish tanks. It will have a full landing gear.

The low winter morning sun shining through the front window briefly adds a bit of light to the work area where the third filler app is on.

I finally was able to get the fairings sanded so the next area for filler is the sections made with the 1/16" stringers, top and bottom.

This one's also for him:-)

For Julnik who asked about a canopy. A lot of work will be required before it's actually glued in place!

I thinned the filler and used a palette knife to apply it to the wings. It sanded smooth fairly easily so I did the same thing on the jet intake/fairing areas. This first application is to smooth all the sections together and the top and bottom sections will get it next. When all 3 sections are done the whole thing will get an application of filler. This will dry overnight until about 11 tomorrow morning when it should be warm enough to go outside.

The fuselage is about 4" diameter and the exhaust is about 3". Notice that the bottom of the fin/rudder is curved to fit that outline. I first glued one of the stringers to C to B and then from C to A. The problem is that at Point A it's paper. Each additional stringer is glued to its neighbor so all 120+ used are all glued together. That means that the original curve established is maintained lengthwise and allows control in placement of where the stringer meets the paper. The reason you can't do all that with one piece of curved balsa is because it's a compound curve. If you covered from A to C you would lose the curve. And with all the stringers involved being glued together it's quite strong which, by the way, is why I would never use 1/32". All surfaces will get filler and that means sanding so thin wood just doesn't work. Ever.

You probably know that balsa will bend more easily from A to B than from A to C and that it will not bend in both directions at the same time.

I studied the plans quite awhile before starting and this is part of the reason why. This is one of several parts provided to cover the open areas.
