More cutting and more PSR!





Glued the two halves together and cut out the control surfaces. The joint between the surfaces and the wing looks really tight in pics I've seen. No hinges or spaces to be seen. Makes sense in a stealth aircraft. It will make my job easier cleaning it up and gluing them back on.

A little putty where I cut too far.





Exhaust is painted a metallic black for now. I'm going to try making some decals to make the surfaces look like this.....

yf-23_13_of_51

Also on the decal sheet will be different color shapes to represent different antenna etc.

A little more progress.



Planking the gap.



Back to looking like an aircraft again!

Yes,,, this is great.  Top notch concept (per my way of concepts) coming together.
Fine work.  Awaiting more progress pictures.
Black world has/had F-23 variant.  Oops - nuff said on that.

Going to work on closing up the underside today. It's mostly flat so less planking involved. I'm thinking of changing the story to it being a CIA asset. I read an article on the SR-71 that made the point that if the SR-71 was CIA funded it would have flown for a much longer time. So this will be the replacement but under CIA control. I'll have to look over my decal options again.

Not sure if the tiles are related to the ones on the shuttle but they could be.

Got the underside planked.



More putty today.





Putty palozza! I'm giving it lots of time to dry before sanding. Working on the control surfaces in the mean time.

Part 1 of putty palooza has been sanded down. Part 2 has been applied. I've been using plain old nail files/ermory boards to shape the putty and plastic. Course to cut through all the material and with a flat backing to make sure I don't cut away the putty and leave plastic high spots. I clean it up with 400 grit and will go over the whole thing with 600 before I paint. I have to watch out in areas where I applied a lot of glue as it seems to be affecting the putty. I've noticed a couple of cracks in the putty even after it was dried and sanded down. There could be traces of vapor finding its way out yet.





I had to add some plastic to build out the chines. I should have done that in the first place but oh well.



I've test fitted the stabilizers and the fit is terrible. Very little effort was made to provide a strong anchor for the pieces. I'll have to do a lot of sanding and fitting to get a tight fit as the butt joint will be the only thing holding them. I see these breaking off repeatedly in the future. Plus trying to get the angle right. Might be time to build a lego jig.

FWIW, the Italieri/Testors/Revell/Tamiya YF-23 is definitely the best 1/72 YF-23 kit out there (I have samples of all and have compared them with a Northrop 1/72 display model that was sold by their company store 'back in the day").  Still needs, as you point out, work, though.

That's some top-shelf styrene surgery there!

The rare times I get mods looking that clean it makes me almost want to dance.

Looks sharp and smooth as silk!

They're not. Both are ceramic based, but that's as far as it goes. The solid ceramic aircraft tiles are far more durable than the foamed ceramic from the Shuttle.

The small cracks are a result of the residual amounts of solvent in the putty continuing to dry even after it appears nice and solid causing the putty to shrink and then crack. For places where the spot and glaze type putty is more than a .020-.030" thick, this will continue to happen for quite a while. Weeks. Months, in some cases. The only real way to avoid it is to apply in very thin layers (like .010" per layer) and let dry for week or so between layers after sanding.

For this reason, for any areas where I am doing any real shape changes, like you are doing here, I use 2 part epoxy putty, like Miliput or Aves (prefer Aves). These do not dry, but cure. There is no releasing of solvent so no shrinking. They have their own issues, but shrinking and cracking isn't one of them.

You are quite right. I have to practice getting Aves in a thin layer. I know it involves wetting the tools with water, just have to use it a few times.

Round two of putty palooza has been sanded down. I'm waiting to apply round three to allow more solvent to escape. Plus RW stuff to attend to anyway. The chines are giving me trouble but I'll get them in shape soon.
