Looks like they might've painted it much similar in style to the F-22 if it's real. Going to have see a better pic.

Maybe it's not just lighter paint, but with stealth coating too. A close up of the surface would be nice.

Yes Sir! It almost looks like a break-up camo????

It's supposed to be the 2001, so the tails aren't supposed to be clipped. Now yes, it does appear that only parts of the plane is white-ish.

it does kinda look like the USAF pattern seen on F15c/d and Raptors and Lightnings but the color palette is more extreme. A very light brushed aluminum grey with rich, deep almost Royal Blue blotches.

I still can't figure out the clipped tips, maybe the, Eng or TUP have an aerodynamic theory, by the way, I'm not against it for aesthetics, but I really don't think the ventrals should go away completely, there have been way to many aircraft with not enough vertical stab.......

I guess the clipped tips might be an L/O enhancer, a little softer edges???? brat

My belief is that the change has nothing to do with aerodynamics or low observability. The original design had the edges taper in an acute angle. The material thins out as it gets close to the tip, making the structure weak near the tip. Also, stress tends to build up where there is a sharp angle. I wouldn't be surprised if the engineers had found cracks at the tip and decided to chamfer the corner for less hassle. It is a sound engineering decision.

That makes sense, thanks Eng and Merry Christmas brother, nice to have your considered opinion, as you seem to have a real grasp of this airplane. Frankly it confused me greatly at first, I appreciate your patience in explaining it to me. Since you mentioned stress, Is the wing/fuse juncture a welded tubb, seems to me that the Raptor has some welded structure??, and you seem to have a great grasp of the Raptor as well. just curious, thanks bax.
