Agreed, which is exactly the types of things I was pointing out in my post #34 on this thread.Anyone who doesn't sleep during math and science classes can tell that thing is too small to carry any practical payload, and the cockpit is too crude for anything more than flight control; sure that'd be enough for a concept-proving airframe or even showcasing FBW technology if they go that far, but if they ain't planning to churn out kamikaze planes, then the practical model have to be bigger for:
1. a sizable weapon bay for a practical payload;
2. twin engine plus practical internal fuel storage (unless you got something as badass as P&W F135 series); and
3. room for radar and avionics that's required for combat missions.
Other than that, it's just not practical and not even worth the 15-minutes-of-fame to flaunt...despite all the shortcomings, Project 718 or J-31 as least have a sizable airframe for such practical potentials...and most importantly, they did flew the real deal, not a scaled RC model.
Showcasing a study model isn't good propaganda, unless your goal is to get "nice sci-fi model you got there" kind of comment from the outside world.
But the one group they will probably be able to fool...because they have pretty much complete control of the media...are many of their own citizens.
