That "junk" has greater standoff weapons, kinetic performance, greater situational awareness with 3 radars, and more T/R modules then any aircraft but continue jumping around like the real idiot. It obvious you were a troll from your first post, trying to push your agenda.
Exposed like what? It's no different to the F-35, luckily the designers and engineers have a little more common sense and education then you, and they know you can't bend the rules of physics for the sake of internet trolling. The narcels most definitely create corner reflectors but so does every aircraft, what is important is controlling it and or ballencing all around performance with reducing radar signatures.
The SU-57 also has the ability to hit ground targets from about 300kms, much further then any F-35 or F-22 so there is no need to sacrifice kinetic performance for a flat undercarriage.

You arnt qualified to even talk about coloring books let alone about an aircraft you know nothing about.

I recommend some anger management and to finish junior high but I have a feeling you will not last long on this forum anyways.
Thank you for that amazingly insightful post but that "pathetic design" can still hit ground targets from 300km away which gives it far greater standoff range than the F-35/22, has better radar coverage and situational awareness with 3 radars, better beam tuning, supercruise, data-link that incorporates ground and air assets, has greater range, T/W ratio then any other fighter, has vector thrust, unique MIRES system and engines that put out 40,000lbs, not to mention the radar can manage and engage 80+ targets simultaneously but it's just "pathetic"
If the upgraded Flanker as you call it is pathetic then what does that make other aircraft?
