Russia’s big weakness is electronics. I was laughing at their latest radar that is supposed to phased-array and scary to us. Without decent signal processing, it’s about worthless. This is like the Chinese “stealth” planes that have canard winglets. Media morons don’t know that that absolutely kills your stealth.
Elevators on the nose we had a fighter in comp with them but it lost.
Canards can also be considered a kludge- a fix to an unstable design. Depends on the design, though.
