Hmmm. The canard deltas shown up to 1:30 aren't actually Russian - maybe Chinese J-10s or something. Also, they're models and not real aircraft... The Su-35 is real enough, but the thinking has generally been that those sort of manoeuvres aren't necessarily that useful in air combat. Sure, you might be able to shake the guy off your 6, but then you're in a very low energy state and an easy target for his wingman.
Still, very spectacular and impressive flying, of both models and real ones.
