Indeed. They had to do a lot of work after the T-50-1 MAKS structural mess and upgrade done on -0,-1,-2,-4,-5 frames but now they are truly getting over the hump i think and picking up the pace. Assuming T-50-7 won't give any more nasty surprises.
Mack8, in my mind, there is seems to be two "phase 2" lines. One of which are "phase 2" structural improvements and other frame modifications (like covered up nacelles, but we will know with 6-2). The "second" "phase 2" is then building upon phase 2 frame with Izd.30 engines, improved T/R's for radar and so on. That is post 2020 tho. We also know for sure about composites that has been referred to as "phase 2", i am not sure if that is longer down the road or already been fitted to -7, 6-2 and on.
To answer your question directly; 6-2 is more like phase 1.5. It won't have Izd.30 of course but it will be structurally redone. A bit back he also said that T-50-9 will be the first frame with "new engines", but i will be shocked if that means Izd.30 considering it is due to fly early next year, about same time when Izd.30 would start ground testing. Probably it is going to be fitted with whatever 710 is testing.
