Well, that is realy making me happy muzzleflash! Lets give some more info:
The PAK FA T-50 that you saw is the prototype for PAK FA stage I.
Stage I:
Has avionics, upgraded weapon sytems, engine's and radar from the SU-35BM.
Stage II:
Will have new avionics, new weapon systems, True 5th gen engines and a brand new AESA radar.
The T-50 has 10(!) Internal hardpoints and has 2 main weaponbays and has 2 smaller ones. It features a moveable LERX acting like a Canard but then
integrated in the acual wing. Reducing RCS. Also the fins on the back are fully movable even though they are smaller then on a SU-2*/3*, they have a
greater surface then the movable parts on the Flanker Fins.
Also the range is stated to be 5500KM!!!!!!!!!!!!!! (That is Intercontinetal!)
Hope that yields enough info to satisfy the curiosity for now
