I will do!
However the question remains if this new image is indeed a recent one ... at first sight I seen no major differences.
But otherwise You are correct, I somewhere read it is testing the J-35's radar ... but if this is credible, I don't know.

Even though grainy, photo does make the nosecone look smaller compared to the J-20's tester. Can even make out a side window. Is there also a chin mounted EOTS? Most likely testing for J-35. What else is there really with this geometry? Certainly can't be for a flanker or JF-17.
