war thunder dose have a version of dual plane it is not exactly the same but it achieves the same result. there are values for different fin AOA limits for the R-27er and the 530D if i remember correctly. and the low smoke motor would not give a game breaking advantage it would provide more of an element of surprise for long range shots out of missile indicator range or when an opponent RWR is overwhelmed. also there should be a decent seeker upgrade from the A to B model that is not present and a small upgrade from he B to the C the r-77-1 aim-120c, AAM-4 and the mica should all have better seekers relative to the first wave of fox 3s added but only the mica does.
