"...РЛС Су-27 (Н001) представляет собой всего лишь увеличенную версию РЛС МиГа-29 (Н019). Это хоть и вполне возможно, но все-таки спорно."
Darth, I know you speak English well, so it'll be easier for me to reply like this. Apologies. :-)
A buddy of mine, who was at the time serving in an F-15A unit, firmly held the same opinion. I know that being in the USAF (though it might've been the National Guard) doesn't qualify as an all-knowing a/c encyclopedia, but his opinion I always took into serious consideration, to put it mildly.
