In real life, yes, the radome does have a bit of an effect, acting as an extra "wing" that provides just a bit of extra lift, from what my rw comrades told me during my rw flying days aboard the US AWACS. And it def adds some weight; it weighs 30 tons! The trainers for the US AWACS had no radome, so they had to but several 50-gal drums of water in the "aft baggage area" to simulate the weight of the rotodome.
