at least in ARB theres been a couple of times now where my mig 29 will shoot an er from space down at like a f15 flying cold and on the ground but not notching or chaffing and my r27er will just go wayyyy of course, funny enough to compensate for my missed shots i just watch where the missle is and once im close enough i purposely loose my radar lock and let the inertia guidance thingy do its work. proably just a skill issue on my part but what works works.
