I dont know man, I've heard first hand that the 29A/S radars dont see jack s*** 90% of the time. Also, did you know that the frotal hemisphere of your RWR will be inhibited whenever you have a radar lock? Our SPO-15 is modelled compeltely wrong as well when it comes to displaying data and radar/emission types. So eh, it's FC3, a very dumbed down arcady simulation. I would rather have someone do a proper full fidelity Mig 29 or Su 27 model.
On the other hand the F-16 and F/A-18C radar HUGELY overperform in DCS. Almost Tomcat levels of radar.
