The only way I would agree is if the radar had it`s own view,such as F6 in bomber.
This would simulate looking into the scope as the radar operator had to and would make the radar equiped plane a sitting duck much like when a bomber is in the bombsight. You wouldnt be able to look around just at the scope,IMHO it would reduce the players SA.
Now that I think about it,if it was implemented in this manner,it would be a waste of resources as very few would be willing to give up any atvantage the radar may give simply because it wouldnt be worth the risk! If we had night time,not likely then I could see a use but whether it`s on a single or twin the added weight and lack of performance just wouldnt be worth the effort!
