No Radar is a good thing. The idea was to have a squad of KA-50s with one KA-52. The Ka-52 has the radar and uplinks to AWAC etc.It then sends target info via the datalink to the ka-50s. Having a radar turned on is like putting on a search light. It gives you away and also act as a magnet for HARM and other active radar seeking missiles.
I think many people are just too used to Hollywood's verison of warfare.
Almost all modern Airforces are starting to use a drones for the same reason. i.e. one drone out infront of the fighters/bombers etc to id targets and feed them back to the planes so they don't have to turn on their radar.
This is why computer viruses will be at the frontline from now on. The idea is to somehow insert a virus between the drones and the planes.
Yep us Nerds are the frontline in modern warfare.
