Hello Gentlemen.
Flew last night in AvA.  Radar, because of base overlap, was “all seeing” above 250 feet, and there were no enemy icons.
“What a hoot!”  I lost a well-camouflaged enemy fighter three times at low level.  Additionally, I did not know what enemy aircraft I was facing until the merge.  Later the radar went down and that pretty much shut down the combat.  Big difference!
This is very close to the standard setup I flew many years ago in Fighter Ace 2.0 in the “Realistic” Arena.
I really feel, that with the numbers being what they are, that setup could be great for both Early and Mid War arenas. 
Respectfully.
