Lets face it : P51b/D NEVER get a radiator hit
Dora/152 is so prone to radiator hits, may LW pilots in AH2 dont fly them.
OK, I support and agree with your request for a review, maybe even some revisions - but not for any of the reasons you listed.
First, it was the Luft whom first termed the Dora's "glass radiator" in the 40s, loooong before any AH2 player did. (IMHO, it's got the glass chin alright, but some days you get one every sortie, and others I've lost both cowl guns and taken a p/w as some of the least of my damage issues but still had a perfectly instact radiator and oil system.)
Second, not many people get radiator strikes against a mustang because the way its modeled and flown, you need a near clean open shot of their belly to ping the coolant system. Most shots, most angles, you'd need to shoot through two other major components to reach the radiator system - included amongst that list is the pilot, fueselage, and aux fuel tank (most being much nicer "sweet spots" to land a good bead on for a kill).
Since we're just griping here, how about a look into that Dora's "fabric and foil" tail.

Last time I took off a dora, I did 2 flights. 15 minutes getting to alt and into the area, 1 ping radiator hits on both flights, and this was taking hits from behind, not leading with my nose.
Plane went into the hangar and has stayed.
That has been curious to me many times, and likely a legitimate claim - with such a forward-placed system, it sure does often take punishment from behind and through the rest of the aircraft.
