Only planes I miss from Warbirds are the warbirds P38's and the B25-H. The warbirds P38's are much more nimble and compress alot differently. Hell if I know either is right, but I did correspond with a WW2 p38/p47 vet back when on the compression issue and dive brakes/flaps. According to him compression wasn't that big an issue Iat all IRL due to the way the P38 was actually used
It does seem odd to me though that the AH verison shakes so at medium alts when the plane had a service ceiling of 40,000 feet.
