I ran some quick tests just over sea level with 50% fuel in each plane.
Comparison of some AH planes in flat rudder turn right 180dgr with full power.
190f8 50sec at 180mph
109g6 55-60sec at 200mph
La5fn 50sec at 200mph
P51d 50sec at 200mph
SpitIX 45sec 220mph
F4u1-c 45sec at 190-200mph
B17G 13-15sec at 120mph Ju88a4 60sec at 140mph
F4u looks completely normal here. I guess hazed was talking about something else.
Whats up with that b17?

Also Ju88 is bit far from 20dgr/sec that funked posted. In AH its more like 3dgr/sec.(with 180mph even less i think)
