Just did a quickie test of roll rate, P-51B vs 190D9 (not the best roller, but both are 1.06 planes).
Took um up to 5000 feet, nose slightly up, then started five rolls, losing altitude and gaining speed as I went. Ended up at 400mph's at the end of the rolls.
Both planes did it in about 11 seconds.
