I was thinking about this and remembered the North American P-51 Mustang had control issues on takeoff due to insufficient rudder after the upgrade to the larger Merlin powerplant in later models. The issue concerned torque-roll during the takeoff run, which was an issue for new pilots who did not know there was a nasty roll coming during spool-up. They lost a few airframes and I do not think the problem was ever solved. This illustrates the relationship between rudder in the yaw and roll axes. It affects both.
