Trim on, trim off, and even without any flaps, a Zeke will out-turn a Hurricane. Using flaps in the Hurricane is always a mistake. To deploy flaps, you must get your speed below 160 mph. Don't use them, any pilot with even a glimmer of skill will kill the Hurri in a short second.
What I believe happened is that the guy flying the Hurricane simply managed his E better than RV6. Zekes can turn incredibly tight circles. However, if you get them too slow, you can be beaten by any fighter.
Ultra-slow, super tight turns inherently have a low rate of turn. In other words, degrees per second of turn rate. Moreover, at 500 yards the angles change little, making the Zeke extremely vulnerable to a snap-shot, at which, the Hurricane's Hispanos are extremely dangerous.
Another factor could be pulling excessive G. Nothing leads to losing the advantage faster than blacking out and not being able to track the enemy fighter, who may reverse or go vertical while you cannot see. Situational Awareness goes out the window if you can't see the enemy. Finally, Zekes are very poor rollers at speeds in excess of 300 mph. At high speed, you must maneuver in the vertical. Two reasons for this. 1) It reduces your speed rapidly, allowing you to roll faster. 2) Nothing can follow a Zero in a tight vertical loop. Nothing….
I suspect that RV6 killed his speed to the point that he became an easy snap-shot target for the faster moving Hurricane. He should also stick to a lag pursuit, rather than lead pursuit, as this only works to the Zeke's weakness in roll rate. The Hurricane can reverse much faster, or reverse into a high yo-yo, then drop in for snap-shot. And, if the Zeke pilot is pulling hard enough to blackout, he'll never see it reverse.
Zekes should fight Hurricanes using its vastly superior vertical maneuvering performance. Should the Hurricane try to do likewise, it will bleed E like a pig and become little more than a stationary target. Same tactics will work with the FM-2 and F4F-4, although both are better turners than the Hurricane IIC.
One other point. It is not unusual to encounter highly skilled pilots in the TA out to have a party at the expense of newbies. Make note of the other pilot's name and check their score before becoming too discouraged. You may have been facing an expert. In which case, consider it a valuable ACM lesson, not a beatdown.
