I had the opportunity to go 1v1 with Yeager in his hurr2 and my hurr1 last night...
Just saying "the hurr1 flies rings around the hurr2" doesn't really describe the situation. Yeager was able to HO me many many times in a row with devastating damage, when I as valiantly trying to evade the HO. All it takes is 1 ping to lose oil (and the ability to aim) pilot, or a wing, in a HO with a hurr2. Hell I tried HOing him back, but 8x 303s suck for damage. The hurr2 soaks up a LOT of damage. By the time I had got 1 kill on him (with a fresh plane) I was down to 1/2 my total ammo count. Most of my rounds HIT, as well (not so much spraying).
If (rare case) I was able to get PAST the HO, the Hurr2 flies the same as the Hurr1. In fact, it flies better because the carb doesn't cut out in nose high situations, the engine is more powerful, and it can turn just about the same, so it really does out-class the hurr1.
Versus a P40B, the hurr1 seems to easily win -- in a turn fight, anyways. Yeager got a few shots off, a few pings were received, but I usually got the better of him when he was in P40B. With the uber Hurr2c there's no reason to fly the P40B at all. Perhaps the Hurr1 should be issued to both sides? (just thinking out loud here, feel free to agree/disagree)
