Taking the total kills and deaths for each unit as a crude representation of how often that particular unit is used, here are my feelings (emphasis on "feelings"):
The Panzer IV H has 17655 kills and has been killed 12907 times. Total of 30562.
I use these once in a while. This is our only tank, so its going to get a lot of use, especially in an environment that encourages the use of vehicles the way the beta terrain does. Because of these circumstances, I have no problem with the Panzer IV H.
The Ostwind has 17295 kills and has been killed 12808 times. Total of 30103.
I used these occasionally, but have not for some time. I feel that the Ostwind is modeled VERY poorly at the moment. The poor modeling coupled with the ability to spawn nearly in firing range of certain airfields has caused tremendous problems. Fortunately Pyro has stated that they are aware of the issues with the Ostwind and I hope they fix it in the next patch/version. I feel the Ostwind is broken and should be turned off until it is fixed.
The F4U-1C has 15428 kills and has been killed 10999 times. Total of 26427.
I never fly this aircraft. This aircraft bothers me a lot. Not because it is hard to kill, it isn't. Rather, because it is so bloody common. The note "F4U" over an enemy con usually signifies a lousy fight, even if they don't HO (a valid tactic IMHO) but because the skill level of most F4U-1C pilots seems quite a bit below average. There are some awesome F4U-1C pilots, but most suck. It also drives down the variety in the MA and I get tired of seeing F4U after F4U. I feel that the F4U-1C should not have been added, but it was, and we just have to deal with it. Fw190D-9, La7, Ki84b and Spitfire F.MkXIV would dent its numbers but some of those might be worse monsters, making the cure worse than the disease.
The Spitfire Mk IX has 8795 kills and has been killed 9307 times. Total of 18102.
This is my most common mount. I think it is flown too often and is hurting diversity, though not as badly as the F4U-1C. If the most popular aircraft had numbers totaling about 6000 less than the Spitfire IX, I think it make AH much more interesting, more diverse. I think I feel much like the LW fans felt in the first tour of 1.03, when the Fw190A-5 was so popular. There are players like me who like the Spitfire for itself and would fly it even if it were grossly overmatched, but many "opportunist" players fly the Spitfire, just as they drive the Ostwind and fly the F4U-1C and N1K2.
The N1K2 has 9432 kills and has been killed 8158 times. Total of 17590.
I occasionally fly this aircraft. This plane gives me headaches, I find it very hard to kill and easy to be killed by. Like the F4U-1C they are too common, but certainly on a level below. Like the Spitfire, the N1K2 is hurting diversity, but not as much as the F4U-1C. I feel that many "opportunist" players fly this aircraft because of how easy it is to be passable in it. Dedicated N1K2 flyers are a nightmare for me.
The P-51D has 6085 kills and has been killed 6399 times. Total of 12484.
I rarely fly this plane. The P-51 has a good total for a very popular and effective aircraft. I feel that the P-51 is bringing plenty to AH and does not really have a downside to it.
The Bf 109G-10 has 5189 kills and has been killed 4563 times. Total of 9752.
I occasionally fly this plane. Like the P-51, the Bf109G-10 is a good ride that has definite strengths. It increases diversity in AH. I feel that the Bf109G-10 is a good fighter if used correctly. Because it must be used correctly it does not lend itself very well to beginners.
The Typhoon IB has 5072 kills and has been killed 4326 times. Total of 9398.
I occasionally fly this aircraft. The Typhoon increases diversity, but some things seem suspect about it. I feel that the flight model on it is a bit too good. That and the fact that it has 4 Hispano cannon also cause this fighter to be used a bit by "opportunist" players.
The P-38L has 2833 kills and has been killed 4158 times. Total of 7401.
I rarely fly this aircraft. I don't think there is anything bad to be said about the inclusion of this fighter. Its kill/death ratio looks pretty bad though. That may be due to a large influx of new players this tour who grab the P-38 because of its looks, e.g. really neat looking fighter. It also might be a bit undermodeled or may have been inadequate to cope with the fighters its dealing with in AH. I feel that this fighter is a very good, all round aircraft.
The Yak-9U has 2293 kills and has been killed 2275 times. Total of 4568.
I never fly this aircraft. I think the Yak is underflown when I consider my impressions of it when flying offline. I feel that players should fly this fighter more often, but it may be suffering from a "Communist" stigma.
The Fw190A-5 has 2366 kills and has been killed 2024 times. Total of 4390.
I rarely fly this aircraft. I like the roll rate and if used properly it is VERY effective. I feel that this fighter is VERY under represented in AH. It has a good ammo load, rolls like nothing else and has guns that kill rapidly if hits are scored. The 4 cannon option is useless because of the pathetic amount of ammo the extra 2 cannon come with.
The P-47-D30 has 1722 kills and has been killed 2494 times. Total of 4216.
I rarely fly this aircraft. I'm not overly fond of the flight characteristics of the P-47 and I hate the rear view, but I love the 8 50 cals for killing AA guns. It also carries a VERY impressive amount of ordinance. I feel that, like the P-38, the P-47 may be suffering at the hands of new players and possibly a deficient flight model.
The C.205 has 1001 kills and has been killed 1328 times. Total of 2329.
I never fly this aircraft. I think that the C.205 has some very nice characteristics and would do very well in a 1942 or early '43 planeset. Unfortunately for the C.205, we have a mid 1944 planeset. I feel that the Italians could really use a better fighter, but due to their early exit from the war they may never get one. I hope there is a viable one for them though.
A couple of other things that I want to talk about here:
Many players have noted the faulty stalls. One thing to think about while talking about these (and I have noticed them as well) is that some aircraft came out of stalls very easily. I can't speak for any besides the Spitfire, but I assume it was not unique in its ease of recovery. According to the Chief Test Pilot of the Spitfire program, Jeffrey Quill, the Spitfire would bring itself out of a stall after two and a half (2 1/2) spins. He said this in regards to Spitfire up to, at least, the Spitfire MkXIV. He said that it had to be held in the spin. I would not be surprise if other aircraft, such as the A6M5b, were also easy to recover from a spin.
That said, I know some aircraft, such as the F4U, were very difficult to recover from a spin.
The other thing that I would like to comment on is the players who will ONLY fly aircraft from one nationality. I think its fine that you do this (I also think your depriving yourself some of the fun of AH, but that's your choice), but I don't think that it means HTC has to immediately give your nationality aircraft to do every job. There are some VERY significant aircraft that have not yet been modeled that may be more suitable for that job and, unfortunately, be from a nationality other than your chosen nationality. Please be gracious and allow HTC to model these other aircraft without being slammed for it.
