The Bf.109 K-4 with gun pods still outclimbs the F4U-4 by a significant margin. The Bf.109 K-4 with gun pods will reach 5600m in the same time that it takes the non-gun pod K-4 to reach 6000m. A minimum fuel F4U-4 reaches 5000m in the same time frame and it has to burn up around 40% of it’s ADI fluid to get that.
You are quoting stat cards. They are effectively meaningless.
Without gun pods any late Bf.109 variant can out climb and out turn the F4U-4.
With gun pods the turn rates become roughly competitive with the Bf.109s maintaining better power to weight ratios.
It does not perform better. Like most American planes the F4U-4 has a high top speed but only mediocre acceleration. It does not even begin to pull away from the Bf.109 K-4 at sea level until it reaches 570kph on the deck. And due to the fact that the Bf.109s have variable speed superchargers this difference will be even more noticeable at altitudes between 1000m - 3000m. The only place that the F4U-4 is faster than the Bf.109 K-4 is below 1000m and above 7000m; at every other altitude it is slower than the K-4.
Ground pounding is mostly irrelevant to Air EC; especially with AA being as powerful as it currently is. An F4U-4 that is loaded for ground pounding is an easy target for any Bf.109 variant.
MG.151s trade velocity for higher damage out-put. They are not less accurate than other guns but they have a lower velocity which limits their reach. At the same time .50 cals have higher velocity but they do not have the same damage output.
MG.151s work perfectly fine for deflection shots with shorter windows of opportunity that .50 cals simply do not offer.
You have never even played the F4U-4. In fact you have basically not even touched the US side of the tech tree in SB. This is why you get so much basic information wrong.
The only thing that makes the F4U-4 reasonably decent is the fact that it can sustain a reasonable turn rate for longer than previous F4U-4 variants so it can punish Bf.109 pilots when they get sloppy and decide to just pin their stick in a single direction.
It is not a 5.7 plane. It is not faster than the 5.0 Bf.109s. It is not faster than the 5.0 Ki-84 that it always faces. It does not turn better than a 109. It does not climb better either.
And before you actually complain that I am somehow biased because I play US planes…I also play German planes quite frequently and have been doing so for quite some time.
