Nashwan,
Tempest will easily out run and out climb an F4U-1C at the altitudes where most fighting occurs. The fastest "down low" aircraft we have is the Typhoon at about 375 on the deck. The much requested Fw190D-9 with MW50 will do 380 on the deck. The Tempest will do 400 on the deck.
It has 4 Hispano MkV cannon as opposed to 4 Hispano MkII cannon, admittedly with less ammo.
At worst, its manueverability would be about the same, except it would accelerate much better.
Those are the reasons why the Tempest would be too powerful.
In my opinion the Tempest would be more imbalancing than the Spitfire MkXIV and I continue to think it silly that the LW fans are suggesting that the RAF receive Tempests as our late war fighter. The whinning about Tempest dweebs that would follow the introduction of the Tempest into AH would be deafening.
As I stated in my first post, I do not believe that there is a true (not a slight refinement of a 1942 aircraft) late war (1944) RAF aircraft that should be added to AH. Thay are all too good for the current planeset and to bring the rest of the planeset up to their level would mean the absolute obsoletence of the Bf109F-4, Spitfire MkVb, C.202 and A6M5b as well as any similar aircraft.
So bring on the Spitfire MkXVI, Mosquito B.MkIX, Mosquito FB.MkVI and Hurricane MkIIa and IIc.
