Do I hear some irony here?

In case I should not could you please tell me the trick how to reach 490 kph with WEP as I just get the 109 to 470 kph with Notleistung?

Wow, another mature, well thought-out reply from an Allied pilot. Grow up.

It's depressing that people get so emotionally invested in their favorite plane that they get all riled up when its weaknesses are brought into light.

that was a reply to him for being personal and trying to be a smart arse , nothing to do with the game ( looking back probably a little ott )

Really? I may be mistaken as to the speed but if I am its not off by much.
Normally Ill be in my lightly-gassed (100-200L fuel) E-4, dive for the deck from a few hundred meters, turn on the WEP and then hold it at less than 10 meters off the water.

Hmm, the original post was asking a question about the relative performance of two aircraft. The next 7 or so replies were constructive and on-topic.

Then you posted this fountain of wisdom, where you accused the original poster of whining, and then implied that the developers purposely nerfed the spitfire to stop Axis pilots from moaning:

So let me ask you this: Insuber was clearly not whining, so why did you feel it was necessary to say that he was? Do you have a personal problem with Insuber? Do you have a problem with people who fly Axis? Do you have any evidence to back up your assertions that the spitfire has been purposely made too slow?

A dive from height with less fuel will definitely see you faster than a level acceleration for a good long while. I find the 109 holds speed very well after a dive. If there were ever a "trick" I think this would be it.

That may very well be it.

I've never really done any speed tests, but Stormcrow should make sure his rads are closed and the ball is centered.

you mean like getting 490 kph for 0.5sec and then ruining one's engine?

Don't close them all the way, then.
