Well I meant maybe there's too few German aircraft to be used for racing like this? I'm not sure really, but these planes are pushing 500mph+.. I don't see too many 109's or 190's doing that without some serious modifications..
There are other classes where the planes aren't modified though, but racing is quite dangerous.. 3 people were killed last year due to crashes, so maybe people with the German planes don't want to risk it.. Who knows..
i think dago red has the record right now, with a single lap speed of 512mph, and an average qualifying speed of 507. not sure, but i think that she's the only pisotn engined unlimited racer in the 500 range right now?
as for german aircraft, there aren't any FW's flying right now, are there? and i think less than a dozen 109's?
i had read somewhere, about the modfications to the dago red. they were very very extensive, and millions of dollars.
i'm kind of doubtful that someone would take a one of a kind aircraft, and modify it like they'd need to for it to compete.
