this site is teh official 262 reconstruction, theyve already donated one to Germany!!

awesome - you can follow the step by step construction!!

"placarded airspeed limitation"?

There's a big sign on the dash saying, "do not go over 500mph?

Yeah, that'll work.

Well you either obey placards or your wings fall off, your choice!

Placarded limits remove the responsibility for the airframe from the manufacturer when they are ignored, and are certainly cheaper than trying to fit some form of engine limiter which would be overly complex and expensive.

Most GA aircraft have placards of some sort ("no intentional spins", etc)

Ahh, a kind of really important disclaimer then?

Very much so! Aircraft operated outside the limits of the Handbook and placarded restrictions = no avenue for expensive litigation against 262 builders!

Hopefully you'd be allowed to "mock dogfight" to some degree though http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

In the case of the Me-262, the biggest risk isn't in-flight structural failure but rather loss of control due to compressibility. I would expect to see a placard at about 540 mph EAS/0.7 Mach number in order to provide a bit of safety margin.

However, the absolute limit established by Messerschmitt during the war was Mach 0.86 beyond which "There be Dragons".

Bust the limits and this sort of thing will probably happen:

The 262, like most early jet fighters, suffered from snaking at high Mach number, which made accurate tracking for a gun solution extremely difficult quite some time before the "graveyard dive" was entered. Flight in this speed range would be reasonably safe, but somewhat unpleasent.
