It seems that I am my own worst enemy lately as the aircraft I fly can't have used strong enough bobby pins to stick the wings on.

So I'm looking for some DNE speeds for all different types to keep as a reference. If anybody can help it would be greatly appreciated.

IL2 Compare has maximum dive speeds. They are not displayed on any of the charts; you have to click on the name of the plane in the menu on the left.

A LaGG-3 once fell apart on me at like 580 kmh, lol.

You might want to find the maneuver speeds (I forget the letters, V-something of course) that are the speeds where you can
safely use full deflection on ONE axis. Then if you are going faster you know to handle the plane gently to tender to
slow down first then maneuver.

Indeed Ba5tard5word, Laggs and their younger siblings Las have very low VNE. Even La-7 can only dive to about 700kph if memory serves me well. Yaks are considerably better in this regard and can follow the diving run'nineties longer. They are still inferior to German counterparts though.

Some others kites however are nearly indestructible in a dive - like a Mc200, it can dive to 1000kph, outdiving anything short of P-47 http://forums.ubi.com/images/smilies/16x16_smiley-surprised.gif:

Excellent thanks guys, it's quite a handy resource.

@max, good idea. I think it's called V(max) or maximum speed at corner. That's a pretty handy thing to know and worth looking into.

As far as I know not all the IL2 Compare max safe speeds are reliable -many are too low ...Dont get me wrong I use this software on a DAILY basis and adore it but its only a guide to V Never Exceed

WOW, i did not know that! How fast can the '47 go before it starts breaking apart? I sometimes like to just dive down from 10k and try to pull out with 1000km/h on my gauge and have the plane remain intact. It usualy takes of an aileron or the rudder, so its quite the chalange to get out intact.

I always thought the P-47 was indestructable but I managed to loose an elevator diving at 470mph. I was pulling up at the time,but not realy harshly.... :S the tempest is about the best thing I flown for diving http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

They probably apply to full one axis deflection.
