Default Landing Gear Failure

According to the manual max speed with the gear extended is 350 km/h. Out of curiosity I was trying to break it today and noticed that it doesn't. Tested all the way up to a 600km/h dive then extended the gear (ie gear up, dive, then extend at 600 km/h) and had no damage.

Not a huge issue but might want to be looked at.

Edit: ok after another test at 700 km/h now the tailwheel won't raise anymore but mainwheels are still fine. 109G simulator?

sounds a little too high without having some severe effects on gear and airframe at such speeds....
iirc though, i think in previous patches a while ago,there was indeed landing gear damage and failure if you dropped it at such insane speeds.

LOL. I wonder if it affects all planes. I'll chech my P51 later.

It's an area where my good old A2A ww2 fighters do a much better modelling job...

I had tested last week with the 109, the 190, 51 and IX, and they all fail miserably to get damaged... Only thing that happens is that the undercarriage "doors" are blown away at some point...

Same limitation in IL.2 Battle of... btw....

In A2A aircraft you can get all sorts of damage from this overspeed tests, including asymmetric damage of gear and flaps and other surfaces...

In DCS and IL.2 of course control surfaces are also lost under some situations.

The limitations in the handbook may not always be due to structural strength. Sometimes the hydraulic system isn't just powerful enough to extend the gear to downlock. Or the drag produced by the gear at high speed could overwhelm the control surfaces leading to loss of control.

Yeah Retu I understand that the limit is with a hefty safety factor included but I cycled it multiple times at high speed and only the tailwheel failed. Landed afterward no problem as well. Track showed no damage in the event list.
