Did i see that correct,is the aileron still in place from the shot-off wing?

Make shure to set your fraps to more than one core and FPS to more than 30 also you can do it half size.

Yes @37 seconds,-- after the Spitfire collides with it.The aileron is flying in formation with the plane it's not attached to.

inertia?

Doubt it,there are too many variables between it and the main wing,weight,mass,centre of gravity,collision impact forces,collision impact direction of movement,etc.This follows perfectly in formation as if still joined.

2 AIs coming in collision during a coop game. Made me laugh :)

Very nice video

ps : "Ouiii fumé !" :)

It's a track, or it's recorded in real time while flying?

There's a difference between things that happen when flying vs watching the track.

In Il-2 it was worse. I had serious problems with tracks being corrupted, even offline.


As an example, I recorded this video from a track:

There were birds all around the bridge, that are not in the track as reviewed. Also vehicles behaved a little different.
