Back on topic:
I did a quick test with both 110 and hurricane at bouncy landings, they seem to break at the same kind of punishment as the P-51 in the video. I've destroyed these components:
-Landing gear kinematic failure
-Landing gear shock failure
-Landing gear downlock destroyed
And blown the tires.
Normally the tires blow causing a nose-over. Actually 99% of the time they blow, then the other failures seem a little random, which is OK.
I don't think the impact force is too wrong, It also seems that fuel and payload plays a role here and that's good to see!
As for landing, having landed a real plane a few times, I was shocked how easy it actually is. The secret of being idolized as a pilot is much the same as a magician. Don't reveal your tricks/how it's done, it's so much easier than most people imagine.
